Question

我想使用memcached存储一个简单的活动记录对象。我知道我需要先将对象转换为JSON，然后再将其保存到memcached我的问题是如何将其拉出来，反序列化并将其用作activerecord关系。我是否必须使用JSON自定义解析器，或者我是否忽略了一些简单的解决方案？

活动记录对象如下所示：

+------+-----+-----------+---------------------------------+---------------------+-------+
| id   | ppl | exclusive | name                            | price               | spots |
+------+-----+-----------+---------------------------------+---------------------+-------+
| 8948 | 12  | false     | 12 Bed Mixed Dorm               | 9.0000000000000000  | 12    |
| 8947 | 10  | false     | 10 Bed Mixed Dorm               | 9.5000000000000000  | 10    |
| 8946 | 6   | false     | 6 Bed Mixed Dorm                | 10.0000000000000000 | 6     |
| 8945 | 4   | false     | Basic 4 Bed Mixed Dorm          | 10.0000000000000000 | 4     |
| 8944 | 2   | true      | Twin Private Shared Bathroom    | 12.0000000000000000 | 1     |
| 8943 | 1   | true      | Standard Single Private Ensuite | 15.0000000000000000 | 1     |
+------+-----+-----------+---------------------------------+---------------------+-------+

您不应该担心序列化 - 几乎在所有情况下，都可以为您处理：

#Gemfile
gem install dalli

#config/environments/production.rb
config.cache_store = :dalli_store, '127.0.0.1' #use memcached

#Get id 1245 from model_names
Rails.cache.fetch("ModelName#1245") do
  ModelName.find(1245)
end

rails对象memcached然后再出来
