我有一个问题,我不知道如何修复它。我正在为网络上的类别做一个CRUD。
我们可以有2种类型的类别,categorieParent
和每个Categorie
具有一个categorieParent
。
我已经使用 make:form
mae crud,但是当我提交表格时,出现以下错误:
类型"整数或null"类型的预期论点, 在属性路径上给出的" app entity epcorieparent" " epcorie_parent_id"。
这是我的实体:

你能解释一下我出了什么问题吗?非常感谢。
查看此部分:
/**
* @ORMManyToOne(targetEntity="AppEntityCategorieParent", inversedBy="categorie_id")
*/
private $categorie_parent_id;
当您的属性名称为 categorie_parent_id
时,它不会返回ID。学说将该字段水合成一个对象。它将改为返回CategorieParent
对象(或null
(。考虑删除此属性名称的_id
部分,因为它不容易容纳整数,而是一个对象。
更新您的方法:
public function getCategorieParentId(): ?CategorieParent
{
return $this->categorie_parent_id;
}
public function setCategorieParentId(?CategorieParent $categorie_parent_id): self
{
$this->categorie_parent_id = $categorie_parent_id;
return $this;
}
