Simple
If you want to use a helper_method my_helper_method inside a model, you can write
ApplicationController.helpers.my_helper_method
When using multiple helpers
delegate :helpers, to: ApplicationController
helpers.my_helper_method
helpers.my_other_helper-method
More flexible
If you need a bit more flexibility, for example if you also need to override some methods, you can do this:
class HelperProxy < ActionView::Base
include ApplicationController.master_helper_module
def current_user
#let helpers act like we're a guest
nil
end
def self.instance
@instance ||= new
end
end
and then use with
HelperProxy.instance.my_helper_method
Bare metal
If you have strong nerves, you can also try to include the ApplicationController.master_helper_module directly into your model.
