+# Action Cable – Integrated WebSockets for Rails
+
+Action Cable seamlessly integrates WebSockets with the rest of your Rails application.
+It allows for real-time features to be written in Ruby in the same style
+and form as the rest of your Rails application, while still being performant
+and scalable. It's a full-stack offering that provides both a client-side
+JavaScript framework and a server-side Ruby framework. You have access to your full
+domain model written with Active Record or your ORM of choice.
+
+## Terminology
+
+A single Action Cable server can handle multiple connection instances. It has one
+connection instance per WebSocket connection. A single user may have multiple
+WebSockets open to your application if they use multiple browser tabs or devices.
+The client of a WebSocket connection is called the consumer.
+
+Each consumer can in turn subscribe to multiple cable channels. Each channel encapsulates
+a logical unit of work, similar to what a controller does in a regular MVC setup. For example,
+you could have a `ChatChannel` and an `AppearancesChannel`, and a consumer could be subscribed to either
+or to both of these channels. At the very least, a consumer should be subscribed to one channel.
+
+When the consumer is subscribed to a channel, they act as a subscriber. The connection between
+the subscriber and the channel is, surprise-surprise, called a subscription. A consumer
+can act as a subscriber to a given channel any number of times. For example, a consumer
+could subscribe to multiple chat rooms at the same time. (And remember that a physical user may
+have multiple consumers, one per tab/device open to your connection).
+
+Each channel can then again be streaming zero or more broadcastings. A broadcasting is a
+pubsub link where anything transmitted by the broadcaster is sent directly to the channel
+subscribers who are streaming that named broadcasting.
+
+As you can see, this is a fairly deep architectural stack. There's a lot of new terminology
+to identify the new pieces, and on top of that, you're dealing with both client and server side
+reflections of each unit.
+
+## Examples
+
+### A full-stack example
+
+The first thing you must do is define your `ApplicationCable::Connection` class in Ruby. This
+is the place where you authorize the incoming connection, and proceed to establish it,
+if all is well. Here's the simplest example starting with the server-side connection class:
+
+```ruby
+# app/channels/application_cable/connection.rb
+module ApplicationCable
+  class Connection < ActionCable::Connection::Base
+    identified_by :current_user
+
+    def connect
+      self.current_user = find_verified_user
+    end
+
+    private
+      def find_verified_user
+        if verified_user = User.find_by(id: cookies.signed[:user_id])
+          verified_user
+        else
+          reject_unauthorized_connection
+        end
+      end
+  end
+end
+```
+Here `identified_by` is a connection identifier that can be used to find the specific connection again or later.
+Note that anything marked as an identifier will automatically create a delegate by the same name on any channel instances created off the connection.
+
+This relies on the fact that you will already have handled authentication of the user, and
+that a successful authentication sets a signed cookie with the `user_id`. This cookie is then
+automatically sent to the connection instance when a new connection is attempted, and you
+use that to set the `current_user`. By identifying the connection by this same current_user,
+you're also ensuring that you can later retrieve all open connections by a given user (and
+potentially disconnect them all if the user is deleted or deauthorized).
+
+Next, you should define your `ApplicationCable::Channel` class in Ruby. This is the place where you put
+shared logic between your channels.
+
+```ruby
+# app/channels/application_cable/channel.rb
+module ApplicationCable
+  class Channel < ActionCable::Channel::Base
+  end
+end
+```
+
+The client-side needs to setup a consumer instance of this connection. That's done like so:
+
+```js
+// app/assets/javascripts/cable.js
+//= require action_cable
+//= require_self
+//= require_tree ./channels
+
+(function() {
+  this.App || (this.App = {});
+
+  App.cable = ActionCable.createConsumer("ws://cable.example.com");
+}).call(this);
+```
+
+The `ws://cable.example.com` address must point to your Action Cable server(s), and it
+must share a cookie namespace with the rest of the application (which may live under http://example.com).
+This ensures that the signed cookie will be correctly sent.
+
+That's all you need to establish the connection! But of course, this isn't very useful in
+itself. This just gives you the plumbing. To make stuff happen, you need content. That content
+is defined by declaring channels on the server and allowing the consumer to subscribe to them.
+
+
+### Channel example 1: User appearances
+
+Here's a simple example of a channel that tracks whether a user is online or not, and also what page they are currently on.
+(This is useful for creating presence features like showing a green dot next to a user's name if they're online).
+
+First you declare the server-side channel:
+
+```ruby
+# app/channels/appearance_channel.rb
+class AppearanceChannel < ApplicationCable::Channel
+  def subscribed
+    current_user.appear
+  end
+
+  def unsubscribed
+    current_user.disappear
+  end
+
+  def appear(data)
+    current_user.appear on: data['appearing_on']
+  end
+
+  def away
+    current_user.away
+  end
+end
+```
+
+The `#subscribed` callback is invoked when, as we'll show below, a client-side subscription is initiated. In this case,
+we take that opportunity to say "the current user has indeed appeared". That appear/disappear API could be backed by
+Redis or a database or whatever else. Here's what the client-side of that looks like:
+
+```coffeescript
+# app/assets/javascripts/cable/subscriptions/appearance.coffee
+App.cable.subscriptions.create "AppearanceChannel",
+  # Called when the subscription is ready for use on the server
+  connected: ->
+    @install()
+    @appear()
+
+  # Called when the WebSocket connection is closed
+  disconnected: ->
+    @uninstall()
+
+  # Called when the subscription is rejected by the server
+  rejected: ->
+    @uninstall()
+
+  appear: ->
+    # Calls `AppearanceChannel#appear(data)` on the server
+    @perform("appear", appearing_on: $("main").data("appearing-on"))
+
+  away: ->
+    # Calls `AppearanceChannel#away` on the server
+    @perform("away")
+
+
+  buttonSelector = "[data-behavior~=appear_away]"
+
+  install: ->
+    $(document).on "turbolinks:load.appearance", =>
+      @appear()
+
+    $(document).on "click.appearance", buttonSelector, =>
+      @away()
+      false
+
+    $(buttonSelector).show()
+
+  uninstall: ->
+    $(document).off(".appearance")
+    $(buttonSelector).hide()
+```
+
+Simply calling `App.cable.subscriptions.create` will setup the subscription, which will call `AppearanceChannel#subscribed`,
+which in turn is linked to the original `App.cable` -> `ApplicationCable::Connection` instances.
+
+Next, we link the client-side `appear` method to `AppearanceChannel#appear(data)`. This is possible because the server-side
+channel instance will automatically expose the public methods declared on the class (minus the callbacks), so that these
+can be reached as remote procedure calls via a subscription's `perform` method.
+
+### Channel example 2: Receiving new web notifications
+
+The appearance example was all about exposing server functionality to client-side invocation over the WebSocket connection.
+But the great thing about WebSockets is that it's a two-way street. So now let's show an example where the server invokes
+an action on the client.
+
+This is a web notification channel that allows you to trigger client-side web notifications when you broadcast to the right
+streams:
+
+```ruby
+# app/channels/web_notifications_channel.rb
+class WebNotificationsChannel < ApplicationCable::Channel
+  def subscribed
+    stream_from "web_notifications_#{current_user.id}"
+  end
+end
+```
+
+```coffeescript
+# Client-side, which assumes you've already requested the right to send web notifications
+App.cable.subscriptions.create "WebNotificationsChannel",
+  received: (data) ->
+    new Notification data["title"], body: data["body"]
+```
+
+```ruby
+# Somewhere in your app this is called, perhaps from a NewCommentJob
+ActionCable.server.broadcast \
+  "web_notifications_#{current_user.id}", { title: 'New things!', body: 'All the news that is fit to print' }
+```
+
+The `ActionCable.server.broadcast` call places a message in the Action Cable pubsub queue under a separate broadcasting name for each user. For a user with an ID of 1, the broadcasting name would be `web_notifications_1`.
+The channel has been instructed to stream everything that arrives at `web_notifications_1` directly to the client by invoking the
+`#received(data)` callback. The data is the hash sent as the second parameter to the server-side broadcast call, JSON encoded for the trip
+across the wire, and unpacked for the data argument arriving to `#received`.
+
+
+### Passing Parameters to Channel
+
+You can pass parameters from the client side to the server side when creating a subscription. For example:
+
+```ruby
+# app/channels/chat_channel.rb
+class ChatChannel < ApplicationCable::Channel
+  def subscribed
+    stream_from "chat_#{params[:room]}"
+  end
+end
+```
+
+If you pass an object as the first argument to `subscriptions.create`, that object will become the params hash in your cable channel. The keyword `channel` is required.
