Routes

Using :path to specify the URLs

# config/routes.rb
namespace :api, defaults: {format: 'json'} do
  namespace :v1 do
    resources :posts, only: :show do
      resources :post_comments, path: 'comments'
    end
  end
end

# $rake routes
    api_v1_post_post_comments GET    /api/v1/posts/:post_id/comments(.:format)          api/v1/post_comments#index {:format=>"json"}
                              POST   /api/v1/posts/:post_id/comments(.:format)          api/v1/post_comments#create {:format=>"json"}
 new_api_v1_post_post_comment GET    /api/v1/posts/:post_id/comments/new(.:format)      api/v1/post_comments#new {:format=>"json"}
edit_api_v1_post_post_comment GET    /api/v1/posts/:post_id/comments/:id/edit(.:format) api/v1/post_comments#edit {:format=>"json"}
     api_v1_post_post_comment GET    /api/v1/posts/:post_id/comments/:id(.:format)      api/v1/post_comments#show {:format=>"json"}
                              PATCH  /api/v1/posts/:post_id/comments/:id(.:format)      api/v1/post_comments#update {:format=>"json"}
                              PUT    /api/v1/posts/:post_id/comments/:id(.:format)      api/v1/post_comments#update {:format=>"json"}
                              DELETE /api/v1/posts/:post_id/comments/:id(.:format)      api/v1/post_comments#destroy {:format=>"json"}
                  api_v1_post GET    /api/v1/posts/:id(.:format)                        api/v1/posts#show {:format=>"json"}

Show routes info

Display all routes

$ rake routes

Display part of routes using grep, good for wanting to list routes just match part of urls

$ rake routes | grep '/some_specific_url_part/'

Alternately, you could start your rails server ($rails s) and visit http://localhost:3000/rails/info/routes to see the all routes

Display restricted/specific routes

$ rake routes CONTROLLER=folder_name/controller_name

# example:
# Show Test::TestsController routes
$ rake routes CONTROLLER=test/tests

Convert routes info into an array

routes = Rails.application.routes.routes.to_a
