Doctrine OneToMany relationship error
doctrine-orm, many-to-one, one-to-many, symfony
Solution
Your annotations' syntax aren't complete.
You can see the proper syntax for any doctrine annotation below.
/**
* @ORM\********
*/
So, in your case it should look like the following.
/**
* @ORM\OneToMany(targetEntity="ProductAttributes", mappedBy="product")
*/
You will also want to fix the annotations in the `ProductAttributes` entity.
Problem
I am trying to set up some ManyToOne/OneToMany relationships on objects in my database using Doctrine (2.2.3+) via Symfony2 (2.3.0) and am getting a strange error. Here are the relevant parts of the objects (many attributes to one product): ``` /** * Product * * @ORM\Table(name="product") * @ORM\Entity */ class Product { /** * @var integer * * @ORM\Column(name="id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ protected $id; ... /** * * @OneToMany(targetEntity="ProductAttributes", mappedBy="product") */ protected $product_attributes; public function __construct() { $this->product_attributes = new \Doctrine\Common\Collections\ArrayCollection(); } } /** * ProductAttributes * * @ORM\Table(name="product_attributes") * @ORM\Entity */ class ProductAttributes { /** * @var integer * * @ORM\Column(name="pa_id", type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ protected $pa_id; /** * @var integer * * @ORM\Column(name="product_id", type="integer") */ protected $product_id; ... /** * * @ManyToOne(targetEntity="Product", inversedBy="product_attributes") * @JoinColumn(name="product_id", referencedColumnName="id") */ protected $product; } ``` When I run the ``` php app/console doctrine:generate:entities BundleName ``` command I get the following error: ``` [Doctrine\Common\Annotations\AnnotationException] [Semantical Error] The annotation "@OneToMany" in property LVMount\LVMBundle\Entity\Product::$product_attributes was never imported. Did you maybe forget to add a "use" statement for this annotation? ``` I have looked through the Doctrine docs and don't see any reference to a "use" statement for the ManyToOne/OneToMany pairings. What is going on?
