Doctrine2 - 有预选钩吗？ [英] Doctrine2 - is there a pre-selection hook?

问题描述

我正在使用Symfony2 / Doctrine2开发一个ws，我试图钩住Doctrine2生命周期，并在任何SELECT操作之前触发一个函数，但没有任何运气。基本上，我想在请求中找到某些参数时动态地操作选择查询添加limit / offset，但是似乎 Doctrine2 hooks 仅涉及插入，删除和更新操作。我错过了什么吗？

谢谢。

解决方案

使用教义过滤器

Doctrine 2.2具有一个过滤器系统，允许开发人员将SQL添加到查询的条件子句，无论生成SQL的位置（例如，从DQL查询或通过加载关联实体）。

I'm developing a ws with Symfony2 / Doctrine2, and I'm trying to hook into Doctrine2 lifecycle and trigger a function before any SELECT action - but without any luck. Basically, i'd like to dynamically manipulate the selection queries adding limit/offset when certain parameters are found in the request, but it seems that Doctrine2 hooks concern only insert, delete and update actions. Am i missing something?

Thanks.

解决方案

U have to use Doctrine Filter

Doctrine 2.2 features a filter system that allows the developer to add SQL to the conditional clauses of queries, regardless the place where the SQL is generated (e.g. from a DQL query, or by loading associated entities).
