一些缓存问题

Question

1. 我想知道是否可以删除在模板缓存中制作的缓存内容。我想从我的视图中删除它。我的模板中有{% cache 500 cache_name sites.number %} 是否可以删除视图中的所有“cache_name”缓存内容，例如在执行某些操作时？

2. 我想使用per-vie cache。我做了所有描述的事情，但是当我打电话时：@cache_page(3600, cache="cache_name") 我得到错误：

异常类型：ValueError异常 值：需要超过 1 个值 解压

（以下是回溯）

我想要实现的是缓存我的所有模板块或视图，并有可能在执行某些操作时删除与其相关的所有缓存。包含分页

Answer 1

您使用的是哪个版本的 Django？参数“cache”仅在开发版本中可用。如果您使用的是 Django 1.2，则只能使用“key_prefix”。
