我的UserInfoType：

我的国家实体：

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

     * @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();

似乎它试图将整个实体传递给表单，而不仅仅是选择结果。

有没有人知道我在这里做错了什么？

Answer 1

好的，我发现了UserInfo中的错误。

我没有预先安装@ORM并且没有到Country实体的正确路径（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;

后：

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

感谢您指出我正确的方向。

Answer 2

如果user_info是一个实体，您是否已将country_of_residence字段设置为国家/地区实体的onetoone关系？

Answer 3

我遇到了同样的错误。就我而言，它是“拥有”实体中的错误注释。

Befor （导致错误）：

/** 
 * @ORM\OneToOne(targetEntity="RfpMatchBundle\Entity\Address", cascade={"persist"})
 * @ORM\Column(nullable=true, unique=false)
 */
private $address;

<强>后（固定）：

/** 
 * @ORM\OneToOne(targetEntity="RfpMatchBundle\Entity\Address", cascade={"persist"})
 */
private $address;`