+
+```coffeescript
+# Client-side, which assumes you've already requested the right to send web notifications
+App.cable.subscriptions.create { channel: "ChatChannel", room: "Best Room" },
+  received: (data) ->
+    @appendLine(data)
+
+  appendLine: (data) ->
+    html = @createLine(data)
+    $("[data-chat-room='Best Room']").append(html)
+
+  createLine: (data) ->
+    """
+    <article class="chat-line">
+      <span class="speaker">#{data["sent_by"]}</span>
+      <span class="body">#{data["body"]}</span>
+    </article>
+    """
+```
+
+```ruby
+# Somewhere in your app this is called, perhaps from a NewCommentJob
+ActionCable.server.broadcast \
+  "chat_#{room}", { sent_by: 'Paul', body: 'This is a cool chat app.' }
+```
+
+
+### Rebroadcasting message
+
+A common use case is to rebroadcast a message sent by one client to any other connected clients.
+
+```ruby
+# app/channels/chat_channel.rb
+class ChatChannel < ApplicationCable::Channel
+  def subscribed
+    stream_from "chat_#{params[:room]}"
+  end
+
+  def receive(data)
+    ActionCable.server.broadcast "chat_#{params[:room]}", data
+  end
+end
+```
+
+```coffeescript
+# Client-side, which assumes you've already requested the right to send web notifications
+App.chatChannel = App.cable.subscriptions.create { channel: "ChatChannel", room: "Best Room" },
+  received: (data) ->
+    # data => { sent_by: "Paul", body: "This is a cool chat app." }
+
+App.chatChannel.send({ sent_by: "Paul", body: "This is a cool chat app." })
+```
+
+The rebroadcast will be received by all connected clients, _including_ the client that sent the message. Note that params are the same as they were when you subscribed to the channel.
+
+
+### More complete examples
+
+See the [rails/actioncable-examples](https://github.com/rails/actioncable-examples) repository for a full example of how to setup Action Cable in a Rails app, and how to add channels.
+
+## Configuration
+
+Action Cable has three required configurations: a subscription adapter, allowed request origins, and the cable server URL (which can optionally be set on the client side).
+
+### Redis
+
+By default, `ActionCable::Server::Base` will look for a configuration file in `Rails.root.join('config/cable.yml')`.
+This file must specify an adapter and a URL for each Rails environment. It may use the following format:
+
+```yaml
+production: &production
+  adapter: redis
+  url: redis://10.10.3.153:6381
+development: &development
+  adapter: redis
+  url: redis://localhost:6379
+test: *development
+```
+
+You can also change the location of the Action Cable config file in a Rails initializer with something like:
+
+```ruby
+Rails.application.paths.add "config/cable", with: "somewhere/else/cable.yml"
+```
+
+### Allowed Request Origins
+
+Action Cable will only accept requests from specific origins.
+
+By default, only an origin matching the cable server itself will be permitted.
+Additional origins can be specified using strings or regular expressions, provided in an array.
+
+```ruby
+Rails.application.config.action_cable.allowed_request_origins = ['http://rubyonrails.com', /http:\/\/ruby.*/]
+```
+
+When running in the development environment, this defaults to "http://localhost:3000".
+
+To disable protection and allow requests from any origin:
+
+```ruby
+Rails.application.config.action_cable.disable_request_forgery_protection = true
+```
+
+To disable automatic access for same-origin requests, and strictly allow
+only the configured origins:
+
+```ruby
+Rails.application.config.action_cable.allow_same_origin_as_host = false
+```
+
+### Consumer Configuration
+
+Once you have decided how to run your cable server (see below), you must provide the server URL (or path) to your client-side setup.
+There are two ways you can do this.
+
+The first is to simply pass it in when creating your consumer. For a standalone server,
+this would be something like: `App.cable = ActionCable.createConsumer("ws://example.com:28080")`, and for an in-app server,
+something like: `App.cable = ActionCable.createConsumer("/cable")`.
+
+The second option is to pass the server URL through the `action_cable_meta_tag` in your layout.
+This uses a URL or path typically set via `config.action_cable.url` in the environment configuration files, or defaults to "/cable".
+
+This method is especially useful if your WebSocket URL might change between environments. If you host your production server via https, you will need to use the wss scheme
+for your Action Cable server, but development might remain http and use the ws scheme. You might use localhost in development and your
+domain in production.
+
+In any case, to vary the WebSocket URL between environments, add the following configuration to each environment:
+
+```ruby
+config.action_cable.url = "ws://example.com:28080"
+```
+
+Then add the following line to your layout before your JavaScript tag:
+
+```erb
+<%= action_cable_meta_tag %>
+```
+
+And finally, create your consumer like so:
+
+```coffeescript
+App.cable = ActionCable.createConsumer()
+```
+
+### Other Configurations
+
+The other common option to configure is the log tags applied to the per-connection logger. Here's an example that uses the user account id if available, else "no-account" while tagging:
+
+```ruby
+config.action_cable.log_tags = [
+  -> request { request.env['user_account_id'] || "no-account" },
+  :action_cable,
+  -> request { request.uuid }
+]
+```
+
+For a full list of all configuration options, see the `ActionCable::Server::Configuration` class.
+
+Also note that your server must provide at least the same number of database connections as you have workers. The default worker pool is set to 4, so that means you have to make at least that available. You can change that in `config/database.yml` through the `pool` attribute.
+
+
+## Running the cable server
+
+### Standalone
+The cable server(s) is separated from your normal application server. It's still a Rack application, but it is its own Rack
+application. The recommended basic setup is as follows:
+
+```ruby
+# cable/config.ru
+require ::File.expand_path('../../config/environment', __FILE__)
+Rails.application.eager_load!
+
+run ActionCable.server
+```
+
+Then you start the server using a binstub in bin/cable ala:
+```sh
+#!/bin/bash
+bundle exec puma -p 28080 cable/config.ru
+```
+
+The above will start a cable server on port 28080.
+
+### In app
+
+If you are using a server that supports the [Rack socket hijacking API](http://www.rubydoc.info/github/rack/rack/file/SPEC#Hijacking), Action Cable can run alongside your Rails application. For example, to listen for WebSocket requests on `/websocket`, specify that path to `config.action_cable.mount_path`:
+
+```ruby
+# config/application.rb
+class Application < Rails::Application
+  config.action_cable.mount_path = '/websocket'
+end
+```
+
+For every instance of your server you create and for every worker your server spawns, you will also have a new instance of Action Cable, but the use of Redis keeps messages synced across connections.
+
+### Notes
+
+Beware that currently, the cable server will _not_ auto-reload any changes in the framework. As we've discussed, long-running cable connections mean long-running objects. We don't yet have a way of reloading the classes of those objects in a safe manner. So when you change your channels, or the model your channels use, you must restart the cable server.
+
+We'll get all this abstracted properly when the framework is integrated into Rails.
+
+The WebSocket server doesn't have access to the session, but it has access to the cookies. This can be used when you need to handle authentication. You can see one way of doing that with Devise in this [article](http://www.rubytutorial.io/actioncable-devise-authentication).
+
+## Dependencies
+
+Action Cable provides a subscription adapter interface to process its pubsub internals. By default, asynchronous, inline, PostgreSQL, evented Redis, and non-evented Redis adapters are included. The default adapter in new Rails applications is the asynchronous (`async`) adapter. To create your own adapter, you can look at `ActionCable::SubscriptionAdapter::Base` for all methods that must be implemented, and any of the adapters included within Action Cable as example implementations.
+
+The Ruby side of things is built on top of [websocket-driver](https://github.com/faye/websocket-driver-ruby), [nio4r](https://github.com/celluloid/nio4r), and [concurrent-ruby](https://github.com/ruby-concurrency/concurrent-ruby).
+
+
+## Deployment
+
+Action Cable is powered by a combination of WebSockets and threads. All of the
+connection management is handled internally by utilizing Ruby’s native thread
+support, which means you can use all your regular Rails models with no problems
+as long as you haven’t committed any thread-safety sins.
+
+The Action Cable server does _not_ need to be a multi-threaded application server.
