title: dots in URL routes with namespace rails 3.1
body: <p>I have this in <strong>routes.rb</strong></p>
  
  <pre><code>root :to =&gt; "posts#index"
  
    devise_for :users,  :controllers =&gt; { :omniauth_callbacks =&gt; "users/omniauth_callbacks" }
  
    resources :users, :only =&gt; :show
  
    resources :boards 
  
    resources :posts do
    resources :comments
    end 
  
  namespace :users do
   resources :posts do
    get :posts, :on =&gt; :member
   end
   resources :boards do  
    get :boards, :on =&gt; :member
   end  
  end      
  </code></pre>
  
  <p>rake routes:</p>
  
  <pre><code>  boards_users_board GET    /users/boards/:id/boards(.:format)        {:action=&gt;"boards", :controller=&gt;"users/boards"}
          users_boards GET    /users/boards(.:format)                   {:action=&gt;"index", :controller=&gt;"users/boards"}
                      POST    /users/boards(.:format)                   {:action=&gt;"create", :controller=&gt;"users/boards"}
       new_users_board GET    /users/boards/new(.:format)               {:action=&gt;"new", :controller=&gt;"users/boards"}
      edit_users_board GET    /users/boards/:id/edit(.:format)          {:action=&gt;"edit", :controller=&gt;"users/boards"}
           users_board GET    /users/boards/:id(.:format)               {:action=&gt;"show", :controller=&gt;"users/boards"}
  </code></pre>
  
  <p>If I put this link with 2 parameters:</p>
  
  <pre><code>&lt;% @posts.each do |post| %&gt;
     &lt;%= link_to post.board.name, users_board_path(post.user, post.board) %&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>I get the next url with a dot:</p>
  
  <p><a href="http://localhost:3000/users/boards/hyperrjas.board-2" rel="nofollow">http://localhost:3000/users/boards/hyperrjas.board-2</a></p>
  
  <ul>
  <li><strong>hyperrjas is the user_id that I have put with slug :username.</strong></li>
  <li>I use namespace because are nested resources and I have a panel for users.</li>
  </ul>
  
  <p><strong>My question is: How can I change the dot for slash / in my generated url?</strong> should look and work as follows:</p>
  
  <p><a href="http://localhost:3000/users/boards/hyperrjas/board-2" rel="nofollow">http://localhost:3000/users/boards/hyperrjas/board-2</a></p>
