doctrine：设置与id而不是对象实例的关联 [英] doctrine: setting association with id instead of object instance

问题描述

可以设置两个对象之间的关联，例如文章和注释，如下所示：

is it possible to set associations between two objects, for example article and comment like this:

comment.setArticle(10) // 10 is the id of article

自动生成setArtcicle方法作为参数对象文章当然，但也许有一些技巧这样做？

autogenerated setArtcicle methods takes as argument object Article of course but maybe there are some tricks to do this?

它从性能角度来看，对我来说非常重要 - 我想避免在要设置关联时总是使用SQL调用。在我的情况下会有很多这样的不必要的查询。

It is very important to me from performance point of view - i would like to avoid making SQL calls always when I want to set an association. In my case there will be plenty of such unnecessary queries.

推荐答案

你可以使用：

$comment->setArticle($em->getReference('Article', 10));
