Question

in routing

     resources :departments do
       resources :buildings do
         resources :halls do
       end
       resources :chairs do
         resources :buildings do
           resources :halls do
         end
       end
     end

I want to share the same views of buildings and halls between chairs and departments. And I am thinking to create url’s in views this way:

link_to "Show", [@department, @chair, @building, @hall].compact

If @chair doesn’t exist, it’s gonna be nil, so upper link will generate:

link_to "Show", [@department, @building, @hall]

If @chair exist:

link_to "Show", [@department, @chair, @building, @hall]

My question is: How to create this way url’s to edit, or new action? Or maybe there exist better solution for this problem with this kind of nested resources?

Answer 1

You can stick a symbol in the array as well. So something like this:

link_to "Edit", [:edit, @department, @chair, @building, @hall]
