ORO 平台 - 如何将相关实体的集合传递给数据网格列模板？

Question

我有一个实体与 ORO 平台中的相关实体。 Built-in User实体可以有多个built-in Access Roles。我想使用自定义树枝模板在用户数据网格中显示这些角色，以便我可以将它们包装在一些标签或样式中。

这是我的部分 datagrids.yaml，它覆盖了默认用户数据网格：

    users-grid:
        source:
            query:
                select:
                    - What to pass here?
                join:
                    left:
                        - { join: u.roles, alias: r }
                groupBy: u.id
        columns:
            roles:
                inline_editing:
                    enable: false
                label: 'Roles'
                type: twig
                frontend_type: html
                template: 'MyBundle:User:Property/roles.html.twig'

我需要做什么才能访问 roles.html.twig 中的 Role 对象集合？

仅使用 YAML 配置是不可能的。相反，您必须创建一个数据网格侦听器，它将使用“result after”事件上的数据填充角色列。这是一个例子：

AcmeDemoBundle/EventListener/UserRolesGridListener.php

<?php

namespace AcmeDemoBundle\EventListener;

use Oro\Bundle\DataGridBundle\Datasource\ResultRecord;
use Oro\Bundle\DataGridBundle\Event\OrmResultAfter;
use Oro\Bundle\EntityBundle\ORM\DoctrineHelper;
use Oro\Bundle\UserBundle\Entity\User;

class UserRolesGridListener
{
    /** @var DoctrineHelper */
    protected $doctrineHelper;

    /**
     * @param DoctrineHelper $doctrineHelper
     */
    public function __construct(DoctrineHelper $doctrineHelper)
    {
        $this->doctrineHelper = $doctrineHelper;
    }

    /**
     * @param OrmResultAfter $event
     */
    public function onResultAfter(OrmResultAfter $event)
    {
        $userIds = [];
        /** @var ResultRecord[] $records */
        $records = $event->getRecords();
        foreach ($records as $record) {
            $userIds[] = $record->getValue('id');
        }

        $repository = $this->doctrineHelper->getEntityRepository(User::class);
        $userRoles = $repository->createQueryBuilder('user')
            ->select('partial user.{id}, partial roles.{id, label}')
            ->indexBy('user','user.id')
            ->leftJoin('user.roles','roles')
            ->where('user.id in (:userIds)')
            ->setParameter('userIds', $userIds)
            ->getQuery()
            ->getArrayResult();
        foreach ($records as $record) {
            $id = $record->getValue('id');
            $record->addData(['roles' => $userRoles[$id]['roles']]);
        }
    }
}

AcmeDemoBundle/Resources/config/services.yml

services:
    AcmeDemoBundle\EventListener\UserRolesGridListener:
        arguments:
            - '@oro_entity.doctrine_helper'
        tags:
            - { name: kernel.event_listener, event: oro_datagrid.orm_datasource.result.after.users-grid, method: onResultAfter }

AcmeDemoBundle/Resources/config/oro/datagrids.yml

datagrids:
    users-grid:
        columns:
            roles:
                inline_editing:
                    enable: false
                label: 'Roles'
                type: twig
                frontend_type: html
                template: 'AcmeDemoBundle:User:Column/roles.html.twig'

AcmeDemoBundle/Resources/views/User/Column/roles.html.twig

{% for role in record.getValue('roles') %}
  <div class="role-{{ role.id }}">{{ role.label }}</div>
{% endfor %}
