我有2个实体 - 产品和类别。但我在symfony dev工具栏中出现错误 - 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后的relastion，但它不起作用。
那么，请告诉我哪里错了....
这是我的两个实体：
产品

怎么解决？
尝试在此实体中替换
private $categoryId;
这样
private $category;
不要忘记更改吸气剂和定位器
试着改变这个：
* @ORM\ManyToOne(targetEntity="AppBundle\Entity\category", inversedBy="product")
对此：
* @ORM\ManyToOne(targetEntity="Category", inversedBy="products")
还有这个：
* @ORM\OneToMany(targetEntity="AppBundle\Entity\Product" , mappedBy="category")
对此：
* @ORM\OneToMany(targetEntity="Product" , mappedBy="category")
