Question

我从symfony开始，我想创建一个多客户端应用程序。我希望每次表都有与我公司表的链接时，根据所连接用户的所属公司自动过滤我的SQL查询内容。

我找到了创建过滤器的方法，但我找不到在此过滤器中检索有关已连接用户公司的信息的方法。

我使用FOSuser我用我自己的User类覆盖它。

我的config.yml

#app\config\config.yml

    doctrine:
        dbal:
           ...
        orm:
            auto_generate_proxy_classes: '%kernel.debug%'
            naming_strategy: doctrine.orm.naming_strategy.underscore
            auto_mapping: true
            filters:
                company:
                    class: 'Acme\CompanyBundle\Repository\Filters\CompanyFilter'
                    enabled: true

我的过滤器

<?php
#src\Acme\CompanyBundle\Repository\Filters\CompanyFilter.php

namespace Acme\CompanyBundle\Repository\Filters;

use Doctrine\ORM\Mapping\ClassMetaData;
use Doctrine\ORM\Query\Filter\SQLFilter;
use Acme\UserBundle\Entity\UserEntity;
use Acme\CompanyBundle\Entity\CompanyEntity;

class CompanyFilter extends SQLFilter
{
    public function addFilterConstraint(ClassMetadata $targetEntity, $targetTableAlias)
    {
        if ($targetEntity->hasAssociation("company")) {

            // here how to get the connected user ???

            $company = $user->getCompany();
            $idCompany = $company->getId();
            return $targetTableAlias . ".company_id = '".$idCompany."'";


        }
        return "";
    }
}

提前感谢您的帮助

设置onKernelRequest侦听器，将令牌存储服务传递给它，以便将用户定义为SQLFilter的参数。

所以在你的services.yml中添加：

services:
    on_request_listener:
        class: Acme\CompanyBundle\EventListener\OnRequestListener
        arguments: ["@doctrine.orm.entity_manager", "@security.token_storage"]
        tags:
            -
                name: kernel.event_listener
                event: kernel.request
                method: onKernelRequest

创建监听器：

class OnRequestListener
{
    protected $em;
    protected $tokenStorage;

    public function __construct($em, $tokenStorage)
    {
        $this->em = $em;
        $this->tokenStorage = $tokenStorage;
    }
    public function onKernelRequest(GetResponseEvent $event)
    {
        if($this->tokenStorage->getToken()) {
            $user = $this->tokenStorage->getToken()->getUser();
            $filter = $this->em->getFilters()->enable('company');
            $filter->setParameter('user', $user);
        }
    }
}

然后最后你的SQLFilter：

<?php
#src\Acme\CompanyBundle\Repository\Filters\CompanyFilter.php

namespace Acme\CompanyBundle\Repository\Filters;

use Doctrine\ORM\Mapping\ClassMetaData;
use Doctrine\ORM\Query\Filter\SQLFilter;
use Acme\UserBundle\Entity\UserEntity;
use Acme\CompanyBundle\Entity\CompanyEntity;

class CompanyFilter extends SQLFilter
{
    public function addFilterConstraint(ClassMetadata $targetEntity, $targetTableAlias)
    {
        if ($targetEntity->hasAssociation("company") && $this->hasParameter('user')) {

            $user = $this->getParameter('user');

            $company = $user->getCompany();
            $idCompany = $company->getId();
            return $targetTableAlias . ".company_id = '".$idCompany."'";


        }
        return "";
    }
}

在Symfony 3中的SQLFilter中获取用户
