How to use url helpers in lib modules, and set host for multiple environments

Question

In a Rails 3.2 app I need to access url_helpers in a lib file. I\'m using

Rails.application.routes.url_helpers.model_url(model)

<

Answer 1

Use this string in any module controller to get application URL-helpers works in any view or controller.

include Rails.application.routes.url_helpers

Please note, some internal module url-helpers should be namespaced.

Example: root application

routes.rb

Rails.application.routes.draw do
get 'action' =>  "contr#action", :as => 'welcome'
mount Eb::Core::Engine => "/" , :as => 'eb'
end

Url helpers in module Eb:

users_path

Add include Rails.application.routes.url_helpers in controller contr

So after that helper should be

eb.users_path

So inside Eb module you can use welcome_path same as in root application!
