copied!<p>NEW EDITING</p> <p>With <code>resources :cases</code> in the <code>routes.rb</code> all these routing helpers work as expected (c is an instance of the model Case):</p> <pre><code>cases_path # Index action new_case_path # New action case_path(c) # Show action edit_case_path(c) # Edit action </code></pre> <p>Changing <code>routes.rb</code> to this:</p> <pre><code>scope "/:area" do resources :cases end </code></pre> <p>two routing helpers fail (see error below):</p> <pre><code>cases_path # OK new_case_path # OK case_path(c) # Fail edit_case_path(c) # Fail </code></pre> <p>To make it works I need to change the last two helpers in:</p> <pre><code>cases_path # OK new_case_path # OK case_path(c, :area => params[:area]) # OK edit_case_path(c, :area => params[:area]) # OK </code></pre> <p>Why there is no need to give :area to the first two helpers and there is a need for the second two? It makes the code confusing...</p> <p>OLD QUESTION</p> <p>Initially I had this routes.rb:</p> <pre><code>resources :cases </code></pre> <p>and I could generate links of this type</p> <pre><code>example.com/cases/3 </code></pre> <p>to show the case with ID = 3 with:</p> <pre><code>link_to("Show this case", @case) </code></pre> <p>Then I modified routes.rb to:</p> <pre><code>scope "/:area" do resources :cases end </code></pre> <p>end the link_to above give me the error</p> <pre><code>No route matches {:action=>"show", :controller=>"cases", :area=>#<Case id: 2, </code></pre> <p>It seems that rails does not get the :area from the parameters automatically. I could fix this forcing the area creating a link with</p> <pre><code>link_to("Show this case", case_path(params[:area], @item)) </code></pre> <p>to obtain the link to</p> <pre><code>example.com/area1/cases/3 </code></pre> <p>but I really don't like it. Am I doing something wrong? Why rails bring over the controller and the action but forget about the area?</p>
