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?

Module ActionView::Helpers::UrlHelper. Provides a set of methods for making links and getting URLs that depend on the routing subsystem (see ActionDispatch::Routing). This allows you to use the same format for links in views and controllers.
Decoding the http request TIP: If you ever want to list all the routes of your application you can use rails routes on your terminal and if you want to list routes of a specific resource, you can use rails routes | grep hotel . This will list all the routes of Hotel.
In your module, just perform a :
include Rails.application.routes.url_helpers 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 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
