Question

我用symfony生成了实体和表单，并试图创建一个简单的表单。但是我遇到了无法解决的错误。

试图调用类“ AppBundle \ Entity \ User”的名为“ createQueryBuilder”的未定义方法。

控制器：

public function groupedit(Request $request) {
    $group = new Group();
    $form = $this->createForm(GroupType::class, $group);

    $form->handleRequest($request);

    return $this->render(
                    'form.html.twig', array('form', $form->createView())
    );
}

用户YML

AppBundle\Entity\User:
  type: entity
  repositoryClass: User
  id:
    id:
      type: integer
      generator:
        strategy: AUTO

组表单类型

<?php

namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class GroupType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name')->add('systemgroup')->add('user');
    }/**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Entity\Group'
        ));
    }

    /**
     * {@inheritdoc}
     */
    public function getBlockPrefix()
    {
        return 'appbundle_group';
    }


}

有人知道问题出在哪里吗？

问题似乎出在您声明的实体映射中

repositoryClass: User

您应该传递有效的Doctrine存储库类而不是实体类。

因此，如果不需要自定义存储库功能，则从映射中删除repositoryClass或创建一个有效的类，该类应类似于以下内容：

namespace AppBundle\Repository;

use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository
{
    // your custom repository functions here
}

然后进行适当的映射

repositoryClass: AppBundle\Repository\UserRepository
