尝试删除文件时如何修复错误

标签： symfony vichuploaderbundle easyadmin

我正在创建一个网站，其中显示了我所做的项目。因此，当我添加一个新项目时，我不想自己修改数据库。因此，使用捆绑包easyAdmin，我创建了一个管理表单来管理它们。为了上传文件，我使用的是捆绑包vichuploader。到目前为止，没有问题，但是当我要删除该项目或修改文件时，出现此错误“在属性路径“名称”中给出了“字符串”，“ NULL”类型的预期参数。”

我什至不知道错误来自哪里。

包含文件的我的实体项目：

/**
 * @ORM\Entity(repositoryClass="App\Repository\ProjectRepository")
 * @ApiResource
 * @Vich\Uploadable
 */
class Project
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $name;

    /**
     * @Vich\UploadableField(mapping="projects", fileNameProperty="name")
     * @var File
     */
    private $projectFile;

    /**
     * @ORM\Column(type="string", length=255)
     */
    private $url;

    /**
     * @ORM\Column(type="datetime")
     */
    private $updateAt;

    public function __construct()
    {
    }

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

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

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

        return $this;
    }

    public function getUrl(): ?string
    {
        return $this->url;
    }

    public function setUrl(string $url): self
    {
        $this->url = $url;

        return $this;
    }

    public function __toString()
    {
        return $this->nom;
    }

    public function getProjectFile()
    {
        return $this->projectFile;
    }

    public function setProjectFile(File $projectFile = null)
    {
        $this->projectFile = $projectFile;

        if ($projectFile) {
            $this->updateAt = new DateTime('now');
            $this->url = '%app.path.projects%' . $this->name;
        }
    }

    public function getUpdateAt(): ?\DateTimeInterface
    {
        return $this->updateAt;
    }

    public function setUpdateAt(\DateTimeInterface $updateAt): self
    {
        $this->updateAt = $updateAt;

        return $this;
    }


}

我的easy_admin.yaml文件：

easy_admin:
    entities:
        # List the entity class name you want to manage
        Project:
            class: App\Entity\Project
            form:
                fields:
                    - { property: 'name' }
                    - { property: 'projectFile', type: 'file' }

我的services.yaml文件：

parameters:
    locale: 'fr'
    app.path.projects: /projects

我的vich_uploader.yaml文件：

vich_uploader:
    db_driver: orm

    mappings:
        projects:
            uri_prefix: '%app.path.projects%'
            upload_destination: '%kernel.project_dir%/public%app.path.projects%'

这是我遇到的错误：

3 个答案:

答案 0 :(得分：0)

您的项目对象有名称吗？听起来像$ project-> getName（）为空。

答案 1 :(得分：0)

 /**
 * @ORM\Column(type="string", length=255, nullable=true)
 */
private $name;

您可以尝试为“名称”添加“ nullable = true”

答案 2 :(得分：0)

如果您不将public function setName(string $name)更改为public function setName(string $name = null)，则

nullable = true不会有帮助，这样做甚至可以删除nullable = true
