This module adds the
attributes method to controllers which makes it possible
to do mass assignment, while making sure that only trusted attributes are
updated. In effect it moves mass assignment protection to the controller.
Add the gem to your Gemfile:
Include it in your application controller:
class ApplicationController < ActionController::Base include TrustedAttributes end
Whenever you would normally assign a hash from params, use
instead. For example:
def create @realm = Realm.new(attributes) if @realm.save redirect_to @realm else render :new end end
To mark attributes as trusted, you can use the
trust class method:
class RealmsController < ApplicationController trust :name, :max_data, :max_time def create @realm = Realm.new(attributes) ... end end
You can also use the instance method
trust, for example if different users
have access to different attributes:
class RealmsController < ApplicationController trust :name, :max_data, :max_time def create trust :global if current_user.admin? @realm = Realm.new(attributes) ... end end
When not running in production mode, an error will be raised when non trusted attributes are sent, in production mode, the non trusted attributes are silently ignored.
