Symfony 2.8：表单集合和一对多关系不能正确保持

时间：2017-04-26 08:40:51

标签： php forms doctrine one-to-many symfony-2.8

我需要在其父表单中嵌入一个实体表单。我跟随官方documentation将一张表格嵌入另一个与一对多关系的表格中。

问题是虽然我设法正确显示表单，但是当需要持久保存另一个子实体时，它可以正常使用前两个对象，当我尝试创建第三个对象时，它会删除数组中的第二个对象并创建第三个。

示例：我有一个与WorkExperience实体有一对多关系的CV实体

代码：

实体：

    class Curriculum
    {
        /**
        * @ORM\OneToMany(targetEntity="appBundle\Entity\WorkExperience", mappedBy="curriculum", cascade={"persist", "remove"}, orphanRemoval=true)
        */
        private $workExperience;

        public function __construct()
        {
            $this->workExperience = new \Doctrine\Common\Collections\ArrayCollection();
        }


     /**
     * Add workExperience
     *
     * @param appBundle\Entity\WorkExperience $workExperience
     * @return Curriculum
     */
    public function addWorkExperience(appBundle\Entity\WorkExperience $workExperience)
    {
        $this->workExperience->add($workExperience);
        $workExperience->setCurriculum($this);

        return $this;
    }

     /**
     * Remove workExperience
     *
     * @param appBundle\Entity\WorkExperience $workExperience
     */
    public function removeWorkExperience(appBundle\Entity\WorkExperience $workExperience)
    {
        $this->workExperience->removeElement($workExperience);
    }

     /**
     * Get workExperience
     *
     * @return \Doctrine\Common\Collections\Collection
     */
        public function getWorkExperience()
        {
            return $this->workExperience;
        }
}

WorkExperience：

class WorkExperience
{
    /**
     * @ORM\ManyToOne(targetEntity="appBundle\Entity\Curriculum", inversedBy="workExperience")
     * @ORM\JoinColumn(name="curriculum", referencedColumnName="id")
     */
    private $curriculum;

    /**
     * Set curriculum
     *
     * @param string $curriculum
     * @return WorkExperience
     */
    public function setCurriculum($curriculum)
    {
        $this->curriculum = $curriculum;

        return $this;
    }

    /**
     * Get curriculum
     *
     * @return string 
     */
    public function getCurriculum()
    {
        return $this->curriculum;
    }
}

然后，formType（我只创建了workExperience表单，因为它是我在collectionType字段中需要的）

WorkExperienceType：

<?php

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

        $builder
            ->add('fromDate', DateType::class, array(
                'widget' => 'single_text',
                'html5' => false,
                'attr' => ['class' => 'form-control js-datepicker'],
                'format' => 'dd-MM-yyyy',

            )
            ->add('toDate', DateType::class, array(
                'widget' => 'single_text',
                'html5' => false,
                'attr' => ['class' => 'form-control js-datepicker'],
                'format' => 'dd-MM-yyyy', 
                'label' => 'To',
                'required' => false,
                )
            )
            ->add('ongoing', 'checkbox', array('required' => false,))
            ->add('jobProfile', EntityType::class, array(
                'class' => 'appBundle:JobProfile',
                'query_builder' => function (EntityRepository $er) use ($options) {
                    return $er->createQueryBuilder('j')
                        ->where('j.company = :company')
                        ->setParameter('company', $options['company']);
                },
                'choice_label' => 'name',
                'required' => false,
                'placeholder' => 'Job Profile'
            ))
            ->add('employerName', 'text', array('label' => "Name"))
            ->add('employerCity', 'text', array('label' => "City"))
            ->add('activities', 'textarea', array('label' => "Activities and responsibilities"));
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefined('company');
        $resolver->setDefaults(array(
          'data_class' => WorkExperience::class,
        ));
    }
}

以下是截图，关键是它正确删除对象，唯一的问题是创建新对象时

1 个答案:

答案 0 :(得分：0)

有些事情似乎很奇怪。

  1. 使用$ form-＆gt; handleRequest（$ request）;而不是bind（）
  2. 你为什么使用＆＃39; type＆＃39; =＆GT;新的WorkExperience（）？我认为你不必在CollectionType字段中使用thois，因为实体的类型是在WorkexperienceTpe中定义的。
  3. 当您使用handlerequest函数发布表单时，您不需要从表单中检索所有数据，因为所有的工作经验都已自动添加到$ formCurriculum中
