Unpacked gem authlogic-2.1.3 in vendor/gems has no specification file. Run 'rake gems:refresh_specs' to fix this.

You can solve this issue by following way

> cd vendor/gems/authlogic-2.1.3
> gem specification authlogic > .specification

Get Session Data Available in Models - Ruby on Rails

Sometimes we really need session variables inside model. But as the rails framework defines (MVC) pattern. 

This pattern separates the context of the Web Application (Controller,View) from the Model. Model contains business logic of the web application. The Controller handles the interactions between the View and the Model. 

So you can not access sessions directly in your model. You can crack it by following way.

Create one module 

module Utility
  def current_user
    Thread.current[:user]
  end
 
  def self.current_user=(user)
    Thread.current[:user] = user
  end
end

Add following in application controller

class ApplicationController < ActionController::Base
  include Utility
  before_filter :set_user_session
 
  protected
  def set_user_session
    Utility.current_user = session[:user]
  end
end

And now get it in your model

class Account < ActiveRecord::Base
  include Utility
 

  def before_create
    unless allowed?(current_user)

      return false 

    end
  end
end
