仅将缓存资金用于单个模型?

问题描述

我想使用缓存资金，但是我不想开始自动缓存所有内容(我正在使用大型生产应用程序，数TB的数据等).如何仅将其用于指定的模型?现在我有:

I want to use cache-money but I don't want to start automatically caching everything (I'm working with a large production app, terabytes of data etc). How do I use it for only the models that I specify? Right now I've got:

# initializers/cache_money.rb
require 'cache_money'

config = (cfg = YAML.load(IO.read(File.join(RAILS_ROOT, "config", "memcached.yml"))))[RAILS_ENV] || cfg["defaults"]
$memcache = MemCache.new(config)
$memcache.servers = config['servers']

$local = Cash::Local.new($memcache)
$lock = Cash::Lock.new($memcache)
$cache = Cash::Transactional.new($local, $lock)

，然后在该模型中，我想用cache-money进行缓存:

and then in the model I want to cache with cache-money:

# my_model.rb
class MyModel < ActiveRecord::Base
  is_cached :repository => $cache
  # ...
end

但这是行不通的；调用is_cached会出现以下错误:NoMethodError:Config:Module的未定义方法"create"

But this doesn't work; the call to is_cached gives the following error: NoMethodError: undefined method `create' for Config:Module

有什么想法吗?失败了，在任何地方我都可以寻求有关缓存资金的帮助吗?我找不到邮件列表或其他任何内容.

Any ideas? Failing that, is there anywhere I can go for help with cache-money? I couldn't find a mailing list or anything.
