如何在Doctrine2 CTI继承中更改和实体类型 [英] How to change and entity type in Doctrine2 CTI Inheritance

问题描述

如何（如果可能的话）你用Doctrine2改变实体类型，使用它的Class Table Inheritance？

How (if possible at all) do you change the entity type with Doctrine2, using it's Class Table Inheritance?

假设我有一个 Person 父类类型和两个继承类型 Employe 和 Client 。我的系统允许创建一个Person并指定它的类型 - 这是相当容易实现 - 但我也希望能够将人从Employe改为客户端，同时保持 Person -level信息（它的id和其他相关记录）。

Let's say I have a Person parent class type and two inherited types Employe and Client. My system allows to create a Person and specify it's type - that's fairly easy to implement - but I'd also like to be able to change the person from an Employe to a Client, while maintaining the Person-level information (it's id and other associated records).

有一个简单的方法来做这个与Doctrine2？

Is there a simple way to do this with Doctrine2?

推荐答案

我昨天也在寻找这个行为。

I was looking for this behaviour yesterday also.

最后，在与freenode上的#doctrine的人交谈后，我被告知这是不可能的。

In the end, after speaking with people in #doctrine on freenode, I was told that it is not possible.

如果您想这样做，则必须执行以下操作：

If you want to do this, then you have to go through this:

1. 抓取人员实体。


2. 更新歧视器列，使其不再是person，并更改为employee。


3. 在<

删除继承

同样，如果你想删除继承，你必须... ..

Removing Inheritance

Likewise if you want to remove inheritance, you have to..

1. 获取Person Entity。 >
   
2. 更新歧视器列，使其不再是员工，并更改为人员。


3. 删除 Employee 表。 （是的，你必须删除它，只是更改歧视器列是不够的）。

1. Grab the Person Entity.
2. Update the discrimnator column so that it is no longer an 'employee' and change it to a 'person'.
3. Delete the corresponding row in your Employee table. (Yes you have to delete it, just change the discrimator coumn is not sufficient).

这可能迟了7个月，但至少是正在寻找支持这样的功能的正确答案。

This might be 7 months late, but it is at least the correct answer for anything else looking to suport such a feature.
