Here's the output for <code>rake routes</code>:</p> <pre><code> things GET /things(.:format) {:action=>"index", :controller=>"things"} POST /things(.:format) {:action=>"create", :controller=>"things"} new_thing GET /things/new(.:format) {:action=>"new", :controller=>"things"} edit_thing GET /things/:id/edit(.:format) {:action=>"edit", :controller=>"things"} thing GET /things/:id(.:format) {:action=>"show", :controller=>"things"} PUT /things/:id(.:format) {:action=>"update", :controller=>"things"} DELETE /things/:id(.:format) {:action=>"destroy", :controller=>"things"} </code></pre> <p>It sounds like you want something more like this:</p> <pre><code>create_things POST /things/new(.:format) {:action=>"create", :controller=>"things"} things GET /things(.:format) {:action=>"index", :controller=>"things"} new_thing GET /things/new(.:format) {:action=>"new", :controller=>"things"} edit_thing GET /things/:id/edit(.:format) {:action=>"edit", :controller=>"things"} thing GET /things/:id(.:format) {:action=>"show", :controller=>"things"} PUT /things/:id(.:format) {:action=>"update", :controller=>"things"} DELETE /things/:id(.:format) {:action=>"destroy", :controller=>"things"} </code></pre> <p>Although not recommended, you can get this result with the following route:</p> <pre><code>resources :things, :except => [ :create ] do post "create" => "things#create", :as => :create, :path => 'new', :on => :collection end </code></pre> <p>You would also need to modify your forms to make them POST to the correct path.</p>
