我有一个基本的 M:N 设置，其中包含三个表:候选、位置和候选位置.
I have a basic M:N setup with three tables: candidate, position, and candidate_position.
这是来自 MySQL Workbench 的 ERD 的屏幕截图
Here's a screenshot of the ERD from MySQL Workbench
现在，让我们继续讨论表单.在 symfony 生成器的默认世界中，这三个表都有一个单独的 CRUD 接口.但是，我不想为 candidate_position 提供 CRUD 接口.
Now, moving on from that let's talk about forms. In the default world of symfony generator, you'd have a separate CRUD interface for all three of these tables. However, I don't want to have a CRUD interface for candidate_position.
我想要的是，候选界面的创建和编辑操作包含一个多选字段(选择列表、复选框数组等)，它将创建候选位置记录作为候选操作的一部分.
What I want, is for the create and edit actions of the Candidate interface to contain a multi-choice field (select list, checkbox array, whatever) that would create the CandidatePosition records as part of the Candidate actions.
进入代码

$this->widgetSchema['candidate_positions'] = new sfWidgetFormDoctrineChoice(
array( 'multiple' => true, 'model' => 'Position', 'renderer_class' => 'sfWidgetFormSelectCheckbox' )
);
$this->validatorSchema['candidate_positions'] = new sfValidatorDoctrineChoice(
array( 'multiple' => true, 'model' => 'Position', 'min' => 1 )
);
}
}
这一切都有效，除了实际保存数据时.这就是我卡住的地方.
This all works, except when it comes to actually saving the data. This is the point where I get stuck.
我显然需要做一些事情来创建/编辑/删除 CandidatePosition 记录，但我不确定从哪里开始工作.在 candidateActions 中?覆盖 Basecandidate::save()?
I clearly need to do something to create/edit/delete the CandidatePosition records, but I'm not sure where to start working. In candidateActions? Override Basecandidate::save()?
如果您可能需要查看任何其他数据，请告诉我.
Let me know if there's any other data you might need to see.
大约 10 个月前，我在连接表中的 M:N 关系和元数据方面遇到了类似的问题.
About 10 month ago I had similar trouble with M:N relationships and meta-data in the join table.
我发现 melikedev 的那些博客条目非常有用！这与您的用例并不完全相同，但它可能会给您一些提示:
I found those blog entries of melikedev very useful! This is not exactly the same as your use case, but it might give you some hints:
