Routes • Mastodon documentation

Explanation of routes

Mastodon uses Ruby on Rails, which defines its router configuration at config/routes.rb. You may view the Ruby on Rails routing guide for more detailed information, but this page will explain the basics of how Mastodon handles routing.

How routes are constructed

namespace is a prefix for routes mapped to a certain controller directory. resources are mapped to controllers within that namespace directory. scope passes to the module’s controller. For example, consider the following abbreviated code:

namespace :api do
    namespace :v1 do
        resources :statuses, only [:create, :show, :destroy] do
            scope module: :statuses do
                resource :favourite, only: :create
                resource :unfavourite, to: 'favourites#destroy'
                member do
                    get :context
                end
            end
        end
    end
end

config/routes.rb excerpt

The first available resource is :statuses, which is nested under the :api and :v1 namespaces. Thus, the resulting HTTP route will be /api/v1/statuses. The only defines certain allowed methods, which are to be defined in the controller at app/controllers/api/v1/statuses_controller.rb.

Within /api/v1/statuses, there is a scope for a module :statuses, where additional resources are defined. The controllers for these resources live in app/controllers/api/v1/statuses/. For example, :favourite will be handled by the #create action within app/controllers/api/v1/statuses/favourites_controller.rb and :unfavourite will be handled within the same controller, but by the #destroy action.

There is also a custom method defined for any member within this scope, or in other words, for any status to be controlled by app/controllers/api/v1/statuses_controller.rb, which is mapped to GET /api/v1/statuses/:id/context and handled by the :context action defined within that controller.

Available methods

:index

Maps to HTTP GET, for a list. Handled by the #index action in a controller.

:show

Maps to HTTP GET, for a single view. Handled by the #show action in a controller.

:create

Maps to HTTP POST. Handled by the #create action in a controller.

:update

Maps to HTTP PUT. Handled by the #update action in a controller.

:destroy

Maps to HTTP DELETE. Handled by the #destroy action in a controller.
