Doctrine Select - 如何选择特定用户数据

所以我在用户表和用户债权人之间有一对多的关联。在编写报告时,用户需要选择要连接的债权人。我遇到的问题是我想只返回使用DoctrineSelect的登录用户债权人而不是数据库中的每个债权人。我不确定如何将DoctrineSelect限制为登录用户的ID。

这是我到目前为止所做的:

客户 - >债权人

在我的字段集中,我有以下内容:

    $this->add(
        [
            'type' => 'DoctrineModule\Form\Element\ObjectSelect',
            'name' => 'creditor',
            'options' => [
                'object_manager' => $this->objectManager,
                'target_class'   => 'Debtor\Entity\Creditor',

                'label_generator' => function($targetEntity) {
                        return $targetEntity->getTitle() . ' - ' . $targetEntity->getFirstName() . ' - ' . $targetEntity->getLastName();
                    },
                'label' => 'Creditor',
                'instructions' => 'Attach creditors to this report'

            ],
            'attributes' => [
                'multiple' => true,
                'required' => 'required',
            ]
        ]
    );

不幸的是,这会将所有债权人附加到与用户相关的表格中。

为了解决这个问题,我创建了以下类:

<?php
namespace Application\Form;
use Debtor\Service\CreditorService;
use Zend\Form\View\Helper\FormElement as BaseFormElement;
use Zend\Form\ElementInterface;

class FormElement extends BaseFormElement
{
    public function __construct(
        CreditorService $creditorService
    )
    {
        $this->creditorService = $creditorService;
    }

    /**
     * This function overrides the ZendFormElement method which allows us to set the format of our own elements if required
     * @param ElementInterface $element
     * @return string
     */
    public function render( ElementInterface $element )
    {

        $attributes = $element->getAttributes();

        if ( isset( $attributes['customElement']) )
        {
            $customElement = $attributes['customElement'];

            switch( $customElement ) {

                case 'getCreditors':
                    $creditors = $this->creditorService->findUserCreditors();
                    $element->setValueOptions( $creditors );
                    break;
            }
        }

        return parent::render($element);
    }
}

在我的字段集中,我现在有了这个:

$this->add(
            [
                'type' => 'select',
                'name' => 'creditor',
                'options' => [
                    'label' => 'Creditor',
                    'instructions' => 'Attach creditors to this report',
                ],
                'attributes' => [
                    'multiple' => true,
                    'required' => 'required',
                    'class' => 'form-control input-medium select2me',
                    'customElement' => 'getCreditors',  <-*****************
                ]
            ]
        );

我的班级在哪里查找customElement,如果发现它在我的债权人服务中使用以下代码返回客户债权人:

 /**
     * @return array
     */
    public function findUserCreditors()
    {
        $creditors = $this->findByUserAuth();
        $creditorArray = [];

        foreach ($creditors AS $creditorObject)
        {
            $creditorArray[$creditorObject->getId()] = $creditorObject->getName();
        }

        return $creditorArray;

    }

这可以解决一个小问题。编辑报表时,表单不会在下拉列表中预先选择先前选择的债权人...

我的问题是:

有没有办法使用DoctrineSelect并使用我的AuthenticationService,获取登录的用户ID并返回特定数据?

这是我的解决方案。

使用here中的示例3和此post的建议。

我做了以下事情:

  1. 创建了一个存储库
  2. 将我的身份验证服务注入到我的表单中,并将authService作为现场的参数包含在内。
  3. 我的字段集:

        $this->add(
            [
                'type' => 'DoctrineModule\Form\Element\ObjectSelect',
                'name' => 'creditor',
                'options' => [
                    'label' => 'Creditor: ',
                    'object_manager' => $this->objectManager,
                    'target_class' => 'Debtor\Entity\Report',
                    'property' => 'Report',
                    'is_method' => true,
                    'find_method' => [
                        'name' => 'findUserCreditors',
                        'params' => [
                            'authService' => $this->authService
                        ],
                    ]
                ],
                'attributes' => [
                    'multiple' => true,
                    'required' => 'required',
                    'class' => 'form-control input-medium select2me',
                ]
            ]
        );
    

    通过更新注释,为我的报告实体添加了一个存储库:

    /**
     * @ORM\Entity(repositoryClass="CustomRepository")
     * @ORM\Table(name="report")
     */
    class Report
    {
    

    最后添加了存储库类:

    <?php
    namespace Debtor\Entity;
    
    use Customer\Service\AuthenticationService;
    use Doctrine\ORM\EntityRepository;
    
    class CreditorRepository extends EntityRepository
    {
        public function findUserCreditors(AuthenticationService $authService)
        {
            $userObject = $authService->getIdentity();
    
            $qb = $this->createQueryBuilder('c')
                ->orderBy('c.created', 'ASC');
    
            $qb->where('c.user = :user')
                ->setParameter('user' , $userObject );
    
            $result = $qb->getQuery()->getResult();
    
            return $result;
        }
    } 
    

    如果您遇到困难或收到错误,请转储存储库数据并确保它返回正确的对象。
