Rails routing url name helpers

Question

What basic settings are required to make sure routing url name helpers work?

For instance in my route I have the following:

Blog::Application.routes.draw do
  resources :news, :as => :news_items, :controller => :news_items, :only => [:show, :index]

  scope :module => "refinery" do
    scope(:path => 'refinery', :as => 'admin', :module => 'Admin') do
      resources :news, :except => :show, :as => :news_items, :controller => :news_items
    end
  end
end

but the following doesn't seem to work:

new_refinery_news_url

I keep on getting the error

undefined local variable or method `new_refinery_news_url'

So I'm pretty sure something is missing in the way I have configured my application, who's main routing is in the RefineryCMS gem which was added in the Gemfile.

Any thoughts?

Answer 1

Had to use main_app.new_refinery_news_url instead.

Answer 2

The helper name will be new_admin_news_item_url.

It's simple to find all routes and their helper methods. Just run rake routes and you will see:

          news_items GET    /news(.:format)                   {:action=>"index", :controller=>"news_items"}
           news_item GET    /news/:id(.:format)               {:action=>"show", :controller=>"news_items"}
    admin_news_items GET    /refinery/news(.:format)          {:action=>"index", :controller=>"refinery/Admin/news_items"}
                     POST   /refinery/news(.:format)          {:action=>"create", :controller=>"refinery/Admin/news_items"}
 new_admin_news_item GET    /refinery/news/new(.:format)      {:action=>"new", :controller=>"refinery/Admin/news_items"}
edit_admin_news_item GET    /refinery/news/:id/edit(.:format) {:action=>"edit", :controller=>"refinery/Admin/news_items"}
     admin_news_item PUT    /refinery/news/:id(.:format)      {:action=>"update", :controller=>"refinery/Admin/news_items"}
                     DELETE /refinery/news/:id(.:format)      {:action=>"destroy", :controller=>"refinery/Admin/news_items"}

Answer 3

With mountable engines you always need to specify "main_app." (or for Refinery routes "refinery.") prefix because engines are isolated from the application.

Answer 4

A solution, if you're using routes outside of refinery, is to prefix the named_path with the Rails object that contains the methods for named routes

Rails.application.routes.url_helpers.new_admin_news_item_path
