Get model for current controller

Question

I am building a controller concern, and inside it I need a reference to the current controller's related model. So, if I have something like:

class UsersController < ApplicationController
  include Concern
end

module Concern
  extend ActiveSupport::Concern

  def bla
    self.model # ??
  end
end

I would like in bla to get a reference of the current model, so that when I include Concern in UserController, I get a User reference.

Is this possible in Rails?

Answer 1

You can do this, but only if you have followed Convention over Configuration for naming the controller and model

controller_name.classify.constantize
