Question

我想知道是否可以删除模板缓存中生成的缓存内容。我想从我的视图中删除它。我的模板{% 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，当进行某些操作时？
我想使用per-vie cache。我做了所描述的所有内容，但是当我打电话时：@cache_page(3600, cache="cache_name")我收到错误：

异常类型：ValueError异常价值：需要超过1个值解压

（以下是追溯）

我想要实现的是缓存我的所有模板块或视图，并且可以在执行某些操作时删除与其关联的所有缓存。包括分页

Answer 1

您使用的是什么版本的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”。
