AwesomeCo
AwesomeCo is a test data seeding harness, that can seed test data into a user or group namespace.
AwesomeCo uses FactoryBot in the backend which makes maintenance extremely easy. When a Model is changed, FactoryBot will already be reflected to account for the change.
Docker Setup
GDK Setup
$ gdk start db
ok: run: services/postgresql: (pid n) 0s, normally down
ok: run: services/redis: (pid n) 74s, normally down
$ bundle install
Bundle complete!
$ bundle exec rake db:migrate
main: migrated
ci: migrated
Run
The ee:gitlab:seed:awesome_co
Rake task takes two arguments. :name
and :namespace_id
.
$ bundle exec rake "ee:gitlab:seed:awesome_co[awesome_co,1]"
Seeding AwesomeCo for Administrator
:name
Where :name
is the name of the AwesomeCo. (This will reflect .rb files located in db/seeds/awesome_co/*.rb)
:namespace_id
Where :namespace_id
is the ID of the User or Group Namespace
List of Awesome Companies
Each company (i.e. test data template) is represented as a Ruby file (.rb) in db/seeds/awesome_co
.
AwesomeCo (db/seeds/awesome_co/awesome_co.rb)
$ bundle exec rake "ee:gitlab:seed:awesome_co[awesome_co,:namespace_id]"
Seeding AwesomeCo for :namespace_id
AwesomeCo is an automated seeding of this demo repository.
Develop
AwesomeCo seeding uses FactoryBot definitions from spec/factories
which ...
- Saves time on development
- Are easy-to-read
- Are easy to maintain
- Do not rely on an API that may change in the future
- Are always up-to-date
- Execute on the lowest-level (
ActiveRecord
) possible to create data as quickly as possible
From the FactoryBot README :
factory_bot
is a fixtures replacement with a straightforward definition syntax, support for multiple build strategies (saved instances, unsaved instances, attribute hashes, and stubbed objects), and support for multiple factories for the same class, including factory inheritance
Factories reside in spec/factories/*
and are fixtures for Rails models found in app/models/*
. For example, For a model named app/models/issue.rb
, the factory will
be named spec/factories/issues.rb
. For a model named app/models/project.rb
, the factory will be named app/models/projects.rb
.
Taxonomy of a Factory
Factories consist of three main parts - the Name of the factory, the Traits and the Attributes.
Given: create(:iteration, :with_title, :current, title: 'My Iteration')
:iteration | This is the Name of the factory. The file name will be the plural form of this Name and reside under either spec/factories/iterations.rb or ee/spec/factories/iterations.rb . |
:with_title | This is a Trait of the factory. See how it's defined. |
:current | This is a Trait of the factory. See how it's defined. |
title: 'My Iteration' | This is an Attribute of the factory that will be passed to the Model for creation. |
Examples
In these examples, you will see an instance variable @owner
. This is the root
user (User.first
).
Create a Group
my_group = create(:group, name: 'My Group', path: 'my-group-path')
Create a Project
# create a Project belonging to a Group
my_project = create(:project, :public, name: 'My Project', namespace: my_group, creator: @owner)
Create an Issue
# create an Issue belonging to a Project
my_issue = create(:issue, title: 'My Issue', project: my_project, weight: 2)
Create an Iteration
# create an Iteration under a Group
my_iteration = create(:iteration, :with_title, :current, title: 'My Iteration', group: my_group)
Frequently encountered issues
ActiveRecord::RecordInvalid: Validation failed: Email has already been taken, Username has already been taken
This is because, by default, our factories are written to backfill any data that is missing. For instance, when a project is created, the project must have somebody that created it. If the owner is not specified, the factory attempts to create it.
How to fix
Check the respective Factory to find out what key is required. Usually :author
or :owner
.
# This throws ActiveRecord::RecordInvalid
create(:project, name: 'Throws Error', namespace: create(:group, name: 'Some Group'))
# Specify the user where @owner is a [User] record
create(:project, name: 'No longer throws error', owner: @owner, namespace: create(:group, name: 'Some Group'))
create(:epic, group: create(:group), author: @owner)
parsing id "my id" as "my_id"
id is invalid
Given that non-Ruby parsers parse IDs as Ruby Objects, the naming conventions of Ruby must be followed when specifying an ID.
Examples of invalid IDs:
- IDs that start with a number
- IDs that have special characters (-, !, $, @, `, =, <, >, ;, :)
ActiveRecord::AssociationTypeMismatch: Model expected, got ... which is an instance of String
This is currently a limitation for the seeder.
See the issue for allowing parsing of raw Ruby objects.
YAML Factories
Generator to generate n amount of records
Group Labels
group_labels:
# Group Label with Name and a Color
- name: Group Label 1
group_id: <%= @group.id %>
color: "#FF0000"
Group Milestones
group_milestones:
# Past Milestone
- name: Past Milestone
group_id: <%= @group.id %>
group:
start_date: <%= 1.month.ago %>
due_date: <%= 1.day.ago %>
# Ongoing Milestone
- name: Ongoing Milestone
group_id: <%= @group.id %>
group:
start_date: <%= 1.day.ago %>
due_date: <%= 1.month.from_now %>
# Future Milestone
- name: Ongoing Milestone
group_id: <%= @group.id %>
group:
start_date: <%= 1.month.from_now %>
due_date: <%= 2.months.from_now %>
Quirks
- You must specify
group:
and have it be empty. This is because the Milestones factory will manipulate the factory in anafter(:build)
. If this is not present, the Milestone will not be associated properly with the Group.
Epics
epics:
# Simple Epic
- title: Simple Epic
group_id: <%= @group.id %>
author_id: <%= @owner.id %>
# Epic with detailed Markdown description
- title: Detailed Epic
group_id: <%= @group.id %>
author_id: <%= @owner.id %>
description: |
# Markdown
**Description**
# Epic with dates
- title: Epic with dates
group_id: <%= @group.id %>
author_id: <%= @owner.id %>
start_date: <%= 1.day.ago %>
due_date: <%= 1.month.from_now %>
Variables
Each created factory can be assigned an identifier to be used in future seeding.
You can specify an ID for any created factory that you may use later in the seed file.
Specify a variable
You may pass an _id
attribute on any factory to refer back to it later in non-Ruby parsers.
Variables are under the factory definitions that they reside in.
---
group_labels:
- _id: my_label #=> group_labels.my_label
projects:
- _id: my_project #=> projects.my_project
Variables:
NOTE: It is not advised, but you may specify variables with spaces. These variables may be referred back to with underscores.
Referencing a variable
Given a YAML seed file:
---
group_labels:
- _id: my_group_label #=> group_labels.my_group_label
name: My Group Label
color: "#FF0000"
- _id: my_other_group_label #=> group_labels.my_other_group_label
color: <%= group_labels.my_group_label.color %>
projects:
- _id: my_project #=> projects.my_project
name: My Project
When referring to a variable, the variable refers to the already seeded models. In other words, the model's id
attribute will
be populated.
