How to access URL helper from rails module

Question

I have a module with a function. It resides in /lib/contact.rb:

module Contact   class << self     def run(current_user)       ...     end   end end 

I want to access the URL helpers like 'users_path' inside the module. How do I do that?

Answer 1

In your module, just perform a :

 include Rails.application.routes.url_helpers 

Answer 2

Here is how I do it in any context without include

routes = Rails.application.routes.url_helpers url = 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   end end 

and this does not work

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

One more example with Capybara tests

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

and now the right one

include Rails.application.routes.url_helpers feature 'bla-bla' do   path = some_path #this is ok end
