Question

我有实体技能和语言有关系ManyToMany。

我创造技能并选择语言我在我的表中看到了很多很多id技能和id语言，但是当我创建语言并选择技能时，我没有新的行技能表语言，但是在刷新后我有：< / p>

$afetr_skills = $entity->getSkills()->getValues();

有技巧，但我没有在DB的表格中看到这一点。我做错了什么？请帮助。

我的实体：

class CodeDirectoryProgramLanguages
{
use Timestampable;
/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var string
 *
 * @ORM\Column(name="languages", type="string", length=255)
 */
private $languages;

/**
 * @ORM\ManyToMany(targetEntity="Artel\ProfileBundle\Entity\Skill", mappedBy="language", cascade={"persist", "remove"})
 */
protected $skills;

和技能：

class Skill
{
use Timestampable;
/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var string
 *
 * @ORM\Column(name="skill", type="string", length=255)
 */
private $skill;

/**
 * @var \Artel\ProfileBundle\Entity\CodeDirectoryProgramLanguages
 *
 * @ORM\ManyToMany(targetEntity="CodeDirectoryProgramLanguages", inversedBy="skills", cascade={"persist", "remove"})
 */
protected $language;

和表单添加语言：

    public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('languages',  'text', array('label' => 'Skill Name'));

            $builder->add('skills','entity',
                array(
                    'class'=>'Artel\ProfileBundle\Entity\Skill',
                    'property'=>'skill',
                    'multiple'=>true,
                    'expanded' => true,
                     )
            );

    $builder
    ->add('save','submit')
    ;
}

和我的行动：

    public function newLanguageAction(Request $request)
{
    $em = $this->getDoctrine()->getManager();
    $entity = new CodeDirectoryProgramLanguages();
    $form = $this->createForm(new LanguageType(), $entity);
    $form->submit($request);
    if ($request->isMethod('POST')) {

        if ($form->isValid()) {

            $em->persist($entity);
            $em->flush();
            $skills = $entity->getSkills()->getValues();

            if(!empty($skills)){
                foreach($skills as $skill){
                    $skill->removeLanguage($entity);
                    $em->persist($skill);
                    $em->flush();
                }
            }

            if(!empty($form_skills)){
                foreach($form_skills as $skill){
                    $skill->addLanguage($entity);
                    $em->persist($skill);
                    $em->flush();
                }
            }
        }
            return $this->redirect($this->generateUrl('languages_show'));
        }
    }

    return array(
        'debug' => true,
        'form'      => $form->createView(),
    );
}

当我编辑实体时，我首先删除所有技能，然后按表单添加技能，但我知道这很糟糕。如何在学说中使用这种关系并在DB中设置？