+This is because Action Cable uses the [Rack socket hijacking API](http://www.rubydoc.info/github/rack/rack/file/SPEC#Hijacking)
+to take over control of connections from the application server. Action Cable
+then manages connections internally, in a multithreaded manner, regardless of
+whether the application server is multi-threaded or not. So Action Cable works
+with all the popular application servers -- Unicorn, Puma and Passenger.
+
+Action Cable does not work with WEBrick, because WEBrick does not support the
+Rack socket hijacking API.
+
+## Frontend assets
+
+Action Cable's frontend assets are distributed through two channels: the
+official gem and npm package, both titled `actioncable`.
+
+### Gem usage
+
+Through the `actioncable` gem, Action Cable's frontend assets are
+available through the Rails Asset Pipeline. Create a `cable.js` or
+`cable.coffee` file (this is automatically done for you with Rails
+generators), and then simply require the assets:
+
+In JavaScript...
+
+```javascript
+//= require action_cable
+```
+
+... and in CoffeeScript:
+
+```coffeescript
+#= require action_cable
+```
+
+### npm usage
+
+In addition to being available through the `actioncable` gem, Action Cable's
+frontend JS assets are also bundled in an officially supported npm module,
+intended for usage in standalone frontend applications that communicate with a
+Rails application. A common use case for this could be if you have a decoupled
+frontend application written in React, Ember.js, etc. and want to add real-time
+WebSocket functionality.
+
+### Installation
+
+```
+npm install actioncable --save
+```
+
+### Usage
+
+The `ActionCable` constant is available as a `require`-able module, so
+you only have to require the package to gain access to the API that is
+provided.
+
+In JavaScript...
+
+```javascript
+ActionCable = require('actioncable')
+
+var cable = ActionCable.createConsumer('wss://RAILS-API-PATH.com/cable')
+
+cable.subscriptions.create('AppearanceChannel', {
+  // normal channel code goes here...
+});
+```
+
+and in CoffeeScript...
+
+```coffeescript
+ActionCable = require('actioncable')
+
+cable = ActionCable.createConsumer('wss://RAILS-API-PATH.com/cable')
+
+cable.subscriptions.create 'AppearanceChannel',
+    # normal channel code goes here...
+```

+module ActionCable
+  module Channel
+    # The channel provides the basic structure of grouping behavior into logical units when communicating over the WebSocket connection.
+    # You can think of a channel like a form of controller, but one that's capable of pushing content to the subscriber in addition to simply
+    # responding to the subscriber's direct requests.
+    #
+    # Channel instances are long-lived. A channel object will be instantiated when the cable consumer becomes a subscriber, and then
+    # lives until the consumer disconnects. This may be seconds, minutes, hours, or even days. That means you have to take special care
+    # not to do anything silly in a channel that would balloon its memory footprint or whatever. The references are forever, so they won't be released
+    # as is normally the case with a controller instance that gets thrown away after every request.
+    #
+    # Long-lived channels (and connections) also mean you're responsible for ensuring that the data is fresh. If you hold a reference to a user
+    # record, but the name is changed while that reference is held, you may be sending stale data if you don't take precautions to avoid it.
+    #
+    # The upside of long-lived channel instances is that you can use instance variables to keep reference to objects that future subscriber requests
+    # can interact with. Here's a quick example:
+    #
+    #   class ChatChannel < ApplicationCable::Channel
+    #     def subscribed
+    #       @room = Chat::Room[params[:room_number]]
+    #     end
+    #
+    #     def speak(data)
+    #       @room.speak data, user: current_user
+    #     end
+    #   end
+    #
+    # The #speak action simply uses the Chat::Room object that was created when the channel was first subscribed to by the consumer when that
+    # subscriber wants to say something in the room.
+    #
+    # == Action processing
+    #
+    # Unlike subclasses of ActionController::Base, channels do not follow a RESTful
+    # constraint form for their actions. Instead, Action Cable operates through a
+    # remote-procedure call model. You can declare any public method on the
+    # channel (optionally taking a <tt>data</tt> argument), and this method is
+    # automatically exposed as callable to the client.
+    #
+    # Example:
+    #
+    #   class AppearanceChannel < ApplicationCable::Channel
+    #     def subscribed
+    #       @connection_token = generate_connection_token
+    #     end
+    #
+    #     def unsubscribed
+    #       current_user.disappear @connection_token
+    #     end
+    #
+    #     def appear(data)
+    #       current_user.appear @connection_token, on: data['appearing_on']
+    #     end
+    #
+    #     def away
+    #       current_user.away @connection_token
+    #     end
+    #
+    #     private
+    #       def generate_connection_token
+    #         SecureRandom.hex(36)
+    #       end
+    #   end
+    #
+    # In this example, the subscribed and unsubscribed methods are not callable methods, as they
+    # were already declared in ActionCable::Channel::Base, but <tt>#appear</tt>
+    # and <tt>#away</tt> are. <tt>#generate_connection_token</tt> is also not
+    # callable, since it's a private method. You'll see that appear accepts a data
+    # parameter, which it then uses as part of its model call. <tt>#away</tt>
+    # does not, since it's simply a trigger action.
+    #
+    # Also note that in this example, <tt>current_user</tt> is available because
+    # it was marked as an identifying attribute on the connection. All such
+    # identifiers will automatically create a delegation method of the same name
+    # on the channel instance.
+    #
+    # == Rejecting subscription requests
+    #
+    # A channel can reject a subscription request in the #subscribed callback by
+    # invoking the #reject method:
+    #
+    #   class ChatChannel < ApplicationCable::Channel
+    #     def subscribed
+    #       @room = Chat::Room[params[:room_number]]
+    #       reject unless current_user.can_access?(@room)
+    #     end
+    #   end
+    #
+    # In this example, the subscription will be rejected if the
+    # <tt>current_user</tt> does not have access to the chat room. On the
+    # client-side, the <tt>Channel#rejected</tt> callback will get invoked when
+    # the server rejects the subscription request.

+module ActionCable

+    # Streams allow channels to route broadcastings to the subscriber. A broadcasting is, as discussed elsewhere, a pubsub queue where any data
+    # placed into it is automatically sent to the clients that are connected at that time. It's purely an online queue, though. If you're not
+    # streaming a broadcasting at the very moment it sends out an update, you will not get that update, even if you connect after it has been sent.
+    #
+    # Most commonly, the streamed broadcast is sent straight to the subscriber on the client-side. The channel just acts as a connector between
+    # the two parties (the broadcaster and the channel subscriber). Here's an example of a channel that allows subscribers to get all new
+    # comments on a given page:
+    #
+    #   class CommentsChannel < ApplicationCable::Channel
+    #     def follow(data)
+    #       stream_from "comments_for_#{data['recording_id']}"
+    #     end
+    #
+    #     def unfollow
+    #       stop_all_streams
+    #     end
+    #   end
+    #
+    # Based on the above example, the subscribers of this channel will get whatever data is put into the,
+    # let's say, <tt>comments_for_45</tt> broadcasting as soon as it's put there.
+    #
+    # An example broadcasting for this channel looks like so:
+    #
+    #   ActionCable.server.broadcast "comments_for_45", author: 'DHH', content: 'Rails is just swell'
+    #
+    # If you have a stream that is related to a model, then the broadcasting used can be generated from the model and channel.
+    # The following example would subscribe to a broadcasting like <tt>comments:Z2lkOi8vVGVzdEFwcC9Qb3N0LzE</tt>.
+    #
+    #   class CommentsChannel < ApplicationCable::Channel
+    #     def subscribed
+    #       post = Post.find(params[:id])
+    #       stream_for post
+    #     end
+    #   end
+    #
+    # You can then broadcast to this channel using:
+    #
+    #   CommentsChannel.broadcast_to(@post, @comment)
+    #
+    # If you don't just want to parlay the broadcast unfiltered to the subscriber, you can also supply a callback that lets you alter what is sent out.
+    # The below example shows how you can use this to provide performance introspection in the process:
+    #
+    #   class ChatChannel < ApplicationCable::Channel
+    #     def subscribed
+    #       @room = Chat::Room[params[:room_number]]

+Description:
+============
+    Stubs out a new cable channel for the server (in Ruby) and client (in CoffeeScript).
+    Pass the channel name, either CamelCased or under_scored, and an optional list of channel actions as arguments.
+
+    Note: Turn on the cable connection in app/assets/javascripts/cable.js after generating any channels.
