Cache context based on record

We allow access to certain fields on the user (email, etc.) only if context[:current_user] == record but this can't currently be used with caching in any reasonable manner.

For now I'm just caching a copy for each user who sees it, but that's absurd and definitely not what we need. Is there a better solution, or would it be possible to get the record inside Resource.attribute_caching_context(context)?

首先阅读 Resource.attribute_caching_context(context)，并追踪 context[:current_user] 如何与缓存结合使用。将其与 issue 中描述的当前按用户复制的方法进行比较。完成的要求是达成一致的记录感知型缓存行为，但 issue 未指定任何文件、测试或具体的验收标准。
