问题描述
我使用的是 Magento Enterprise 1.10.1.1,需要在我们的产品页面上获取一些动态内容.我在块中插入当前时间以快速查看它是否正常工作,但似乎无法通过整页缓存.

推荐答案
cache.xml 中的
必须与布局中的块全名匹配,而不是别名,例如
The <name>
in the cache.xml must match your blocks full name in the layout, not the alias, e.g. <name>product.info.example</name>
此外,_getIdentifier()
未在 Enterprise_PageCache_Model_Container_Abstract
上实现,只需将其从 _getCacheId()
返回的字符串中删除即可.如果您需要添加一些变体,请实现 _getIdentifier()
以返回会话 ID 或您需要的任何内容.
Also, _getIdentifier()
isn't implemented on Enterprise_PageCache_Model_Container_Abstract
, just remove it from the string returned by your _getCacheId()
.
If you need to add some variants, implement _getIdentifier()
to return a session id or whatever you need.