+
+Example:
+========
+    rails generate channel Chat speak
+
+    creates a Chat channel class and CoffeeScript asset:
+        Channel:    app/channels/chat_channel.rb
+        Assets:     app/assets/javascripts/channels/chat.coffee

+= Action Mailer -- Easy email delivery and testing
+
+Action Mailer is a framework for designing email service layers. These layers
+are used to consolidate code for sending out forgotten passwords, welcome
+wishes on signup, invoices for billing, and any other use case that requires
+a written notification to either a person or another system.
+
+Action Mailer is in essence a wrapper around Action Controller and the
+Mail gem.  It provides a way to make emails using templates in the same
+way that Action Controller renders views using templates.
+
+Additionally, an Action Mailer class can be used to process incoming email,
+such as allowing a blog to accept new posts from an email (which could even
+have been sent from a phone).
+
+== Sending emails
+
+The framework works by initializing any instance variables you want to be
+available in the email template, followed by a call to +mail+ to deliver
+the email.
+
+This can be as simple as:
+
+  class Notifier < ActionMailer::Base
+    default from: 'system@loudthinking.com'
+
+    def welcome(recipient)
+      @recipient = recipient
+      mail(to: recipient,
+           subject: "[Signed up] Welcome #{recipient}")
+    end
+  end
+
+The body of the email is created by using an Action View template (regular
+ERB) that has the instance variables that are declared in the mailer action.
+
+So the corresponding body template for the method above could look like this:
+
+  Hello there,
+
+  Mr. <%= @recipient %>
+
+  Thank you for signing up!
+
+If the recipient was given as "david@loudthinking.com", the email
+generated would look like this:
+
+  Date: Mon, 25 Jan 2010 22:48:09 +1100
+  From: system@loudthinking.com
+  To: david@loudthinking.com
+  Message-ID: <4b5d84f9dd6a5_7380800b81ac29578@void.loudthinking.com.mail>
+  Subject: [Signed up] Welcome david@loudthinking.com
+  Mime-Version: 1.0
+  Content-Type: text/plain;
+  	charset="US-ASCII";
+  Content-Transfer-Encoding: 7bit
+
+  Hello there,
+
+  Mr. david@loudthinking.com
+
+  Thank you for signing up!
+
+In order to send mails, you simply call the method and then call +deliver_now+ on the return value.
+
+Calling the method returns a Mail Message object:
+
+  message = Notifier.welcome("david@loudthinking.com")   # => Returns a Mail::Message object
+  message.deliver_now                                    # => delivers the email
+
+Or you can just chain the methods together like:
+
+  Notifier.welcome("david@loudthinking.com").deliver_now # Creates the email and sends it immediately
+
+== Setting defaults
+
+It is possible to set default values that will be used in every method in your
+Action Mailer class. To implement this functionality, you just call the public
+class method +default+ which you get for free from <tt>ActionMailer::Base</tt>.
+This method accepts a Hash as the parameter. You can use any of the headers,
+email messages have, like +:from+ as the key. You can also pass in a string as
+the key, like "Content-Type", but Action Mailer does this out of the box for you,
+so you won't need to worry about that. Finally, it is also possible to pass in a
+Proc that will get evaluated when it is needed.
+
+Note that every value you set with this method will get overwritten if you use the
+same key in your mailer method.
+
+Example:
+
+  class AuthenticationMailer < ActionMailer::Base
+    default from: "awesome@application.com", subject: Proc.new { "E-mail was generated at #{Time.now}" }
+    .....
+  end
+
+== Receiving emails
+
+To receive emails, you need to implement a public instance method called
++receive+ that takes an email object as its single parameter. The Action Mailer
+framework has a corresponding class method, which is also called +receive+, that
+accepts a raw, unprocessed email as a string, which it then turns into the email
+object and calls the receive instance method.
+
+Example:
+
+  class Mailman < ActionMailer::Base
+    def receive(email)
+      page = Page.find_by(address: email.to.first)
+      page.emails.create(
+        subject: email.subject, body: email.body
+      )
+
+      if email.has_attachments?
+        email.attachments.each do |attachment|
+          page.attachments.create({
+            file: attachment, description: email.subject
+          })
+        end
+      end
+    end
+  end
+
+This Mailman can be the target for Postfix or other MTAs. In Rails, you would use
+the runner in the trivial case like this:
+
+  rails runner 'Mailman.receive(STDIN.read)'
+
+However, invoking Rails in the runner for each mail to be received is very
+resource intensive. A single instance of Rails should be run within a daemon, if
+it is going to process more than just a limited amount of email.
+
+== Configuration
+
+The Base class has the full list of configuration options. Here's an example:
+
+  ActionMailer::Base.smtp_settings = {
+    address:        'smtp.yourserver.com', # default: localhost
+    port:           '25',                  # default: 25
+    user_name:      'user',
+    password:       'pass',
+    authentication: :plain                 # :plain, :login or :cram_md5
+  }
+
+

+
+  $ gem install actionmailer

+  # Action Mailer allows you to send email from your application using a mailer model and views.
+  #
+  # = Mailer Models
+  #
+  # To use Action Mailer, you need to create a mailer model.
+  #
+  #   $ rails generate mailer Notifier
+  #
+  # The generated model inherits from <tt>ApplicationMailer</tt> which in turn
+  # inherits from <tt>ActionMailer::Base</tt>. A mailer model defines methods
+  # used to generate an email message. In these methods, you can setup variables to be used in
+  # the mailer views, options on the mail itself such as the <tt>:from</tt> address, and attachments.
+  #
+  #   class ApplicationMailer < ActionMailer::Base
+  #     default from: 'from@example.com'
+  #     layout 'mailer'
+  #   end
+  #
+  #   class NotifierMailer < ApplicationMailer
+  #     default from: 'no-reply@example.com',
+  #             return_path: 'system@example.com'
+  #
+  #     def welcome(recipient)
+  #       @account = recipient
+  #       mail(to: recipient.email_address_with_name,
+  #            bcc: ["bcc@example.com", "Order Watcher <watcher@example.com>"])
+  #     end
+  #   end
+  #
+  # Within the mailer method, you have access to the following methods:
+  #
+  # * <tt>attachments[]=</tt> - Allows you to add attachments to your email in an intuitive
+  #   manner; <tt>attachments['filename.png'] = File.read('path/to/filename.png')</tt>
+  #
+  # * <tt>attachments.inline[]=</tt> - Allows you to add an inline attachment to your email
+  #   in the same manner as <tt>attachments[]=</tt>
+  #
+  # * <tt>headers[]=</tt> - Allows you to specify any header field in your email such
+  #   as <tt>headers['X-No-Spam'] = 'True'</tt>. Note that declaring a header multiple times
+  #   will add many fields of the same name. Read #headers doc for more information.
+  #
+  # * <tt>headers(hash)</tt> - Allows you to specify multiple headers in your email such
+  #   as <tt>headers({'X-No-Spam' => 'True', 'In-Reply-To' => '1234@message.id'})</tt>
+  #
+  # * <tt>mail</tt> - Allows you to specify email to be sent.
+  #
+  # The hash passed to the mail method allows you to specify any header that a <tt>Mail::Message</tt>
+  # will accept (any valid email header including optional fields).
+  #
+  # The mail method, if not passed a block, will inspect your views and send all the views with
+  # the same name as the method, so the above action would send the +welcome.text.erb+ view
+  # file as well as the +welcome.html.erb+ view file in a +multipart/alternative+ email.
+  #
+  # If you want to explicitly render only certain templates, pass a block:
+  #
+  #   mail(to: user.email) do |format|
+  #     format.text
+  #     format.html
+  #   end
+  #
+  # The block syntax is also useful in providing information specific to a part:
+  #
+  #   mail(to: user.email) do |format|
+  #     format.text(content_transfer_encoding: "base64")
+  #     format.html
+  #   end
+  #
+  # Or even to render a special view:
+  #
+  #   mail(to: user.email) do |format|
+  #     format.text
+  #     format.html { render "some_other_template" }
+  #   end
+  #
+  # = Mailer views
+  #
+  # Like Action Controller, each mailer class has a corresponding view directory in which each
+  # method of the class looks for a template with its name.
+  #
+  # To define a template to be used with a mailer, create an <tt>.erb</tt> file with the same
+  # name as the method in your mailer model. For example, in the mailer defined above, the template at
+  # <tt>app/views/notifier_mailer/welcome.text.erb</tt> would be used to generate the email.
