How to name a route in rails

Question

I have some routes looking like this :

match \'hotels/:action(/:id)\', :controller => \'hotel\', :action => /[a-z]+/i, :id => /[0-9]+/i

Answer 1

A lot has changed in the world of Rails since 2011 - this is how you would accomplish the same goal in Rails 4.

resources :hotels do
  member do
    post 'dislike'
    post 'like'
  end
end

The resulting routes:

   dislike_hotel POST     /hotels/:id/dislike(.:format)   hotels#dislike
      like_hotel POST     /hotels/:id/like(.:format)      hotels#like
          hotels GET      /hotels(.:format)               hotels#index
                 POST     /hotels(.:format)               hotels#create
       new_hotel GET      /hotels/new(.:format)           hotels#new
      edit_hotel GET      /hotels/:id/edit(.:format)      hotels#edit
           hotel GET      /hotels/:id(.:format)           hotels#show
                 PATCH    /hotels/:id(.:format)           hotels#update
                 PUT      /hotels/:id(.:format)           hotels#update
                 DELETE   /hotels/:id(.:format)           hotels#destro

Notice thats rails prefixes instead of postfixes the action - dislike_hotel_path not hotels_dislike.

From the routing guide:

3.6 Naming Routes

You can specify a name for any route using the :as option.

match 'exit' => 'sessions#destroy', :as => :logout

So, in your case, that would be:

match 'hotels/:action(/:id)', :controller => 'hotel', :action => /[a-z]+/i, :id => /[0-9]+/i
match 'hotels/dislike(/:id)', :controller => 'hotel', :id => /[0-9]+/i, :as => :hotels_dislike
match 'hotels/like(/:id)', :controller => 'hotel', :id => /[0-9]+/i, :as => :hotels_like

I don't think there's a way to do this dynamically (so you have to define one route for each action, basically). However, you can just define a couple of routes (like above) for the most used actions, and just use hotels_path :action => :really_like for more uncommon actions.
