治具-圆形参考 [英] Doctrine fixtures - circular references

问题描述

有什么方法可以加载具有循环参考的灯具？例如，我有以下固定装置：

Is there any way to load fixtures that have circular referencing? As an example I have the following fixture:

BusinessEntityTeam:
  Nicole_Team:
    name: Nicole's Team
    Manager: [Nicole]
    Business: [ACMEWidgets]

sfGuardUser
  Nicole:
    first_name:     Nicole
    last_name:      Jones
    email_address:  [e-mail]
    username:       nicole
    password:       nicole
    Groups:         [Group_abc]
    Team:           [Nicole_Team]

如您所见，Nicole_Team引用了Nicole ...，但Nicole也引用了Nicole_Team。

As you can see, Nicole_Team references Nicole... but Nicole also references Nicole_Team.

当Manager不是必需列时，可以（加载夹具，但Manager为NULL），但是现在需要不可能加载夹具。

When Manager wasn't a required column this was OK (the fixture loaded, but Manager was NULL), but now it's required it's impossible to load the fixture.

我可以看到的解决方法是将团队关系放在其自己的对象中（例如，个人资料），这样关系不再是循环的。

The only work-around I can see is to put the Team relation in its own object ('Profile' for example) so the relations are no longer circular.

是否存在其他任何关系方法？每个用户都必须在一个团队中，但是只有少数几个用户是团队经理。我很愿意接受这样的事实，即我的数据模型可能设计不良，并且还有改进的空间。

Is there any other approach? Every user has to be in a team, but only a few users are team managers. I'm quite open to the fact that my data model may be badly designed and have room for improvement.

推荐答案

：

BusinessEntityTeam:
  Nicole_Team:
    name: Nicole's Team
    Business: [ACMEWidgets]

sfGuardUser
  Nicole:
    first_name:     Nicole
    last_name:      Jones
    email_address:  [e-mail]
    username:       nicole
    password:       nicole
    Groups:         [Group_abc]
    Team:           [Nicole_Team]
    ManagerFor:     [Nicole_Team]

为了避免循环引用，必须将关系放在一个模型中。

In order to avoid circular referencing, you have to put the relations in one model.
