缓存资金:仅用于生产?

幸亏 Obie Fernandez 对于一个伟大的离线提示:stubout cache money的#index方法什么也不做。这为模型中的#index语句提供了一个位置,并停止了上述错误。

if RAILS_ENV != 'development'
  require 'cache_money'

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

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

  class ActiveRecord::Base
    is_cached :repository => $cache
  end
else
  # If we're in development mode, we don't want to
  # deal with cacheing oddities, so let's overrite
  # cache-money's #index method to do nothing...
  class ActiveRecord::Base
    def self.index(*args)
    end
  end
end

通过在测试中关闭缓存金钱,您无法知道它是否会干扰您的代码。

我改为:

require 'cache_money'
require 'memcache'

if RAILS_ENV == 'test'
  $memcache = Cash::Mock.new
else
  config = YAML.load(IO.read(File.join(RAILS_ROOT, "config", "memcached.yml")))[RAILS_ENV]
  $memcache = MemCache.new(config)
  $memcache.servers = config['servers']
end

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

class ActiveRecord::Base
  is_cached :repository => $cache
end

unless 'development' == RAILS_ENV
  require 'cache_money'
  ....
