Symfony 生成器形式、学说和 M:N 关系-php问题

Symfony Generator Forms, Doctrine, and M:N Relationships(Symfony 生成器形式、学说和 M:N 关系)

本文介绍了Symfony 生成器形式、学说和 M:N 关系的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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

config/doctrine/schema.yml (注意:不是整个schema.yml，只是这里讨论的表)

apps/backend/modules/candidate/config/generator.yml

generator:
  class: sfDoctrineGenerator
  param:
    model_class:           Candidate
    theme:                 admin

      fields:

        last_name:  { label: Last Name }
        created_at: { label: Created On }
        candidate_positions:  {label: Positions}
      list:    
        sort:  [last_name, asc]
      filter:  ~
      form:    
        display:
          "User": [first_name, last_name]
          "Applying For": [candidate_positions]
        fields :
          hide:  [created_at]
      edit:    ~
      new:     ~

lib/form/doctrine/candidateForm.class.php

class candidateForm extends BasecandidateForm
{
  public function configure()
  {
    unset( $this['created_at'] );

    $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.
