问题:
I apologize in advance if this has been asked before.
I have successfully setup FOSUserBundle.
I am trying to setup "http://symfony.com/doc/current/book/doctrine.html" the product example from that link out of the documentation.
What I would like to do is set it up so a specific user adds a product the User Id of the FOSUser that user is associated with that product.
I have two bundles in the Acme folder
Acme/UserBundle -> the FOSUser Setup
and
Acme/MainBundle -> where I am setting up products.
I've gone over the relationship documents a few time and I am not quite clear on them in Symfony2.
I think it is a OneToMany relationship in the User Entity based on a "user_id" in the Products table but i'm not a 100% sure how to do it.
Does anyone know a tutorial or even a basic idea on if I am going in the right direction on this? Thanks very much and I will obviously publish the successful results Once I get there.

You just have to add a relation between your user and your product. So your Product entity should be like this :
src/Acme/MainBundle/Entity/Product.php
namespace Acme\MainBundle\Entity; use Doctrine\ORM\Mapping as ORM; /** * @ORM\Entity * @ORM\Table(name="product") */ class Product { /** * @ORM\Column(type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ protected $id; /** * @ORM\Column(type="string", length=100) */ protected $name; /** * @ORM\Column(type="decimal", scale=2) */ protected $price; /** * @ORM\Column(type="text") */ protected $description; /** * @ORM\ManyToOne(targetEntity="Acme\UserBundle\Entity\User", inversedBy="products") * @ORM\JoinColumn(name="user_id", nullable=false) */ protected $user; }
And your user entity
src/Acme/UserBundle/Entity/User.php
namespace Acme\UserBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Acme\MainBundle\Entity\Product; /** * @ORM\Entity * @ORM\Table(name="user") */ class User { /**- * User properties... */ /** * @ORM\OneToMany(targetEntity="Acme\MainBundle\Entity\Product", mappedBy="user", cascade={"remove"}) */ protected $products; /** * Constructor */ public function __construct() { $this->products = new \Doctrine\Common\Collections\ArrayCollection(); } /** * Add product * * @param Product $product * @return Branch */ public function addProduct(Product $product) { $this->products[] = $product; return $this; } /** * Remove product * * @param Product $products */ public function removeProduct(Product $product) { $this->products->removeElement($product); } /** * Get products * * @return \Doctrine\Common\Collections\Collection */ public function getProducts() { return $this->products; } }
Everything is explain in the doctrine documentation

The following works perfectly for me in Symfony 2.3 I got it from Reading the docs and going the knpuniversities episode 3 on Symfony2 I hope it helps someone.
The Entity
use Doctrine\ORM\Mapping as ORM; use Acme\UserBundle\Entity\User; /** * @ORM\Entity * @ORM\Table(name="products") */ class Products { /** * @ORM\Column(type="integer") * @ORM\Id * @ORM\GeneratedValue(strategy="AUTO") */ protected $id; /** * @ORM\Column(type="string", length=100) */ protected $name; /** * @ORM\Column(type="decimal", scale=2) */ protected $price; /** * @ORM\Column(type="text") */ protected $description; /** * Get id * * @return integer */ public function getId() { return $this->id; } /** * Set name * * @param string $name * @return Products */ public function setName($name) { $this->name = $name; return $this; } /** * Get name * * @return string */ public function getName() { return $this->name; } /** * Set price * * @param float $price * @return Products */ public function setPrice($price) { $this->price = $price; return $this; } /** * Get price * * @return float */ public function getPrice() { return $this->price; } /** * Set description * * @param string $description * @return Products */ public function setDescription($description) { $this->description = $description; return $this; } /** * Get description * * @return string */ public function getDescription() { return $this->description; } /** * @ORM\ManyToOne(targetEntity="Acme\UserBundle\Entity\User", cascade={"remove"}) * @ORM\JoinColumn(onDelete="CASCADE") */ private $owner; public function getOwner() { return $this->owner; } public function setOwner(User $owner) { $this->owner = $owner; } }
and in the Controller
/** * Creates a new Products entity. * */ public function createAction(Request $request) { $entity = new Products(); $form = $this->createCreateForm($entity); $form->handleRequest($request); if ($form->isValid()) { $em = $this->getDoctrine()->getManager(); // Associate User Entity To Product $user = $this->container->get('security.context')->getToken()->getUser(); $entity->setOwner($user); $em->persist($entity); $em->flush(); return $this->redirect($this->generateUrl('products_show', array('id' => $entity->getId()))); } return $this->render('AcmeMainBundle:Products:new.html.twig', array( 'entity' => $entity, 'form' => $form->createView(), )); }
