Yes, you need a view if you are going to display the @applications. Create a new file app/views/applications/list.html.erb if you are using erb of course.

You also need to add a route to this list action if you haven't done that already. I'm assuming a get request as your code only shows retrieval of Application. In your config/routes.rb add the following lines: 

resources :applications do 
  collection do 
    get :list
  end
end

Once these are done you'll have /applications/list path which will execute the list action of your ApplicationsController and the view list.html.erb.

Great answer. Very helpful =) But now, I want to know if i did the scaffolding, I have this in my routes "resources :applications", and when i use that code you told me I got that error: "undefined method `collections'". Am i doing something wrong? –  Cris Towi Jul 30 '13 at 4:44
    
@CrisTowi, sorry that was a typo. It should have been collection, not collections. Corrected my answer as well. –  vee Jul 30 '13 at 4:45
