Makes Activerecord Observers lazy, do not load model on startup and only listen once a model got loaded.
Simple and powerful implementation of the observer pattern.
This is an alternative implementation of the observer pattern. As you may know, Ruby (and Rails/ActiveRecord) already have an implementation of it. This implementation is a variation of the pattern, so it is not supposed to supersede the existing implementations, but "complete" them for the specific use-cases addressed.
Adds support for ActiveModel Observers
This is a DataMapper plugin that provides observers for DataMapper resource classes. It's compatible with DataMapper 0.9.1.
Every class or object can be transformed to observer and dynamically react to data changes across several models. Observable module is using build in Active Record hooks or database triggers which can be turned on in multiple App environment.
This Gem provides two interfaces, one to make items observable, and another to easily create classes to observe them.
Quick and easily share the controller information with observers, including session information.
A library that gives observers some context.
