Question

在表单中保存数据后，我一直收到以下错误：

属性“类别”也不是其中一种方法 “addCategory（）”/“removeCategory（）”，“setCategories（）”，“categories（）”， “__set（）”或“__call（）”存在并且在课堂上具有公共访问权限 “APW \ BlackbullBundle \实体\产品”。

我有5个表：产品，ProductsDescption，Categories，CategoriesDescription和ProductstoCategories。但我不断收到上述错误。

我有以下表单构建器：

任何想法？哪里错了？

Answer 1

我遇到了类似的问题，并且能够通过添加＆＃39; multiple＆＃39;来修复它。 =＆GT;是的，您还可以选择添加＆＃39;展开＆＃39; =＆GT;如果您想使用复选框，则为TRUE 。

Answer 2

您在“产品表单类型”中将categories设置为ApwBlackbullBundle:CategoriesDescription：

        ->add('categories', 'entity', array(
                                        'class'       => 'ApwBlackbullBundle:CategoriesDescription', // your problem
                                        'property'    => 'categoriesName',
                                        'empty_value' => 'Scegliere una categoria',
                                        'required'    => false,
                                        'label'       => 'Crea in:'))

但您的Product实体使用ApwBlackbullBundle:Categories：

/**
 * @ORM\ManyToMany(targetEntity="Categories", inversedBy="products")
 * @ORM\JoinTable(name="productstocategories")
 */
private $categories;

并且是\Apw\BlackbullBundle\Entity\Categories的类型提示：

/**
 * Add categories
 *
 * @param \Apw\BlackbullBundle\Entity\Categories $categories
 * @return Products
 */
public function addCategory(\Apw\BlackbullBundle\Entity\Categories $categories)
{
    $this->categories[] = $categories;

    return $this;
}

/**
 * Remove categories
 *
 * @param \Apw\BlackbullBundle\Entity\Categories $categories
 */
public function removeCategory(\Apw\BlackbullBundle\Entity\Categories $categories)
{
    $this->categories->removeElement($categories);
}

这些需要匹配您的表格才能正常运行。可能的解决方案是将第一个引用的代码段中的'class' => 'ApwBlackbullBundle:CategoriesDescription'更改为'class' => 'ApwBlackbullBundle:Categories'。