+  #
+  # Variables defined in the methods of your mailer model are accessible as instance variables in their
+  # corresponding view.
+  #
+  # Emails by default are sent in plain text, so a sample view for our model example might look like this:
+  #
+  #   Hi <%= @account.name %>,
+  #   Thanks for joining our service! Please check back often.
+  #
+  # You can even use Action View helpers in these views. For example:
+  #
+  #   You got a new note!
+  #   <%= truncate(@note.body, length: 25) %>
+  #
+  # If you need to access the subject, from or the recipients in the view, you can do that through message object:
+  #
+  #   You got a new note from <%= message.from %>!
+  #   <%= truncate(@note.body, length: 25) %>
+  #
+  #
+  # = Generating URLs
+  #
+  # URLs can be generated in mailer views using <tt>url_for</tt> or named routes. Unlike controllers from
+  # Action Pack, the mailer instance doesn't have any context about the incoming request, so you'll need
+  # to provide all of the details needed to generate a URL.
+  #
+  # When using <tt>url_for</tt> you'll need to provide the <tt>:host</tt>, <tt>:controller</tt>, and <tt>:action</tt>:
+  #
+  #   <%= url_for(host: "example.com", controller: "welcome", action: "greeting") %>
+  #
+  # When using named routes you only need to supply the <tt>:host</tt>:
+  #
+  #   <%= users_url(host: "example.com") %>
+  #
+  # You should use the <tt>named_route_url</tt> style (which generates absolute URLs) and avoid using the
+  # <tt>named_route_path</tt> style (which generates relative URLs), since clients reading the mail will
+  # have no concept of a current URL from which to determine a relative path.
+  #
+  # It is also possible to set a default host that will be used in all mailers by setting the <tt>:host</tt>
+  # option as a configuration option in <tt>config/application.rb</tt>:
+  #
+  #   config.action_mailer.default_url_options = { host: "example.com" }
+  #
+  # You can also define a <tt>default_url_options</tt> method on individual mailers to override these
+  # default settings per-mailer.
+  #
+  # By default when <tt>config.force_ssl</tt> is true, URLs generated for hosts will use the HTTPS protocol.
+  #
+  # = Sending mail
+  #
+  # Once a mailer action and template are defined, you can deliver your message or defer its creation and
+  # delivery for later:
+  #
+  #   NotifierMailer.welcome(User.first).deliver_now # sends the email
+  #   mail = NotifierMailer.welcome(User.first)      # => an ActionMailer::MessageDelivery object
+  #   mail.deliver_now                               # generates and sends the email now
+  #
+  # The <tt>ActionMailer::MessageDelivery</tt> class is a wrapper around a delegate that will call
+  # your method to generate the mail. If you want direct access to the delegator, or <tt>Mail::Message</tt>,
+  # you can call the <tt>message</tt> method on the <tt>ActionMailer::MessageDelivery</tt> object.
+  #
+  #   NotifierMailer.welcome(User.first).message     # => a Mail::Message object
+  #
+  # Action Mailer is nicely integrated with Active Job so you can generate and send emails in the background
+  # (example: outside of the request-response cycle, so the user doesn't have to wait on it):
+  #
+  #   NotifierMailer.welcome(User.first).deliver_later # enqueue the email sending to Active Job
+  #
+  # Note that <tt>deliver_later</tt> will execute your method from the background job.
+  #
+  # You never instantiate your mailer class. Rather, you just call the method you defined on the class itself.
+  # All instance methods are expected to return a message object to be sent.
+  #
+  # = Multipart Emails
+  #
+  # Multipart messages can also be used implicitly because Action Mailer will automatically detect and use
+  # multipart templates, where each template is named after the name of the action, followed by the content
+  # type. Each such detected template will be added to the message, as a separate part.
+  #
+  # For example, if the following templates exist:
+  # * signup_notification.text.erb

+  # * signup_notification.xml.builder
+  # * signup_notification.yml.erb
+  #
+  # Each would be rendered and added as a separate part to the message, with the corresponding content
+  # type. The content type for the entire message is automatically set to <tt>multipart/alternative</tt>,
+  # which indicates that the email contains multiple different representations of the same email
+  # body. The same instance variables defined in the action are passed to all email templates.
+  #
+  # Implicit template rendering is not performed if any attachments or parts have been added to the email.
+  # This means that you'll have to manually add each part to the email and set the content type of the email
+  # to <tt>multipart/alternative</tt>.
+  #
+  # = Attachments
+  #
+  # Sending attachment in emails is easy:
+  #
+  #   class NotifierMailer < ApplicationMailer
+  #     def welcome(recipient)
+  #       attachments['free_book.pdf'] = File.read('path/to/file.pdf')
+  #       mail(to: recipient, subject: "New account information")
+  #     end
+  #   end
+  #
+  # Which will (if it had both a <tt>welcome.text.erb</tt> and <tt>welcome.html.erb</tt>
+  # template in the view directory), send a complete <tt>multipart/mixed</tt> email with two parts,
+  # the first part being a <tt>multipart/alternative</tt> with the text and HTML email parts inside,
+  # and the second being a <tt>application/pdf</tt> with a Base64 encoded copy of the file.pdf book
+  # with the filename +free_book.pdf+.
+  #
+  # If you need to send attachments with no content, you need to create an empty view for it,
+  # or add an empty body parameter like this:
+  #
+  #     class NotifierMailer < ApplicationMailer
+  #       def welcome(recipient)
+  #         attachments['free_book.pdf'] = File.read('path/to/file.pdf')
+  #         mail(to: recipient, subject: "New account information", body: "")
+  #       end
+  #     end
+  #
+  # You can also send attachments with html template, in this case you need to add body, attachments,
+  # and custom content type like this:
+  #
+  #     class NotifierMailer < ApplicationMailer
+  #       def welcome(recipient)
+  #         attachments["free_book.pdf"] = File.read("path/to/file.pdf")
+  #         mail(to: recipient,
+  #              subject: "New account information",
+  #              content_type: "text/html",
+  #              body: "<html><body>Hello there</body></html>")
+  #       end
+  #     end
+  #
+  # = Inline Attachments
+  #
+  # You can also specify that a file should be displayed inline with other HTML. This is useful
+  # if you want to display a corporate logo or a photo.
+  #
+  #   class NotifierMailer < ApplicationMailer
+  #     def welcome(recipient)
+  #       attachments.inline['photo.png'] = File.read('path/to/photo.png')
+  #       mail(to: recipient, subject: "Here is what we look like")
+  #     end
+  #   end
+  #
+  # And then to reference the image in the view, you create a <tt>welcome.html.erb</tt> file and
+  # make a call to +image_tag+ passing in the attachment you want to display and then call
+  # +url+ on the attachment to get the relative content id path for the image source:
+  #
+  #   <h1>Please Don't Cringe</h1>
+  #
+  #   <%= image_tag attachments['photo.png'].url -%>
+  #
+  # As we are using Action View's +image_tag+ method, you can pass in any other options you want:
+  #
+  #   <h1>Please Don't Cringe</h1>
+  #
+  #   <%= image_tag attachments['photo.png'].url, alt: 'Our Photo', class: 'photo' -%>
+  #
+  # = Observing and Intercepting Mails
+  #
+  # Action Mailer provides hooks into the Mail observer and interceptor methods. These allow you to
+  # register classes that are called during the mail delivery life cycle.
+  #
+  # An observer class must implement the <tt>:delivered_email(message)</tt> method which will be
+  # called once for every email sent after the email has been sent.
+  #
+  # An interceptor class must implement the <tt>:delivering_email(message)</tt> method which will be
+  # called before the email is sent, allowing you to make modifications to the email before it hits
+  # the delivery agents. Your class should make any needed modifications directly to the passed
+  # in <tt>Mail::Message</tt> instance.
+  #
+  # = Default Hash
+  #
+  # Action Mailer provides some intelligent defaults for your emails, these are usually specified in a
+  # default method inside the class definition:
+  #
+  #   class NotifierMailer < ApplicationMailer
+  #     default sender: 'system@example.com'
+  #   end
+  #
+  # You can pass in any header value that a <tt>Mail::Message</tt> accepts. Out of the box,
+  # <tt>ActionMailer::Base</tt> sets the following:
+  #
+  # * <tt>mime_version: "1.0"</tt>
+  # * <tt>charset:      "UTF-8"</tt>
+  # * <tt>content_type: "text/plain"</tt>
+  # * <tt>parts_order:  [ "text/plain", "text/enriched", "text/html" ]</tt>
+  #
+  # <tt>parts_order</tt> and <tt>charset</tt> are not actually valid <tt>Mail::Message</tt> header fields,
+  # but Action Mailer translates them appropriately and sets the correct values.
