条令选择-如何选择特定用户的数据


Doctrine Select - how to select specific users data

所以我在用户表和用户债权人之间有一个一对多的关联。在编写报告时,用户需要选择要连接到他或她的债权人中的哪一个。我遇到的问题是,我只想使用DoctrineSelect返回登录的用户债权人,而不是数据库中的每个债权人。我不知道如何将DoctrineSelect限制为登录用户的ID。

这就是我迄今为止所做的:

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,这将所有债权人都附加到了属于用户的表格中。

因此,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);
    }
}

在我的领域中,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',  <-*****************
                ]
            ]
        );

在我的类查找customElement的地方,如果找到它,它会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;
    }

这是对一个小问题的处理。当我编辑报告时,表单不会在下拉列表中预先选择以前选择的债权人。。。

我的问题是:

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

这是我的解决方案。

使用这里的示例3和本文的建议。

我做了以下工作:

  1. 创建了存储库
  2. 将我的auth服务注入到我的表单中,并将authService作为参数包含在字段中

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',
            ]
        ]
    );

并通过更新注释向我的报告实体添加了一个存储库,如下所示:

/**
 * @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;
    }
} 

如果您遇到困难或出现错误,请转储存储库数据,并确保它返回正确的对象。
