读取对象持久存在，但尚未用学说刷新 [英] read objects persisted but not yet flushed with doctrine

问题描述

我是 symfony2 和学说的新手.这是我看到的问题.我不能使用:

I'm new to symfony2 and doctrine. here is the problem as I see it. i cannot use :

$repository = $this->getDoctrine()->getRepository('entity');
$my_object = $repository->findOneBy($index);

在一个持久化的对象上，但尚未刷新！！我认为 getRepository 从数据库读取，因此它不会找到未刷新的对象.

on an object that is persisted, BUT NOT FLUSHED YET !! i think getRepository read from DB, so it will not find a not-flushed object.

我的问题:如何在我刷新整个批次之前读取那些持久化的对象(我认为它们在教义会话"中的某个地方)以重新使用它们?

my question: how to read those objects that are persisted (i think they are somewhere in a "doctrine session") to re-use them before i do flush my entire batch ?

每个配置文件都有 256 个物理羽状物.

every profile has 256 physical plumes.

每个配置文件都有 1 个分配给它的 plumeOptions 记录.

every profile has 1 plumeOptions record assigned to it.

在plumeOptions 中，我有一个cartridgeplume，它是PhysicalPlume 的FK.

In plumeOptions, I have a cartridgeplume which is a FK for PhysicalPlume.

每个羽流都由 ID(自动生成)和 INDEX(用户生成)标识.

every plume is identified by ID (auto-generated) and an INDEX (user-generated).

规则:我说配置文件 1 与 physical_plume_index 编号 3(=index)相连.

rule: I say profile 1 has physical_plume_index number 3 (=index) connected to it.

现在，我想将一个配置文件及其所有相关数据复制到另一个配置文件中.

now, I want to copy a profile with all its related data to another profile.

新配置文件已创建.新的 256 个羽流是从旧的配置文件中创建和复制的.

new profile is created. New 256 plumes are created and copied from older profile.

我想将新配置文件链接到新的羽流指数 3.

推荐答案

我想你可能想看看这个功能:

I think you might want to have a look at this function:

$entityManager->getUnitOfWork()->getScheduledEntityInsertions()

返回一个持久化的实体对象列表.

Gives you back a list of entity objects which are persisting yet.

嗯，我并没有很好地阅读您的问题，通过上面的内容，您将检索完整列表(作为数组)，但您无法像使用 getRepository 那样查询它.我会试着为你找到一些东西..

Hmm, I didn't really read your question well, with the above you will retrieve a full list (as an array) but you cannot query it like with getRepository. I will try found something for u..
