How to access URL helper from rails module

In your module, just perform a :

 include Rails.application.routes.url_helpers

ruby-on-rails ruby url model helper

Here is how I do it in any context without include

routes = Rails.application.routes.url_helpersurl = routes.some_path

That works in any context. If you're trying to include url_helpers - make sure you are doing that in the right place e.g. this works

module Contact  class << self    include Rails.application.routes.url_helpers  endend

and this does not work

module Contact  include Rails.application.routes.url_helpers  class << self  endend

One more example with Capybara tests

feature 'bla-bla' do  include Rails.application.routes.url_helpers  path = some_path #unknown local variable some_pathend

and now the right one

include Rails.application.routes.url_helpersfeature 'bla-bla' do  path = some_path #this is okend

ruby-on-rails ruby url model helper

Delegation to url_helpers seems much better than including the whole module into your model

delegate :url_helpers, to: 'Rails.application.routes' url_helpers.users_url  => 'www.foo.com/users'
