Hello there,
I'm using JMSSerializer to encode a entity that has a relationship with
another one into json, what I'm trying to do is to fetch the parent one,
and get the related one as a set of fields in the json, but what happens is
that I get is 2 empty fields.
I've defined the entities like that:
*Main entity*
> class ftrInvoice {
> /**
> * @ORM\Id
> * @ORM\Column(type="integer")
> * @ORM\GeneratedValue(strategy="AUTO")
> * @Groups({"summary","full"})
> * @Type("integer")
> */
> protected $invoiceId;
> /**
> * @ORM\Column(type="string", length=100)
> * @Groups({"summary","full"})
> * @Type("string")
> */
> protected $invoiceNumber;
> /**
> * @ORM\OneToMany(targetEntity="ftrLineTerm",
> mappedBy="invoiceId",cascade={"persist"})
> * @Groups({"full"})
> */
> protected $lineTerms;
> }
*Related entity*
> /**
> * @ORM\Entity
> * @ORM\Table(name="ftrLineTerm")
> *
> @ORM\Entity(repositoryClass="Afinic\FacturatorBundle\Repository\ftrLineTermRepository")
> * @ExclusionPolicy("None")
> */
> class ftrLineTerm {
> /**
> * @ORM\Id
> * @ORM\Column(type="integer")
> * @ORM\GeneratedValue(strategy="AUTO")
> * @Type("integer")
> */
> protected $lineTermId;
> /**
> * @ORM\ManyToOne(targetEntity="ftrInvoice", inversedBy="lineTerms")
> * @ORM\JoinColumn(name="invoiceId", referencedColumnName="invoiceId")
> */
> protected $invoiceId;
> /**
> * @ORM\Column(type="integer")
> * @Type("integer")
> */
> protected $productId;
> }
When I, from a controller, get a specific invoice and serialize it to JSON
with the following code:
> $invoice =
> $em->getRepository('AfinicFacturatorBundle:ftrInvoice')->findOneByInvoiceId($id);
> $serializer = $this->container->get('serializer');
> $serializer->setGroups(array('full'));
> $result = $serializer->serialize($invoice, 'json');
and return it as a response, what I get is:
{"invoice_id":1,"invoice_number":"WARP-0000001","line_terms":[[],[]]}
There are actually 2 registers in the entity ftrLineTerm for the invoice_id
1, but as you can see, I don't get any of the properties of line_terms
serialized :(
does anybody know what may be happening?
many thanks and sorry for my english!
