Where to override current_user helper method of devise gem

Question

How can i override current_user of devise gem. Actually I need to add web services for mobile-app.

Currently devise is managing session and 'current_user' for web-application.

Now Mobile app will send user_id to the server. I need to override current user like this

def current_user   if params[:user_id].blank?     current_user   else     User.find(params[:user_id])   end    end 

Should I need to modify devise gem as plugin ? or something else ?
Kindly explain in detail as I am new in rails.

Kind regards,

According to the module Devise::Controllers::Helpers, current_user (together with all other devise helpers) is added to ApplicationController, which means that you can override it in this way:

# in application_controller.rb  def devise_current_user   @devise_current_user ||= warden.authenticate(scope: :user) end  def current_user   if params[:user_id].blank?     devise_current_user   else     User.find(params[:user_id])   end    end
