Tableless model in rails 3.1

Question

Looks like this method doesn\'t work anymore in rails 3.1. So, does someone have a working solution?

Actually, I\'ve found this gist. It solves problems with colum

Answer 1

The simplest tableless model in Rails 3.1 is:

class Session
  include ActiveModel::Validations
  include ActiveModel::Conversion
  extend ActiveModel::Naming

  attr_accessor :email, :password
  validates :email, :presence => true
  validates :password, :presence => true

  def initialize(attributes = {})
    if attributes
      attributes.each do |name, value|
        send("#{name}=", value)
      end
    end
  end

  def persisted?
    false
  end
end

The ActiveModel::Validations is optional (only if validations are used). Also the constructor is not required (but highly desireable).
