Question

当我尝试使用Doctrine自引用关系创建ZF2表单时，我得到了Doctrine错误Method "Status::getName" is not callable

在我的实体的YAML配置下面：

Status:
  type: entity
  table: status
  fields:
    id:
      id: true
      type: integer
      generator:
        strategy: AUTO
      options:
        unsigned: true
    name:
     type: string
     length: 255
  manyToMany:
    workflow:
      targetEntity: Status
      joinTable:
        name: status_workflow
        joinColumns:
          statusId:
            referencedColumnName: id
        inverseJoinColumns:
          nextStatusId:
            referencedColumnName: id

和表格

class WorkflowForm extends Form
{
    public function init()
    {
        $this->setName('workflow');

        $this->add([
            'name' => 'workflow',
            'type' => WorkflowFieldset::class,
            'options' => [
                'use_as_base_fieldset' => true,
            ],
        ]);
    }
}

和fieldset

class WorkflowFieldset extends Fieldset ObjectManagerAwareInterface
{
    use ProvidesObjectManager;

    public function init()
    {
        $this->setName('workflow');

        $this->add([
            'name' => 'id',
            'options' => [
                'label' => 'Status name'
            ],
        ]);

        $this->add([
            'name' => 'workflow',
            'type' => ObjectSelect::class,
            'attributes' => [
                'multiple' => true,
            ],
            'options' => [
                'object_manager' => $this->getObjectManager(),
                'target_class' => Status::class,
                'property' => 'name',
            ],
        ]);
    }
}

和行动

public function workflowEditAction()
{
    $sm = $this->getServiceLocator();
    $fm = $sm->get('FormElementManager');
    $om = $sm->get('Doctrine\ORM\EntityManager');

    $form = $fm->get(WorkflowForm::class);
    //$workflow = $om->getRepository(Status::class)->getStatusesByEntityId($route->getParam('id'));
    //$form->bind($workflow);

    return new ViewModel([
        'form' => $form,
    ]);
}

最后我想得到这样的东西

很抱歉代码太多了，我没有展示Hidrator，Factory和模板。

提前感谢大家的帮助。

经过一天的搜索，我解决了我的问题。主要的是需要生成数组来填充表单。

我用下一个结构创建数组

$values = array(4) {
  [0] => array(9) {
    ["id"] => int(99)
    ["name"] => string(6) "active"
    ["entityId"] => int(30)
    ["workflow"] => array(2) {
      [0] => int(100)
      [1] => int(101)
    }
  }
  [1] => array(9) {
    ["id"] => int(100)
    ["name"] => string(8) "inactive"
    ["entityId"] => int(30)
    ["workflow"] => array(0) {
    }
  }
  [2] => array(9) {
    ["id"] => int(101)
    ["name"] => string(6) "paused"
    ["entityId"] => int(30)
    ["workflow"] => array(1) {
      [0] => int(99)
    }
  }
}

填写$form->populateValues(['statuses' => $values]);

表格

接下来需要在存储库中创建自定义方法

public function getWorkflowByModule($module) {
    $moduleAlias = 'entity';
    $workflowAlias = 'workflow';
    $qb = $this->createQueryBuilder($this->_alias)
        ->select($this->_alias)
        ->leftJoin($this->_alias . '.workflow', $workflowAlias)
        ->leftJoin($this->_alias . '.entity', $moduleAlias);
    $qb->where($qb->expr()->eq($this->_alias . '.' . 'entity', $module->getId()));

    return $qb->getQuery()->getResult();
}

更改字段集中的选择

$this->add([
        'name' => 'workflow',
        'type' => ObjectSelect::class,
        'attributes' => [
            'multiple' => true,
        ],
        'options' => [
            'object_manager' => $this->getObjectManager(),
            'target_class' => Status::class,
            'property' => 'name',
            'is_method' => true,
            'find_method' => [
                'name' => 'getWorkflowByModule',
                'params' => [
                    'module' => $this->getModule(),
                ],
            ], 
        ],
    ]);

结果是我的预期

ZF2 Form / Doctrine ManyToMany自我介绍关系
