I figured it out. It was directly related to the form_for syntax. I guess that when rails generates the alternative explicit index route. In this case "admin_news_index" vs "admin_news" a more explicit syntax is needed.
Instead of this: <% form_for [:admin, @news] do |f| %> I found this solved my problem: <% form_for @news, :url => admin_news_index_path do |f| %> --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
