You may use a different model by:

  2. Overriding the user class in an initializer.
  3. Overriding the authentication helpers in your controller.

    Create a new Migration:

    rails g rename_user_id_to_new_user_id
    # db/migrate/...rename_user_id_to_new_user_id.rb

    class RenameUserIdToNewUserId < ActiveRecord::Migration def up rename_column :redactor_assets, :user_id, :admin_user_id end

    def down rename_column :redactor_assets, :admin_user_id, :user_id end end

    # config/initializers/redactor.rb
    # Overrides the user class
    module RedactorRails
      def self.devise_user
        %s(admin_user) # name of your user class
      # You may override this to support legacy schema.
      # def self.devise_user_key
      #   "#{self.devise_user.to_s}_id".to_sym
      # end
    # app/controllers/application_controller.rb
    class ApplicationController < ActionController::Base
      def redactor_authenticate_user!
        authenticate_admin_user! # devise before_filter
      def redactor_current_user
        current_admin_user # devise user helper
