Mass assignment security provides an interface for protecting attributes from end-user assignment. For more complex permissions, mass assignment security may be handled outside the model by extending a non-ActiveRecord class, such as a controller, with this behavior.

For example, a logged in user may need to assign additional attributes depending on their role:

class AccountsController < ApplicationController

  include ActiveModel::MassAssignmentSecurity

  attr_accessible :first_name, :last_name

  def self.admin_accessible_attributes
    accessible_attributes + [ :plan_id ]
  end

  def update
    ...
    @account.update_attributes(account_params)
    ...
  end

  protected

  def account_params
    sanitize_for_mass_assignment(params[:account])
  end

  def mass_assignment_authorizer
    admin ? admin_accessible_attributes : super
  end

end
