Extend Product entity

Hello,
I need to extend Product Entity:

PHP

/** * {@inheritdoc} */ public function up(Schema $schema, QueryBag $queries) { $this->extendExtension->addOneToManyRelation( $schema, 'oro_product', 'attribute', 'product_attribute_value_varchar', ['value'], ['value'], ['value'], ['extend' => ['owner' => ExtendScope::OWNER_CUSTOM, 'without_default' => true]] ); }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

/**      * {@inheritdoc}      */     public function up(Schema $schema, QueryBag $queries)     {         $this->extendExtension->addOneToManyRelation(             $schema,             'oro_product',             'attribute',             'product_attribute_value_varchar',             ['value'],             ['value'],             ['value'],             ['extend' => ['owner' => ExtendScope::OWNER_CUSTOM, 'without_default' => true]]         );     }

Entity:

PHP

/** * @ORM\Entity() * @ORM\Table(name="product_attribute_value_varchar") * @Config */ class ProductAttributeValueVarchar { /** * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") * @ORM\Column(type="integer") */ private $id; /** * @var ProductAttribute * * @ORM\ManyToOne(targetEntity="Divante\Bundle\ProductAttributeBundle\Entity\ProductAttribute") * @ORM\JoinColumn(name="prod_attr_id", referencedColumnName="id", onDelete="SET NULL") */ private $attribute; /** * @ORM\Column(type="string") */ private $value; /** * @return mixed */ public function getId() { return $this->id; } /** * @param mixed $id */ public function setId($id) { $this->id = $id; } /** * @return mixed */ public function getAttribute() { return $this->attribute; } /** * @param mixed $attribute */ public function setAttribute($attribute) { $this->attribute = $attribute; } /** * @return mixed */ public function getValue() { return $this->value; } /** * @param mixed $value */ public function setValue($value) { $this->value = $value; } }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75

/** * @ORM\Entity() * @ORM\Table(name="product_attribute_value_varchar") * @Config */ class ProductAttributeValueVarchar {     /**      * @ORM\Id      * @ORM\GeneratedValue(strategy="AUTO")      * @ORM\Column(type="integer")      */     private $id;       /**      * @var ProductAttribute      *      * @ORM\ManyToOne(targetEntity="Divante\Bundle\ProductAttributeBundle\Entity\ProductAttribute")      * @ORM\JoinColumn(name="prod_attr_id", referencedColumnName="id", onDelete="SET NULL")      */     private $attribute;       /**      * @ORM\Column(type="string")      */     private $value;       /**      * @return mixed      */     public function getId()     {         return $this->id;     }       /**      * @param mixed $id      */     public function setId($id)     {         $this->id = $id;     }       /**      * @return mixed      */     public function getAttribute()     {         return $this->attribute;     }       /**      * @param mixed $attribute      */     public function setAttribute($attribute)     {         $this->attribute = $attribute;     }       /**      * @return mixed      */     public function getValue()     {         return $this->value;     }       /**      * @param mixed $value      */     public function setValue($value)     {         $this->value = $value;     } }

After $product->getAttribute(), and collection init, a get an error:

PHP

Undefined index: product_attribute in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/Entity/BasicEntityPersister.php on line 1768 PHP Warning: Invalid argument supplied for foreach() in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Persisters/Entity/BasicEntityPersister.php on line 1773 PHP Notice: Undefined index: product_attribute in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/PersistentCollection.php on line 169 [Symfony\Component\Debug\Exception\FatalThrowableError] Call to a member function setValue() on null

It is the bidirectional relation then we should add to our Entity class something like that:

PHP

/** * @ORM\ManyToOne(targetEntity="Oro\Bundle\ProductBundle\Entity\Product") * @ORM\JoinColumn(name="product_attribute_id", referencedColumnName="id", onDelete="SET NULL") */ private $product_attribute;

1 2 3 4 5

/** * @ORM\ManyToOne(targetEntity="Oro\Bundle\ProductBundle\Entity\Product") * @ORM\JoinColumn(name="product_attribute_id", referencedColumnName="id", onDelete="SET NULL") */ private $product_attribute;

And getter, setter for it.

After we can get all records from product object:

PHP

$product->getAttribute()

1	$product->getAttribute()
