如何强制学说从数据库重新加载数据? [英] How do I force doctrine to reload the data from the database?

问题描述

我在 symfony2.1 安装中使用了学说/mongodb 1.0.0-BETA1.

I'm using doctrine/mongodb 1.0.0-BETA1 in a symfony2.1 install.

所以我试图强制我的存储库从我的数据库中调用数据，而不是使用它缓存的对象.

So i'm trying to force my repository to call data from my database instead of using the object it has cached.

$audit = $dm->getRepository("WGenSimschoolsBundle:Audit")->findOneById("xxxx");

.... do something somewhere to change the object ....

此时如果我打电话

$audit = $dm->getRepository("WGenSimschoolsBundle:Audit")->findOneById("xxxx");

审计数据没有改变.它仍然具有它最初获取的对象.如果我尝试

The audit data hasn't changed. It still has the object it originally fetched. If I try to

$dm->refresh($audit) 

我得到了同样的东西.无论如何，我是否可以返回数据库获取值?

I get the same thing. Is there anyway for me to go back to the database for the value?

推荐答案

您是否已将更改刷新到 $audit 对象?

Have you flushed your changes to the $audit object?

$audit = $dm->getRepository("WGenSimschoolsBundle:Audit")->findOneById("xxxx");
//do something somewhere to change the object
$dm->flush();

<小时>

每次执行 findBy(...) 或 findOneBy(...) 时，它实际上都会从数据库中获取一个新文档.(您应该在 Symfony 分析器中看到查询)

---

Every time you do a findBy(...) or findOneBy(...) it actually fetches a new document from the DB. (you should see the query in the Symfony profiler)

用 find() 代替，它将从他的内部代理缓存中获取文档.文档将保留在代理缓存中，直到您调用 $dm->clear() 方法.

With a find() instead, it will fetch the document from his internal proxy cache. The Documents stay in the proxy cache until you call the $dm->clear() method.
