model-cache

ModelCache to use on an ActiveRecord class to cache method calls. Example:

Class X < ActiveRecord::Base
def heavy_calculation(a, b)
"result #{self.x} #{a} #{b}"
end

include ModelCacheHelper
cache_method :heavy_calculation
endThe created method X.heavy_calculation(id, arg1, arg2) will then check if the result is cached, otherwise it will do X.find(1).heavy_calculation(arg1, arg2) and cache the result. Calling heavy_calculation on an instance of X will also cache the result.

The instance method expire_cache, will expire the cache for that object. It can be used with an optional argument, expire_cache(method), to only expire the cache for a certain method.

Non-string result will be serialized with YAML and automatically deserialized when loaded.

The extra argument kan be used to define extra parameters to the find-request.

cache_method :heavy_calculation, :include => "content_items"
