Single custom param name in routes for nested resources Rails 4.1

Question

I have question about param name for nested resources in rails routes For example i have:

resources :controller1, param: :controller_id do
  resources :controller2
end

and i have routes:

controller1/:controller_id/
...
controller1/:controller_controller_id/controller2/...
...

I want single :controller_id for controller1 I know it's looks bad, but How do this? Thanks!

Answer 1

how about this:

resources :controller1, param: :controller_id do
  member do
    resources :controller2
  end
end

will generate

GET    /controller1/:controller_id
GET    /controller1/:controller_id/controller2
GET    /controller1/:controller_id/controller2/:id
...
