Invalid Entities Category And Product - symfony

Question

I have 2 entities - Product and category.
But i have in symfony dev toolbar the error - Invalid Entities 2.
The exact error is:
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
I've tried many times fix the relastion following symfony docs, but it dosn't works.
So, please, tell were am i wrong....
Here are my 2 entities:

How to fix it?

Answer 1

Try replacing in Product entity this
private $categoryId;
By this
private $category;
Don't forget to change the getter & setter

Answer 2

try to change this:
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\category", inversedBy="product")
to this:
* #ORM\ManyToOne(targetEntity="Category", inversedBy="products")
and this:
* #ORM\OneToMany(targetEntity="AppBundle\Entity\Product" , mappedBy="category")
to this:
* #ORM\OneToMany(targetEntity="Product" , mappedBy="category")
