Accessitude

A helper for Rails that will select only accessible parameters to be passed to a Model. This is useful for frameworks like Angularjs, which will pass all attributes in a request when only a select few should be accessible to the model.

RDoc

gem install acessitude

Now add to models that you want to have Accessitude:

require 'accessitude'
class Message < ActiveRecord::Base
  accessitude
  
  attr_accessible :title, :body, :desc
end

Now you can create a new instance in a Controller and simply pass in the entire param hash. Accessitude will only select params that have been set in the model's attr_accessible:

Message.new_from_params(params)

Also you can update an existing instance:

@message.attributes_from_params(params)

To get a list of accessible_attrs:

Message.accessitude_attrs
