Question

In Ruby on Rails, is there a way to add another RESTful action to the base URL of a plural resource? I’m looking for something like this:

resources :groups do
  resources :users do
    put on: :base, to: 'users#update_all'
  end
end

Which would generate the route: [PUT] groups/:group_id/users => users#update_all

I’ve already tried doing this:

resources :groups do
  resources :users
  put 'users', on: :member, to: 'users#update_all'
end

But that doesn’t preserve the value of params[:group_id] in the controller.

Answer 1

resources :users do
  collection do
    put '' => 'users#update_all' ## PUT /users
  end
end

UPDATE

It would be recommended to do this though:

resources :users do
  collection do
    put 'update_all' ## PUT /users/update_all
  end
end

Both route to the update_all action of the users controller.
