= 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.
