Symfony 3表格实体返回转换误差

Question

我的表格正在返回以下错误：

执行'Update user_info设置时发生了例外 country_of_residence =？，want_children =？，salary =？id =？' 使用params [{}，" a"，" 0"，22]：

可捕获的致命错误：类AppBundle Entity的对象 country可以 不转换为字符串

我的UserInfotype：

<?php
// src/AppBundle/Form/UserInfoType.php
namespace AppBundleForm;
use SymfonyComponentFormAbstractType;
use SymfonyComponentFormFormBuilderInterface;

class UserInfoType extends AbstractType

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('first_name', TextType::class, array('label' => 'Prénom'))

            ->add('save', SubmitType::class, array('label' => 'Suivant'))
        ;
    }

我的国家实体：

<?php
namespace AppBundleEntity;
use DoctrineORMMapping as ORM;
/**
 * Country
 *
 * @ORMTable(name="country")
 * @ORMEntity(repositoryClass="AppBundleRepositoryCountryRepository")
 */
class Country
{
    /**
     * @var int
     *
     * @ORMColumn(name="id", type="integer")
     * @ORMId

    private $language;

    /**

    public function getId()
    {
        return $this->id;
    }
    /**

    public function setCode($code)
    {
        $this->code = $code;
        return $this;
    }
    /**

     *
     * @return string

    public function getCode()
    {
        return $this->code;
    }
    /**

     * @param string $name
     *
     * @return Country
     */
    public function setName($name)
    {
        $this->name = $name;
        return $this;
    }
    /**
     * Get name
     *
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }
    /**
     * Set language
     *
     * @param string $language
     *
     * @return Country
     */
    public function setLanguage($language)
    {
        $this->language = $language;
        return $this;
    }
    /**
     * Get language
     *
     * @return string
     */
    public function getLanguage()
    {
        return $this->language;
    }
}

我的profil控制器：

/**
 * @Route("/survey/{slug}", name = "survey_render" )
 */
public function renderSurvey($slug, Request $request)
{
    $user = $this->getUser();   
    $em = $this->getDoctrine()->getManager();
    $user_info = $em->getRepository('ProfileBundle:UserInfo')->findOneBy(array('userId' => $user->getId()));
    if (!$user_info) {
        $user_info = new UserInfo();
        $user_info->setuserId($user->getId());
    }
    $user_pref = $em->getRepository('ProfileBundle:UserPreference')->findOneBy(array('userId' => $user->getId()));
    if (!$user_pref) {
        $user_pref = new UserPreference();
        $user_pref->setuserId($user->getId());
    }
    //$user_info = new UserInfo();
    switch ($slug) {
        case 'vos_infos':

            $form = $this->createForm(UserInfoType::class, $user_info );
            break;
        case 'votre_apparance':
            $form = $this->createForm(UserAppearanceType::class, $user_info);   
            break;
        case 'votre_style_vie':
            $form = $this->createForm(UserLifeStyleType::class, $user_info);    
            break;
        case 'ses_infos':
            $form = $this->createForm(UserPrefInfoType::class, $user_pref);
            break;
        case 'son_apparence':
            $form = $this->createForm(UserPrefAppearanceType::class, $user_pref);
            break;
        case 'son_style_vie':
            $form = $this->createForm(UserPrefLifeStyleType::class, $user_pref);
            break;
        case 'votre_quiz':
            $form = $this->createForm(UserLifeStyleType::class, $user_pref);
            break;
        default;
            echo 'Lien incorrect';
            break;
    }
    $form->handleRequest($request);
    if ($form->isSubmitted() && $form->isValid()) {
        $form_data = $form->getData();
        $em = $this->getDoctrine()->getManager();
        $em->persist($form_data);
        $em->flush();   

似乎试图将整个实体传递给表单，而不仅仅是选择结果。

有人知道我在这里做错了吗？

thx

Answer 1

好吧，我发现我在UserInfo中遇到的错误。

我没有预处@orm，也没有通往国家实体的正确途径（它不在同一名称空间中）

之前：

 /**
 * One Product has One Shipping.
 * @OneToOne(targetEntity="Country")
 * @JoinColumn(name="countryOfResidence", referencedColumnName="id")
 */
private $countryOfResidence;

之后：

/**
     * One Product has One Shipping.
     * @ORMOneToOne(targetEntity="AppBundleEntityCountry")
     * @ORMJoinColumn(name="countryOfResidence", referencedColumnName="id")
     */
    private $countryOfResidence;

感谢您将我指向正确的方向。

Answer 2

如果User_info是一个实体，您是否将field country_of_sordidess设置为国家实体的OneToOne关系？

Answer 3

我有相同类型的错误。就我而言，这是"拥有"实体中错误的注释。

befor （导致错误）：

/** 
 * @ORMOneToOne(targetEntity="RfpMatchBundleEntityAddress", cascade={"persist"})
 * @ORMColumn(nullable=true, unique=false)
 */
private $address;

之后（固定）：

/** 
 * @ORMOneToOne(targetEntity="RfpMatchBundleEntityAddress", cascade={"persist"})
 */
private $address;`
