h1. ModelCache

ModelCache is a simple caching plugin for Rails, using memcached. It provides caching abilities for your models, allowing to:
* cache blocks of code in your model instance methods, based on a generic key (ActiveRecord cache_key is added behind the scenes)
* cache your instance methods, optionally with a time-to-live setting
* cache some generic code (e.g. in your class methods)

h1. Example

p. environment.rb:

bc. require 'memcache'
CACHE = MemCache.new('127.0.0.1')

p. Your model:

bc.. class Stuff < ActiveRecord::Base

	def expensive_method
		...
	end
	
	def another_expensive_method
		...
	end
	
	cache_method :expensive_method, :another_expensive_method
	
	def third_expensive_method
		...
	end
	
	cache_method_for_time :third_expensive_method, 1.hour
	
	def partially_expensive_method
		...
		cache :calculation do
			...
		end
	end
	
	def self.some_class_method
		ModelCache.cache(:this_would_be_persistent, 5.minutes) do
			...
		end
	end

end

p. Cached!
