Hi all,  
Yesterday I released a new Rails plugin: cached\_models.  
It allows to transparently use the internal Rails cache mechanism in  
your models, avoiding to write code for expiring policies.

Example

class Project \< ActiveRecord::Base  
has\_many :developers, :cached =\> true  
end

class Developer \< ActiveRecord::Base  
belongs\_to :project, :cached =\> true  
end

# Automatic cache, all the following calls will be served by the cache.

project.developers

developer = project.developers.first  
developer.update\_attributes :first\_name =\> ‘Luca’

# Database update and cache expiring for project.

project2.developers \<\< developer

# Database update and cache expiring for project and project2

This is a 0.0.1 release, it actually support only the has\_many relation.  
BTW I’d really like to receive a lot of feedbacks and comments.
