条件页面缓存[解决方案：条件片段缓存] [英] Conditional Page Caching [Solution: Conditional Fragment Caching]

问题描述

假设我的控制器 home_controller.rb 的操作为 index 。

Suppose that I have controller home_controller.rb with action index.

我想缓存索引页，所以我在做：

I want to cache index page so I'm doing:

caches_page :index

，但希望它仅对未登录的用户进行缓存。如果我将条件作为：

but want it to cache only for users that are not signed in. If I'll make conditional like:

caches_page :index, :if => :user_not_signed_in?

页面将被缓存，而第一个未登录的用户来了。现在，每个登录用户也可以看到未登录的内容。有没有办法在不更改URL的情况下分隔此操作？

Page will be cached while first not logged in user comes. Now every logged in user also see not-logged in content. Is there a way to separate this action without changing url?

推荐答案

cache_if 和 cache_unless 似乎是现在执行此操作的正确方法：

cache_if and cache_unless seems to be the correct way to do this now:

cache_if(condition, name = {}, options = nil, &block)
cache_unless(condition, name = {}, options = nil, &block)

您的代码：

<％cache_unless @ user.changed？，[@用户，表单]做％>