+  #
+  # As you can pass in any header, you need to either quote the header as a string, or pass it in as
+  # an underscored symbol, so the following will work:
+  #
+  #   class NotifierMailer < ApplicationMailer
+  #     default 'Content-Transfer-Encoding' => '7bit',
+  #             content_description: 'This is a description'
+  #   end
+  #
+  # Finally, Action Mailer also supports passing <tt>Proc</tt> and <tt>Lambda</tt> objects into the default hash,
+  # so you can define methods that evaluate as the message is being generated:
+  #
+  #   class NotifierMailer < ApplicationMailer
+  #     default 'X-Special-Header' => Proc.new { my_method }, to: -> { @inviter.email_address }
+  #
+  #     private
+  #       def my_method
+  #         'some complex call'
+  #       end
+  #   end
+  #
+  # Note that the proc/lambda is evaluated right at the start of the mail message generation, so if you
+  # set something in the default hash using a proc, and then set the same thing inside of your
+  # mailer method, it will get overwritten by the mailer method.
+  #
+  # It is also possible to set these default options that will be used in all mailers through
+  # the <tt>default_options=</tt> configuration in <tt>config/application.rb</tt>:
+  #
+  #    config.action_mailer.default_options = { from: "no-reply@example.org" }
+  #
+  # = Callbacks
+  #
+  # You can specify callbacks using before_action and after_action for configuring your messages.
+  # This may be useful, for example, when you want to add default inline attachments for all
+  # messages sent out by a certain mailer class:
+  #
+  #   class NotifierMailer < ApplicationMailer
+  #     before_action :add_inline_attachment!
+  #
+  #     def welcome
+  #       mail
+  #     end
+  #
+  #     private
+  #       def add_inline_attachment!
+  #         attachments.inline["footer.jpg"] = File.read('/path/to/filename.jpg')
+  #       end
+  #   end
+  #
+  # Callbacks in Action Mailer are implemented using
+  # <tt>AbstractController::Callbacks</tt>, so you can define and configure
+  # callbacks in the same manner that you would use callbacks in classes that
+  # inherit from <tt>ActionController::Base</tt>.
+  #
+  # Note that unless you have a specific reason to do so, you should prefer
+  # using <tt>before_action</tt> rather than <tt>after_action</tt> in your
+  # Action Mailer classes so that headers are parsed properly.
+  #
+  # = Previewing emails
+  #
+  # You can preview your email templates visually by adding a mailer preview file to the
+  # <tt>ActionMailer::Base.preview_path</tt>. Since most emails do something interesting
+  # with database data, you'll need to write some scenarios to load messages with fake data:
+  #
+  #   class NotifierMailerPreview < ActionMailer::Preview
+  #     def welcome
+  #       NotifierMailer.welcome(User.first)
+  #     end
+  #   end
+  #
+  # Methods must return a <tt>Mail::Message</tt> object which can be generated by calling the mailer
+  # method without the additional <tt>deliver_now</tt> / <tt>deliver_later</tt>. The location of the
+  # mailer previews directory can be configured using the <tt>preview_path</tt> option which has a default
+  # of <tt>test/mailers/previews</tt>:
+  #
+  #   config.action_mailer.preview_path = "#{Rails.root}/lib/mailer_previews"
+  #
+  # An overview of all previews is accessible at <tt>http://localhost:3000/rails/mailers</tt>
+  # on a running development server instance.
+  #
+  # Previews can also be intercepted in a similar manner as deliveries can be by registering
+  # a preview interceptor that has a <tt>previewing_email</tt> method:
+  #
+  #   class CssInlineStyler
+  #     def self.previewing_email(message)
+  #       # inline CSS styles
+  #     end
+  #   end
+  #
+  #   config.action_mailer.preview_interceptors :css_inline_styler
+  #
+  # Note that interceptors need to be registered both with <tt>register_interceptor</tt>
+  # and <tt>register_preview_interceptor</tt> if they should operate on both sending and
+  # previewing emails.
+  #
+  # = Configuration options
+  #
+  # These options are specified on the class level, like
+  # <tt>ActionMailer::Base.raise_delivery_errors = true</tt>
+  #
+  # * <tt>default_options</tt> - You can pass this in at a class level as well as within the class itself as
+  #   per the above section.
+  #
+  # * <tt>logger</tt> - the logger is used for generating information on the mailing run if available.
+  #   Can be set to +nil+ for no logging. Compatible with both Ruby's own +Logger+ and Log4r loggers.
+  #
+  # * <tt>smtp_settings</tt> - Allows detailed configuration for <tt>:smtp</tt> delivery method:
+  #   * <tt>:address</tt> - Allows you to use a remote mail server. Just change it from its default
+  #     "localhost" setting.
+  #   * <tt>:port</tt> - On the off chance that your mail server doesn't run on port 25, you can change it.
+  #   * <tt>:domain</tt> - If you need to specify a HELO domain, you can do it here.
+  #   * <tt>:user_name</tt> - If your mail server requires authentication, set the username in this setting.
+  #   * <tt>:password</tt> - If your mail server requires authentication, set the password in this setting.
+  #   * <tt>:authentication</tt> - If your mail server requires authentication, you need to specify the
+  #     authentication type here.
+  #     This is a symbol and one of <tt>:plain</tt> (will send the password Base64 encoded), <tt>:login</tt> (will
+  #     send the password Base64 encoded) or <tt>:cram_md5</tt> (combines a Challenge/Response mechanism to exchange
+  #     information and a cryptographic Message Digest 5 algorithm to hash important information)
+  #   * <tt>:enable_starttls_auto</tt> - Detects if STARTTLS is enabled in your SMTP server and starts
+  #     to use it. Defaults to <tt>true</tt>.
+  #   * <tt>:openssl_verify_mode</tt> - When using TLS, you can set how OpenSSL checks the certificate. This is
+  #     really useful if you need to validate a self-signed and/or a wildcard certificate. You can use the name
+  #     of an OpenSSL verify constant (<tt>'none'</tt> or <tt>'peer'</tt>) or directly the constant
+  #     (<tt>OpenSSL::SSL::VERIFY_NONE</tt> or <tt>OpenSSL::SSL::VERIFY_PEER</tt>).
+  #     <tt>:ssl/:tls</tt> Enables the SMTP connection to use SMTP/TLS (SMTPS: SMTP over direct TLS connection)
+  #
+  # * <tt>sendmail_settings</tt> - Allows you to override options for the <tt>:sendmail</tt> delivery method.
+  #   * <tt>:location</tt> - The location of the sendmail executable. Defaults to <tt>/usr/sbin/sendmail</tt>.
+  #   * <tt>:arguments</tt> - The command line arguments. Defaults to <tt>-i</tt> with <tt>-f sender@address</tt>
+  #     added automatically before the message is sent.
+  #
+  # * <tt>file_settings</tt> - Allows you to override options for the <tt>:file</tt> delivery method.
+  #   * <tt>:location</tt> - The directory into which emails will be written. Defaults to the application
+  #     <tt>tmp/mails</tt>.
+  #
+  # * <tt>raise_delivery_errors</tt> - Whether or not errors should be raised if the email fails to be delivered.
+  #
+  # * <tt>delivery_method</tt> - Defines a delivery method. Possible values are <tt>:smtp</tt> (default),
+  #   <tt>:sendmail</tt>, <tt>:test</tt>, and <tt>:file</tt>. Or you may provide a custom delivery method
+  #   object e.g. +MyOwnDeliveryMethodClass+. See the Mail gem documentation on the interface you need to
+  #   implement for a custom delivery agent.
+  #
+  # * <tt>perform_deliveries</tt> - Determines whether emails are actually sent from Action Mailer when you
+  #   call <tt>.deliver</tt> on an email message or on an Action Mailer method. This is on by default but can
+  #   be turned off to aid in functional testing.
+  #
+  # * <tt>deliveries</tt> - Keeps an array of all the emails sent out through the Action Mailer with
+  #   <tt>delivery_method :test</tt>. Most useful for unit and functional testing.
