CASE WHEN Menu based off of Routes.rb and Request.path

I have a case when clause where based on the URL that you're at, it will bring in different menu options. However, depending on some of the menus that you could be at, it doesn't recognize that you have some variables assigned. The system errors:

ActionController::RoutingError in Pages#users_page

Showing /home/initiald/RubymineProjects/SOWOnline/app/views/layouts/_navigation.html.erb where line #27 raised:

No route matches {:controller=>"results", :action=>"show"}

Here is the code that I have so far

<% case request.path %>
  <% #ROOT AND SETTINGS %>
  <% when '/', settings_path, '/guest' %>
  <% #SURVEY 开发者_Python百科AND RESULTS %>
  <% when '/sow_survey', '/surveys', '/results', result_path, results_path, available_surveys_path, take_survey_path, view_my_survey_path, edit_my_survey_path %>
    <% if permitted_to? [:admin, :partner, :employee], :users  %>
      <%= link_to 'new survey', available_surveys_path %>
      <%= link_to 'edit survey', results_path %>
    <% end %>
  <% #USERS %>
  <% when '/register' , '/users', '/sow_users', edit_user_path %>
      <% if permitted_to? [:admin, :partner, :employee], :users  %>
          <%= link_to 'new user', register_path %>
          <%= link_to 'list users', list_users_path %>
      <% end %>
  <% else %>
<% end %>

There is no any result_path without attributes, but there is result_path(result_id) path, which is:

{:controller=>"results", :action=>"show", :id => your_paticular_id}

and looks like

/results/:id

UPD

Just use regular expression here:

<% when '/sow_survey', '/surveys', '/results', /\/results\/\d*/, results_path, available_surveys_path, take_survey_path, view_my_survey_path, edit_my_survey_path %>

And yes - your code is messy.
