Doctrine Entity Relationship - php

Question

Am having a bit of a challenge creating entity relationship between a product its Category and associated color(s) with the following Entities (I omitted the getters and setters though):
#Product
/**
* Product
*
* #ORM\Table(name="product")
* #ORM\Entity(repositoryClass="AppBundle\Repository\ProductRepository")
*/
class Product
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* #var float
*
* #ORM\Column(name="price", type="float")
*/
private $price;
/**
* #var int
*
* #ORM\Column(name="category", type="integer")
*
* Many Products have one category
*
* #ORM\ManyToOne(targetEntity="Category", inversedBy="products")
* #ORM\JoinColumn(name="category_id", referencedColumnName="id", nullable=false)
*/
protected $category;
/**
* #var int
*
* Many Products have one color
*
* #ORM\ManyToOne(targetEntity="Color", inversedBy="products")
* #ORM\JoinColumn(name="color_id", referencedColumnName="id")
*
* #ORM\Column(name="color", type="integer")
*/
private $color;
}
#Category
/**
* Category
*
* #ORM\Table(name="category")
* #ORM\Entity(repositoryClass="AppBundle\Repository\CategoryRepository")
*/
class Category
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=170, unique=true)
*/
private $name;
/**
* #var string
*
* #ORM\Column(name="desc", type="string", length=170, nullable=true)
*/
private $description;
/**
* One Category has many products assigned to it
*
* #ORM\OneToMany(targetEntity="Product", mappedBy="category", cascade={"persist"})
*/
private $products;
/**
* Class Constructor
*
* #param None
* #return void
**/
public function __construct()
{
$this->products = new ArrayCollection();
}
}
#Color
class Color{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="color", type="string", length=191, unique=true)
*/
private $color;
/**
* #var string
*
* #ORM\Column(name="code", type="string", length=191, unique=true)
*/
private $hexcode;
/**
* One Color has many products assigned to it
*
* #ORM\OneToMany(targetEntity="Product", mappedBy="color", cascade={"persist"})
*/
private $products;
/**
* Class Constructor
*
* #param none
* #return void
**/
public function _construct(){
$this->products = new ArrayCollection();
}
}
When I run:
* php bin/console doctrine:schema:validate:
I get the error messages:
* The association AppBundle\Entity\Category#products refers to the owning
side field AppBundle\Entity\Product#category which is not defined as
association, but as field.
* The association AppBundle\Entity\Category#products refers to the owning
side field AppBundle\Entity\Product#category which does not exist.
and:
* The association AppBundle\Entity\Color#products refers to the owning side
field AppBundle\Entity\Product#color which is not defined as association,
but as field.
* The association AppBundle\Entity\Color#products refers to the owning side
field AppBundle\Entity\Product#color which does not exist.
I noticed that whenever I comment out the lines:
** #ORM\Column(name="category", type="integer")
** #ORM\Column(name="color", type="integer")
The above errors vanish but I get a new message and error saying:
** [Mapping] OK - The mapping files are correct.
** [Database] FAIL - The database schema is not in sync with the current
mapping file.
What could i be doing wrong, am new to the doctrine concept, and i have followed the documentations. Any help would be appreciated...

For the Doctrine ORM the relations are not Integers but Entity objects.
Remove The #ORM\Column annotations from all fields with relations (in each entity).
Then update your database schema in development environment with:
php bin/console doctrine:schema:update --force
Then generate a doctrine migration file to execute on your production server
php bin/console doctrine:migrations:generate
Update the generetad migration file to your needs
And execute him by this way
php bin/console doctrine:migrations:execute timestampOfTheMigrateFile
