API Endpoints for gitlab-org/gitlab-ce-

This documentation serves as an in-depth guide for developers on how to identify and understand the routes defined in the GitLab CE codebase. Routes in a Ruby on Rails application like GitLab CE are defined in the routing files, allowing developers to map HTTP requests to controller actions.

Overview of Routing in GitLab CE

In GitLab CE, routing is primarily defined in the config/routes.rb file and any additional routes can be found in sub-files organized within the config/routes directory. The structure of these routes determines how users and applications interact with various API endpoints, web pages, and resources within GitLab.

Analyzing Routes

To analyze the routes in GitLab CE, you can use the built-in Rails command:

rails routes

This command provides a comprehensive list of all routes defined in the application, including HTTP verbs (GET, POST, PATCH, DELETE), route paths, and the corresponding controller actions.

Example Route Definitions

Below are examples of route definitions found in the GitLab CE codebase, along with explanations.

1. Basic Route Definition

   The following example demonstrates a basic route definition in config/routes.rb:

   get 'users/:id', to: 'users#show'
   
   

   This defines a GET route for accessing a user by their ID, pointing to the show action of the UsersController.

2. Nested Routes

   GitLab CE uses nested routes for related resources. An example of this can be seen in the following definition:

   resources :projects do
   
   resources :issues
   
   end
   
   

   Here, issues are nested within projects, meaning that issues are directly associated with a specific project. The URL structure becomes /projects/:project_id/issues.

3. API Routes

   The API routes are typically defined in the api namespace. Here’s an example definition for an API route:

   namespace :api do
   
   resources :projects, only: [:index, :show]
   
   end
   
   

   This code defines routes for the projects resource, making it accessible via the /api/projects endpoint, with support for the index and show actions.

4. Custom Routes

   Custom routes can also be created to handle specific actions not following the conventional RESTful pattern:

   post 'upload', to: 'uploads#create'
   
   

   In this example, a POST request to /upload is routed to the create action of the UploadsController.

Inspecting Route Details

To inspect route details further, developers can use the Rails console, which allows access to route information programmatically. For instance, to find the controller and action for a specific route, you could execute:

Rails.application.routes.routes.recognize_path('/users/1')

This will return a hash containing the controller and action for the requested path.

Source of Information

The examples and explanations provided in this documentation are derived directly from the GitLab CE codebase, specifically referencing the contents of the routing files such as config/routes.rb and related directory files.

For further exploration, developers are encouraged to review the routing configurations directly in the repository where the definition of all routes lives continuously evolves with new features and adjustments based on ongoing development efforts.
