link_to redirect to a wrong controller

I have a layout for my admin area called 'layout_admin' . In 'layout_admin', I have :

<li><%= link_to 'Contenu', :action=>'index', :controller=>'contents' %></li>
<li><%= link_to 'Petitions', :controller => 'petitions', :action => 'index' %></li>

The first link for Contenu works fine, but the second one (for petitions) drives me to a strange error :

Routing Error No route matches {:controller=>"admin/edito"}

In the address bar I have : localhost:3000/admin/petitions

In routes.rb I have :

namespace :admin do resources :petitions 
end

I must also precise that "edito" is another controller outside the admin area which has one action "index". In routes.rb I have get "edito/index" concerning edito_controller.

Does somebody have an idea of the source of the problem ? Thansk.

See the route names in the left column of your rake routes? Use that info to build calls to different path helpers:

<li><%= link_to 'Contenu', admin_contents_path %></li>
<li><%= link_to 'Petitions', admin_petitions_path %></li>

In general, that's how you should be building URLs in your Rails 3+ app.

Read through Rails Routing from the Outside In for more information (particularly 2.3: Paths and URLs).

Update:

You should look into using these _path-style helpers on the view that's being pulled up when you visit /admin/petitions.

I bet you have a link on the page similar to this:

<%= link_to "Link Text", :controller => "edito", :action => "index" %>

It's trying to find edito in the admin namespace because that's where you are within the app when you visit /admin/petitions.

To fix, you need to update it to read like this:

<%= link_to "Link Text", edito_index_path %>

Wash, rinse, and repeat for all links, forms, and url_for references in your app.
