我有2个实体 - 产品和类别。 但我在symfony开发工具栏中有错误 - 无效实体2.
确切的错误是：
Entities Mapping
Class Mapping errors
AppBundle\Entity\category
The association AppBundle\Entity\category#products refers to the owning side field AppBundle\Entity\Product#category which does not exist.
AppBundle\Entity\Product
The association AppBundle\Entity\Product#categoryId refers to the inverse side field AppBundle\Entity\category#product which does not exist.here
我已经多次尝试修复symfony docs之后的版本，但它不起作用。
所以，请告诉我，我错了......
以下是我的2个实体：
产品

如何解决？
答案 0 :(得分：0)
尝试替换此产品实体
private $categoryId;
通过这个
private $category;
不要忘记改变吸气剂和吸气剂设定器
答案 1 :(得分：0)
尝试改变这个：
* @ORM\ManyToOne(targetEntity="AppBundle\Entity\category", inversedBy="product")
到此：
* @ORM\ManyToOne(targetEntity="Category", inversedBy="products")
和此：
* @ORM\OneToMany(targetEntity="AppBundle\Entity\Product" , mappedBy="category")
到此：
* @ORM\OneToMany(targetEntity="Product" , mappedBy="category")
