Question

I am using Devise in Rails 3, and have a User model in rails that is starting to get kinda crowded.. so I would like to put all of the login meethods inside of a module and include them from my model. I’m trying something like:

app/model/user.rb

class User < ActiveRecord::Base
  include UserImageable
  extend Loginable

  has_one  :profile, :dependent => :destroy
  has_many :items, :dependent => :destroy
  has_many :products, :through => :items

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :first_name, :last_name, :phone_number, :location, :photo, :profile_attributes, :access_token
  delegate :first_name, :last_name,  :phone_number, :phone_number=, :location, :location=, :photo,  :to  => :profile

  accepts_nested_attributes_for :profile
end

and

lib/autoloads/loginable.rb

module Loginable
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :omniauthable

  def password_require?
    new_record?
  end
end

but the server doesn’t seem to like that, as it loads with a NoMeethodError

loginable.rb:4:in `<module:Loginable>': undefined method `devise' for Loginable:Module (NoMethodError)

Is there a way to do what I’m shooting for, or not really?

Thanks

This is not the answer you are looking for but, here is my 2 cents: You shouldn’t put all that stuff in the User model. devise models have a clear responsibility: signing.

But if you really want to put everything hooked in User.rb, you can split the model in extensions (partially enabling DCI):

Add that to your lib/models/{modelname}/devise_ext.rb

module Models
    module User
        module DeviseExt
            extend ActiveSupport::Concern

            included do
                        devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable, :omniauthable

            end

            module ClassMethods

            end

            module InstanceMethods      

                def password_require?
                                new_record?
                            end
            end #InstanceMethods

        end
    end
end

Then, you just add it into your model:

include Models::User::DeviseExt

In the app we have in my company we actually have no code at all in models, we put everything in extensions.
