用 vich_image onetone 保存表格

Question

/**
 * @Gedmo\Tree(type="nested")
 * @ORM\Table(name="mKeyword")
 * @ORM\Entity(repositoryClass="KeywordRepository")
 */
class Keyword {

 /**
     * @ORM\OneToOne(targetEntity="Image",mappedBy="keyword" ,cascade={"all"})
     * @var Image
     */
    private $logo;
}

/**
 * @Vich\Uploadable
 * @ORM\Entity
 * @ORM\Table(name="mKeywordLogo")
 */
class Image {
}

表格

class KeywordType extends AbstractType{
public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder
        ->add('title','text')
        ->add('logo',new ImageType())

图像形式

class ImageType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('file','vich_image',array(
        'label'=>'logo'
    ));

}

保存表格时得到

Expected value of type "KeywordsBundle\Entity\Image" for association field "Mea\KeywordsBundle\Entity\Keyword#$logo", got "array" instead.

我在关键字中添加数组解析器

  public function setLogo($logo)
    {

        if(is_array($logo))
            $logo = reset($logo);
        $this->logo = $logo;
    }

所以报错

关联字段 "KeywordsBundle\Entity\Keyword#$logo" 类型 "KeywordsBundle\Entity\Image" 的预期值，得到的是 "Symfony\Component\HttpFoundation\File\UploadedFile"。

我发现错误，当我添加这个时，Form ImageType 没有默认值。保存工作正常

   /**
     * @param OptionsResolverInterface $resolver
     */
    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Mea\KeywordsBundle\Entity\Image'
        ));
    }