+  #
+  # * <tt>deliver_later_queue_name</tt> - The name of the queue used with <tt>deliver_later</tt>. Defaults to +mailers+.

+    # The main method that creates the message and renders the email templates. There are
+    # two ways to call this method, with a block, or without a block.
+    #
+    # It accepts a headers hash. This hash allows you to specify
+    # the most used headers in an email message, these are:
+    #
+    # * +:subject+ - The subject of the message, if this is omitted, Action Mailer will
+    #   ask the Rails I18n class for a translated +:subject+ in the scope of
+    #   <tt>[mailer_scope, action_name]</tt> or if this is missing, will translate the
+    #   humanized version of the +action_name+
+    # * +:to+ - Who the message is destined for, can be a string of addresses, or an array
+    #   of addresses.
+    # * +:from+ - Who the message is from
+    # * +:cc+ - Who you would like to Carbon-Copy on this email, can be a string of addresses,
+    #   or an array of addresses.
+    # * +:bcc+ - Who you would like to Blind-Carbon-Copy on this email, can be a string of
+    #   addresses, or an array of addresses.
+    # * +:reply_to+ - Who to set the Reply-To header of the email to.
+    # * +:date+ - The date to say the email was sent on.
+    #
+    # You can set default values for any of the above headers (except +:date+)
+    # by using the ::default class method:
+    #
+    #  class Notifier < ActionMailer::Base
+    #    default from: 'no-reply@test.lindsaar.net',
+    #            bcc: 'email_logger@test.lindsaar.net',
+    #            reply_to: 'bounces@test.lindsaar.net'
+    #  end
+    #
+    # If you need other headers not listed above, you can either pass them in
+    # as part of the headers hash or use the <tt>headers['name'] = value</tt>
+    # method.
+    #
+    # When a +:return_path+ is specified as header, that value will be used as
+    # the 'envelope from' address for the Mail message. Setting this is useful
+    # when you want delivery notifications sent to a different address than the
+    # one in +:from+. Mail will actually use the +:return_path+ in preference
+    # to the +:sender+ in preference to the +:from+ field for the 'envelope
+    # from' value.
+    #
+    # If you do not pass a block to the +mail+ method, it will find all
+    # templates in the view paths using by default the mailer name and the
+    # method name that it is being called from, it will then create parts for
+    # each of these templates intelligently, making educated guesses on correct
+    # content type and sequence, and return a fully prepared <tt>Mail::Message</tt>
+    # ready to call <tt>:deliver</tt> on to send.
+    #
+    # For example:
+    #
+    #   class Notifier < ActionMailer::Base
+    #     default from: 'no-reply@test.lindsaar.net'
+    #
+    #     def welcome
+    #       mail(to: 'mikel@test.lindsaar.net')
+    #     end
+    #   end
+    #
+    # Will look for all templates at "app/views/notifier" with name "welcome".
+    # If no welcome template exists, it will raise an ActionView::MissingTemplate error.
+    #
+    # However, those can be customized:
+    #
+    #   mail(template_path: 'notifications', template_name: 'another')
+    #
+    # And now it will look for all templates at "app/views/notifications" with name "another".
+    #
+    # If you do pass a block, you can render specific templates of your choice:
+    #
+    #   mail(to: 'mikel@test.lindsaar.net') do |format|
+    #     format.text
+    #     format.html
+    #   end
+    #
+    # You can even render plain text directly without using a template:
+    #
+    #   mail(to: 'mikel@test.lindsaar.net') do |format|
+    #     format.text { render plain: "Hello Mikel!" }
+    #     format.html { render html: "<h1>Hello Mikel!</h1>".html_safe }
+    #   end
+    #
+    # Which will render a +multipart/alternative+ email with +text/plain+ and
+    # +text/html+ parts.
+    #
+    # The block syntax also allows you to customize the part headers if desired:
+    #
+    #   mail(to: 'mikel@test.lindsaar.net') do |format|
+    #     format.text(content_transfer_encoding: "base64")
+    #     format.html
+    #   end

+Description:
+============
+    Stubs out a new mailer and its views. Passes the mailer name, either
+    CamelCased or under_scored, and an optional list of emails as arguments.
+
+    This generates a mailer class in app/mailers and invokes your template
+    engine and test framework generators.
+
+Example:
+========
+    rails generate mailer Notifications signup forgot_password invoice
+
+    creates a Notifications mailer class, views, and test:
+        Mailer:     app/mailers/notifications_mailer.rb
+        Views:      app/views/notifications_mailer/signup.text.erb [...]

+## Rails 5.1.0 (April 27, 2017) ##
+
+*   Raise exception when calling `to_h` and `to_hash` in an unpermitted Parameters.
+
+    Before we returned either an empty hash or only the always permitted parameters
+    (`:controller` and `:action` by default).
+
+    The previous behavior was dangerous because in order to get the attributes users
+    usually fallback to use `to_unsafe_h that` could potentially introduce security issues.
+
+    *Rafael Mendonça França*
+
+*   Deprecate `config.action_controller.raise_on_unfiltered_parameters`.
+
+    This option has no effect in Rails 5.1.
+
+    *Rafael Mendonça França*
+
+*   Use more specific check for :format in route path
+
+    The current check for whether to add an optional format to the path is very lax
+    and will match things like `:format_id` where there are nested resources, e.g:
+
+    ``` ruby
+    resources :formats do
+      resources :items
+    end
+    ```
+
+    Fix this by using a more restrictive regex pattern that looks for the patterns
+    `(.:format)`, `.:format` or `/` at the end of the path. Note that we need to
+    allow for multiple closing parenthesis since the route may be of this form:
+
+    ``` ruby
+    get "/books(/:action(.:format))", controller: "books"
+    ```
+
+    This probably isn't what's intended since it means that the default index action
+    route doesn't support a format but we have a test for it so we need to allow it.
+
+    Fixes #28517.
+
+    *Andrew White*
+
+*   Add `action_controller_api` and `action_controller_base` load hooks to be called in `ActiveSupport.on_load`
+
+    `ActionController::Base` and `ActionController::API` have differing implementations. This means that
+    the one umbrella hook `action_controller` is not able to address certain situations where a method
+    may not exist in a certain implementation.
+
+    This is fixed by adding two new hooks so you can target `ActionController::Base` vs `ActionController::API`
+
+    Fixes #27013.
+
+    *Julian Nadeau*
+
+*   Don't include default headers in `ActionController::Metal` responses
+
+    The commit e16afe6 introduced an unintentional change of behavior where the default
+    headers were included in responses from `ActionController::Metal` based controllers.
+    This is now reverted to the previous behavior of having no default headers.
+
+    Fixes #25820.
+
+    *Jon Moss*
+
+*   Fix `NameError` raised in `ActionController::Renderer#with_defaults`
+
+    *Hiroyuki Ishii*
+
+*   Added `#reverse_merge` and `#reverse_merge!` methods to `ActionController::Parameters`
+
+    *Edouard Chin*, *Mitsutaka Mimura*
+
+*   Fix malformed URLS when using `ApplicationController.renderer`
+
+    The Rack environment variable `rack.url_scheme` was not being set so `scheme` was
+    returning `nil`. This caused URLs to be malformed with the default settings.
+    Fix this by setting `rack.url_scheme` when the environment is normalized.
+
+    Fixes #28151.
+
+    *George Vrettos*
+
+*   Commit flash changes when using a redirect route.
+
+    Fixes #27992.
+
+    *Andrew White*
+
+*   Prefer `remove_method` over `undef_method` when reloading routes
+
+    When `undef_method` is used it prevents access to other implementations of that
+    url helper in the ancestor chain so use `remove_method` instead to restore access.
+
+    *Andrew White*
+
+*   Add the `resolve` method to the routing DSL
+
+    This new method allows customization of the polymorphic mapping of models:
+
+    ``` ruby
+    resource :basket
+    resolve("Basket") { [:basket] }
+    ```
+
+    ``` erb
+    <%= form_for @basket do |form| %>
+    <!-- basket form -->
+    <% end %>
+    ```
+
+    This generates the correct singular URL for the form instead of the default
+    resources member url, e.g. `/basket` vs. `/basket/:id`.
+
+    Fixes #1769.
