safe_callbacks

Tired of writing the following (or forgetting) ?

class User
  before_validation :denormalize_a_bool

private

  def denormalize_a_bool
    self.a_bool = something_is_true?
    true
  end
end

Without that last 'true', the callback chain will be halted.

Usage

gem 'safe_callbacks'

and then:

class MyClass
  include MongoMapper::Document
  include SafeCallbacks
end

or:

SafeCallbacks.extend_mongo_mapper!

for all models
