symfony 4-与ManyToMany关系的语义错误

Question

我已经与Symfony一起开始了一个项目，并且是该框架的初学者。通常，我可以通过阅读论坛和文档来纠正所有错误，但是在这种情况下，我无法理解该错误。

我有一个@objc(<name>)实体，具有许多WorkingTime关系：

ManyToMany

我想在该实体的存储库中创建一个自定义查询：

<?php

namespace App\Entity;

use App\Repository\WorkingTimeRepository;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass=WorkingTimeRepository::class)
 */
class WorkingTime
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\ManyToMany(targetEntity=User::class, inversedBy="workingTimes")
     */
    private $user;

    /**
     * @ORM\ManyToMany(targetEntity=Customer::class, inversedBy="workingTimes")
     */
    private $customer;

    /**

     */
    private $work;

    /**

     */
    private $workingPlace;

    /**

    private $createdAt;

    /**

        }

        return $this;
    }

    public function removeUser(User $user): self
    {
        if ($this->user->contains($user)) {
            $this->user->removeElement($user);

        return $this;

    public function setMeal(?int $meal): self
    {

        return $this;
    }
}

但是出现以下错误：

[语义错误]第0行，'name ASC'附近的col 85：错误：类App \ Entity \ WorkingTime没有名为customer.firstname的字段或关联

您可以看到我的客户实体

public function findByDate($date)
{
    return $this->createQueryBuilder('w')
        ->where('w.createdAt = :date')
        ->setParameter('date', $date)
        ->orderBy('w.customer.firstname', 'ASC')
        ->setMaxResults(10)
        ->getQuery()
        ->getResult()
    ;
}

Answer 1

您需要像这样加入客户：

public function findByDate($date)
{
    return $this->createQueryBuilder('w')
        ->join('w.customer', 'u')
        ->where('w.createdAt = :date')
        ->setParameter('date', $date)
        ->orderBy('u.firstname', 'ASC')
        ->setMaxResults(10)
        ->getQuery()
        ->getResult()
        ;
}
