# In Application Controller:

# Rename your current version of 'current_user' like so:
def _current_user
  # Current User Code
end

# Change _current_user to something like this:
def current_user
  model = self.class.class_variable_get :@@model rescue nil
  param = self.class.class_variable_get :@@param rescue nil

  if model
    model.find(params[param]).customer
  else
    _current_user
  end
end


# In all subclasses of ApplicationController that require the user to be logged in:

class VideoController < ApplicationController
  @@model = Video
  @@param = :video_id

  # Rest of your code here
end
