Calling helper method in services

Question

Can't seem to call this helper method from a service I created. They look like this:

# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  helper_method :activate_session_with_id

 def activate_session_with_id(domain, token)
   #do some stuff
 end
end

My service looks like:

# app/services/fulfillment_order.rb
class FulfillmentOrder
  def create_order_user_fulfilled
    shop = Shop.find_by(shopify_domain: @domain)
    shop_token = shop.shopify_token
    ApplicationController.helpers.activate_shopify_session_with_id(@domain, shop_token)
  end
end

When I do that, I get this error

NoMethodError  (undefined method activate_shopify_session_with_id

I also tried to call the helper method straight up, like this:

activate_shopify_session_with_id(@domain, shop_token)

No luck with either way. Where did I go astray?

Answer 1

Need of calling controller's method outside of controller means you have defined this method in the wrong place.

You could move the method to some helper module and use in both places (by including it).

That's said, to make your attempt working:

ApplicationController.new.activate_session_with_id(domain, token)