+
+    *Andrew White*
+
+*   Add the `direct` method to the routing DSL
+
+    This new method allows creation of custom url helpers, e.g:
+
+    ``` ruby
+    direct(:apple) { "http://www.apple.com" }
+
+    >> apple_url
+    => "http://www.apple.com"
+    ```
+
+    This has the advantage of being available everywhere url helpers are available
+    unlike custom url helpers defined in helper modules, etc.

+
+    *Kir Shatrov*
+
+*   Fix nested multiple roots
+
+    The PR #20940 enabled the use of multiple roots with different constraints
+    at the top level but unfortunately didn't work when those roots were inside
+    a namespace and also broke the use of root inside a namespace after a top
+    level root was defined because the check for the existence of the named route
+    used the global :root name and not the namespaced name.
+
+    This is fixed by using the name_for_action method to expand the :root name to
+    the full namespaced name. We can pass nil for the second argument as we're not
+    dealing with resource definitions so don't need to handle the cases for edit
+    and new routes.
+
+    Fixes #26148.
+
+    *Ryo Hashimoto*, *Andrew White*
+
+*   Include the content of the flash in the auto-generated etag. This solves the following problem:
+
+      1. POST /messages
+      2. redirect_to messages_url, notice: 'Message was created'
+      3. GET /messages/1
+      4. GET /messages
+
+      Step 4 would before still include the flash message, even though it's no longer relevant,
+      because the etag cache was recorded with the flash in place and didn't change when it was gone.
+
+    *DHH*
+
+*   SSL: Changes redirect behavior for all non-GET and non-HEAD requests
+    (like POST/PUT/PATCH etc) to `http://` resources to redirect to `https://`
+    with a [307 status code](http://tools.ietf.org/html/rfc7231#section-6.4.7) instead of [301 status code](http://tools.ietf.org/html/rfc7231#section-6.4.2).
+
+    307 status code instructs the HTTP clients to preserve the original
+    request method while redirecting. It has been part of HTTP RFC since
+    1999 and is implemented/recognized by most (if not all) user agents.
+
+        # Before
+        POST http://example.com/articles (i.e. ArticlesContoller#create)
+        redirects to
+        GET https://example.com/articles (i.e. ArticlesContoller#index)
+
+        # After
+        POST http://example.com/articles (i.e. ArticlesContoller#create)
+        redirects to
+        POST https://example.com/articles (i.e. ArticlesContoller#create)
+
+    *Chirag Singhal*
+
+*   Add `:as` option to `ActionController:TestCase#process` and related methods.
+
+    Specifying `as: mime_type` allows the `CONTENT_TYPE` header to be specified
+    in controller tests without manually doing this through `@request.headers['CONTENT_TYPE']`.
+
+    *Everest Stefan Munro-Zeisberger*
+
+*   Show cache hits and misses when rendering partials.
+
+    Partials using the `cache` helper will show whether a render hit or missed
+    the cache:
+
+    ```
+    Rendered messages/_message.html.erb in 1.2 ms [cache hit]
+    Rendered recordings/threads/_thread.html.erb in 1.5 ms [cache miss]
+    ```
+
+    This removes the need for the old fragment cache logging:
+
+    ```
+    Read fragment views/v1/2914079/v1/2914079/recordings/70182313-20160225015037000000/d0bdf2974e1ef6d31685c3b392ad0b74 (0.6ms)
+    Rendered messages/_message.html.erb in 1.2 ms [cache hit]
+    Write fragment views/v1/2914079/v1/2914079/recordings/70182313-20160225015037000000/3b4e249ac9d168c617e32e84b99218b5 (1.1ms)
+    Rendered recordings/threads/_thread.html.erb in 1.5 ms [cache miss]
+    ```
+
+    Though that full output can be reenabled with
+    `config.action_controller.enable_fragment_cache_logging = true`.
+
+    *Stan Lo*
+
+*   Don't override the `Accept` header in integration tests when called with `xhr: true`.
+
+    Fixes #25859.
+
+    *David Chen*
+
+*   Fix `defaults` option for root route.
+
+    A regression from some refactoring for the 5.0 release, this change
+    fixes the use of `defaults` (default parameters) in the `root` routing method.
+
+    *Chris Arcand*
+
+*   Check `request.path_parameters` encoding at the point they're set.
+
+    Check for any non-UTF8 characters in path parameters at the point they're
+    set in `env`. Previously they were checked for when used to get a controller
+    class, but this meant routes that went directly to a Rack app, or skipped
+    controller instantiation for some other reason, had to defend against
+    non-UTF8 characters themselves.
+
+    *Grey Baker*
+
+*   Don't raise `ActionController::UnknownHttpMethod` from `ActionDispatch::Static`.
+
+    Pass `Rack::Request` objects to `ActionDispatch::FileHandler` to avoid it
+    raising `ActionController::UnknownHttpMethod`. If an unknown method is
+    passed, it should pass exception higher in the stack instead, once we've had a
+    chance to define exception handling behaviour.
+
+    *Grey Baker*
+
+*   Handle `Rack::QueryParser` errors in `ActionDispatch::ExceptionWrapper`.
+
+    Updated `ActionDispatch::ExceptionWrapper` to handle the Rack 2.0 namespace
+    for `ParameterTypeError` and `InvalidParameterError` errors.
+

+= Action Pack -- From request to response
+
+Action Pack is a framework for handling and responding to web requests. It
+provides mechanisms for *routing* (mapping request URLs to actions), defining
+*controllers* that implement actions, and generating responses by rendering
+*views*, which are templates of various formats. In short, Action Pack
+provides the view and controller layers in the MVC paradigm.
+
+It consists of several modules:
+
+* Action Dispatch, which parses information about the web request, handles
+  routing as defined by the user, and does advanced processing related to HTTP
+  such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
+  handling HTTP caching logic, cookies and sessions.
+
+* Action Controller, which provides a base controller class that can be
+  subclassed to implement filters and actions to handle requests. The result
+  of an action is typically content generated from views.
+
+With the Ruby on Rails framework, users only directly interface with the
+Action Controller module. Necessary Action Dispatch functionality is activated
+by default and Action View rendering is implicitly triggered by Action
+Controller. However, these modules are designed to function on their own and
+can be used outside of Rails.
+
+
+== Download and installation
+
+The latest version of Action Pack can be installed with RubyGems:
+
+  $ gem install actionpack

+module ActionController
+  # API Controller is a lightweight version of <tt>ActionController::Base</tt>,
+  # created for applications that don't require all functionalities that a complete
+  # \Rails controller provides, allowing you to create controllers with just the
+  # features that you need for API only applications.
+  #
+  # An API Controller is different from a normal controller in the sense that
+  # by default it doesn't include a number of features that are usually required
+  # by browser access only: layouts and templates rendering, cookies, sessions,
+  # flash, assets, and so on. This makes the entire controller stack thinner,
+  # suitable for API applications. It doesn't mean you won't have such
+  # features if you need them: they're all available for you to include in
+  # your application, they're just not part of the default API controller stack.
+  #
+  # Normally, +ApplicationController+ is the only controller that inherits from
+  # <tt>ActionController::API</tt>. All other controllers in turn inherit from
+  # +ApplicationController+.
+  #
+  # A sample controller could look like this:
+  #
+  #   class PostsController < ApplicationController
+  #     def index
+  #       posts = Post.all
+  #       render json: posts
+  #     end
+  #   end
+  #
+  # Request, response, and parameters objects all work the exact same way as
+  # <tt>ActionController::Base</tt>.
+  #
+  # == Renders
+  #
+  # The default API Controller stack includes all renderers, which means you
+  # can use <tt>render :json</tt> and brothers freely in your controllers. Keep
+  # in mind that templates are not going to be rendered, so you need to ensure
+  # your controller is calling either <tt>render</tt> or <tt>redirect_to</tt> in
+  # all actions, otherwise it will return 204 No Content.
+  #
+  #   def show
+  #     post = Post.find(params[:id])
+  #     render json: post
+  #   end
+  #
+  # == Redirects
+  #
+  # Redirects are used to move from one action to another. You can use the
+  # <tt>redirect_to</tt> method in your controllers in the same way as in
+  # <tt>ActionController::Base</tt>. For example:
+  #
+  #   def create
+  #     redirect_to root_url and return if not_authorized?
+  #     # do stuff here
+  #   end
+  #
+  # == Adding New Behavior
+  #
+  # In some scenarios you may want to add back some functionality provided by
