Symfony2错误提交表单与实体类型(多对多关系)

我在symfony2中创建了一个简单的多对多($ post - > $ category)关系,我想在我的表单构建器中使用,这要归功于“entity”字段类型,带有multiple = false选项(默认值) )就目前而言,尽管它有很多甚至很多。

这是我的Post实体的一部分:

 /**
 * @var ArrayCollection
 *
 * @ORM\ManyToMany(targetEntity="Yeomi\PostBundle\Entity\Category", inversedBy="posts")
 */
private $categories;



/**
 * Add categories
 *
 * @param \Yeomi\PostBundle\Entity\Category $categories
 * @return Post
 */
public function addCategory(\Yeomi\PostBundle\Entity\Category $category)
{
    $this->categories[] = $category;
    return $this;
}

/**
 * Remove categories
 *
 * @param \Yeomi\PostBundle\Entity\Category $categories
 */
public function removeCategory(\Yeomi\PostBundle\Entity\Category $category)
{
    $this->categories->removeElement($category);
}


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

这是我的PostType:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('title', 'text')
        ->add('content', 'textarea')
        ->add('published', 'checkbox')
        ->add("categories", "entity", array(
            "class" => "YeomiPostBundle:Category",
            "property" => "name",
            "multiple" => false,
        ))
        ->add('published', 'checkbox')
        ->add('save', "submit")
    ;
}

这是我得到的错误

  

500内部服务器错误 - NoSuchPropertyException

Neither the property "categories" nor one of the methods "addCategory()"/"removeCategory()", "setCategories()", "categories()", "__set()" or "__call()" exist and have public access in class "Yeomi\PostBundle\Entity\Post". 

它适用于multiple = true,但这不是我想要的,是不是因为关系是多对多,所以我被迫使它成为一个多实体字段?

我已经清除了缓存,doctrine缓存,我重新生成了我的实体getter / setter,不知道我可能做错了什么..

感谢您的帮助
