参数必须是类型 ?array, string given, called in doctrine/annotations/lib/Doctrine/Common/Annotations/DocParser.php Annotations/DocParser.php

Question

我不明白我在 API 平台上的错误。

Doctrine\ORM\Mapping\ManyToOne::__construct(): 参数 #2 ($cascade) 必须是类型 ?array, string given, called in /Users/charleslem/symfony/API-plateform-php-8/Api-plateform-php8-symfony5/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/DocParser.php在第 944 行。

什么参数错误再说。我没有指示。

我的代码：

第一个实体：


namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use App\Repository\PostRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Validator\Constraints\Length;

    public function getId(): ?int

    public function getTitle(): ?string

    }

    public function setTitle(string $title): self

}

我的第二个实体：


namespace App\Entity;

use ApiPlatform\Core\Annotation\ApiResource;
use App\Repository\CategoryRepository;

use Doctrine\Common\Collections\Collection;

    private $name;

    /**

        $this->posts = new ArrayCollection();
    }

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getName(): ?string
    {
        return $this->name;
    }

    public function setName(string $name): self
    {
        $this->name = $name;

        return $this;
    }

    /**

    public function getPosts(): Collection
    {
        return $this->posts;
    }

    public function addPost(Post $post): self
    {
        if (!$this->posts->contains($post)) {
            $this->posts[] = $post;
            $post->setCategory($this);
        }

        return $this;
    }

    public function removePost(Post $post): self
    {
        if ($this->posts->removeElement($post)) {
            // set the owning side to null (unless already changed)
            if ($post->getCategory() === $this) {

            }
        }

        return $this;
    }
}

Answer 1

在您的注释中，您定义了一个 ManyToOne 关系并尝试将 cascade 选项设置为一个字符串值：

/**
 * @ORM\ManyToOne(targetEntity=Category::class, inversedBy="posts", cascade="persiste")
 */

正如错误明确指出的那样，它应该是一个数组：

/**
 * @ORM\ManyToOne(targetEntity=Category::class, inversedBy="posts", cascade={"persist"})
 */

参数必须是类型 ?array, string given, called in doctrine/annotations/lib/Doctrine/Common/Annotations/DocParser.php Annotations/DocParser.php

Argument must be of type ?array, string given, called in doctrine/annotations/lib/Doctrine/Common/Annotations/DocParser.php Annotations/DocParser.php
