Question

尝试在表单中使用实体字段类型时出现上述错误。

我使用的是Symfony 2.6.0。

我的班级有一个类别字段，定义为：

/**
     * @ORM\ManyToOne(targetEntity="Category", inversedBy="parent")
     * @ORM\JoinColumn(name="category_id", referencedColumnName="id")
     */
    protected $category;

类别类定义为：

/**
 * @ORM\OneToMany(targetEntity="Parent", mappedBy="category")
 */
protected $parents;

我的表单类型定义了类别：

->add('category', 'entity', array(
                'class' => 'AppBundle:Category',
                'property' => 'name'

在我的控制器中，我用它来调用它：

->add('category', 'entity')

堆栈跟踪如下：

非常感谢任何帮助。

看起来您已经创建了一个表单类，但是在控制器中重新创建表单而不是使用表单类。

在我的控制器中，我称之为： ->add('category', 'entity')

您应该使用与表单类相同的class和property选项，或者更好，使用控制器中的表单类而不是重新创建表单。

$this->createForm(new ParentType(), $parent);

MissingOptionsException：缺少必需的选项“class”
