未找到字段"图像"映射vichupolader symfony2 - Mapping not found for field "image" vichupolader symfony2

我试图在图像实体和用户实体之间建立一个OneToOne关系，就像这样:

图片:

    /**
 * Image
 *
 * @ORM'Table(name="image")
 * @ORM'Entity(repositoryClass="SocialNetworkBundle'Repository'ImageRepository")
 * @Vich'Uploadable 
 */
class Image {
    /**
     * @var int
     *
     * @ORM'Column(name="id", type="integer")
     * @ORM'Id
     * @ORM'GeneratedValue(strategy="AUTO")
     */
    private $id;
    /**
     * Get id
     *
     * @return int
     */
    public function getId() {
        return $this->id;
    }
    /**
     * NOTE: This is not a mapped field of entity metadata, just a simple property.
     * 
     * @Vich'UploadableField(mapping="user_image", fileNameProperty="imageName")
     * @Assert'File(
     *     maxSize = "1024k",
     *     mimeTypes = {"image/png", "image/jpeg", "image/jpg"},
     *     mimeTypesMessage = "Please upload a valid PDF or valid IMAGE"
     * )
     * 
     * @var File
     */
    private $imageFile;
    /**
     * @ORM'Column(type="string", length=255, nullable=true)
     *
     * @var string
     */
    private $imageName;
    /**
     * Set imageName
     *
     * @param string $imageName
     *
     * @return Image
     */
    public function setImageName($imageName) {
        $this->imageName = $imageName;
        return $this;
    }
    /**
     * Get imageName
     *
     * @return string
     */
    public function getImageName() {
        return $this->imageName;
    }
}

用户:

    /**
 * User
 *
 * @ORM'Table(name="user")
 * @ORM'Entity(repositoryClass="UserBundle'Repository'UserRepository") 
 * @Vich'Uploadable
 */
class User extends BaseUser {
    /**
     * @var int
     *
     * @ORM'Column(name="id", type="integer")
     * @ORM'Id
     * @ORM'GeneratedValue(strategy="AUTO")
     */
    protected $id;
    /**
     * @var string
     *
     * @ORM'Column(name="name", type="string", length=255, unique=false)
     * @Assert'Length(min=2, max=100)
     */
    private $name;
    /**
     * @ORM'OneToOne(targetEntity="SocialNetworkBundle'Entity'Image", cascade={"persist", "merge", "remove"})
     * @ORM'JoinColumn(name="image_id", referencedColumnName="id")
     * @Assert'Valid()
     */
    private $image;
    /**
     * Set name
     *
     * @param string $name
     *
     * @return User
     */
    public function setName($name) {
        $this->name = $name;
        return $this;
    }
    /**
     * Get name
     *
     * @return string
     */
    public function getName() {
        return $this->name;
    }
    /**
     * Set image
     *
     * @param 'SocialNetworkBundle'Entity'Image $image
     *
     * @return User
     */
    public function setImage('SocialNetworkBundle'Entity'Image $image = null) {
        $this->image = $image;
        return $this;
    }
    /**
     * Get image
     *
     * @return 'SocialNetworkBundle'Entity'Image
     */
    public function getImage() {
        return $this->image;
    }
}

和用户的表单生成器:

    class RegistrationFormType extends BaseType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        parent::buildForm($builder, $options);
        // add your custom field
        $builder->add('name')
             ->add('roles', 'collection', array(
               'type' => 'choice',
               'options' => array(
               'choices' => array(
                   'ROLE_ADMIN' => 'Admin'))))
                ->add('image', VichFileType::class, array(
                    'required' => false,
                    'allow_delete' => true, // not mandatory, default is true
                    'download_link' => true, // not mandatory, default is true
                    ))
                ;
    }
    public function getName()
    {
        return 'user_registration';
    }
}

这个错误出现在我:

字段"image"找不到映射

如何解决

不需要为User类添加@Vich'Uploadable，您可以删除该注释。

在形式类型RegistrationFormType图像不是类型Vich'Uploadable，你应该创建一个形式类型的Image类，让我们称之为ImageType为例，并添加到它:

  $builder->add('name')
      ->add('image', VichFileType::class, array(
            'required' => false,
            'allow_delete' => true, // not mandatory, default is true
            'download_link' => true, // not mandatory, default is true
            ))
        ;

在RegistrationFormType中引用您的图像类型:
```
 ->add('image', new ImageType(),array(...))
```
