Devise::Controllers::Helpers

[danielgrippi]

Including Devise::Controllers::Helpers in ApplicationController.rb resolves the Devise-specific before_filter :authenticate_user!, but I'm still not able to use the current_user method in my controllers. This is what happens when I try calling it:

undefined local variable or method `current_user' for #<#<Class:0x00000100f44628>:0x00000100f3d648>

It seems as if the define_helpers method isn't getting triggered in Devise. Any ideas?

Yep, looking at the define_helpers(mapping) a little further, it looks like the helper_methods only get added when action_controller gets loaded: https://github.com/plataformatec/devise/blob/master/lib/devise/controllers/helpers.rb#L56

my quick and dirty fix for now -- placing this method in application_helper:

def current_user
   @current_user ||= warden.authenticate(:scope => :user)
end

Weird. I poked around at this locally, and didn't get the problem, Devise works fine for me with just the include.

That's a weird error message to get, though, I'd expect to see the class name. Are you calling it in an instance method of a controller that inherits from ApplicationController?

Can you call define_helpers on the controller class? Then just call helper_method yourself to put it in the views.
