Sonata Admin Bundle One-to-Many relationship not saving foreign ID

Question

I have a problem with the SonataAdminBunle in combination with symfony 2.2. I have a Project entity and a ProjectImage entity and specified a One-to-Many relationship betwee

Answer 1

One way that I solved the was to manually set all inverse-side associations through a custom Sonata model manager.

getEntityManager($object);
            $entityManager->persist($object);
            $entityManager->flush();
            $this->persistAssociations($object);
        } catch (\PDOException $e) {
            throw new ModelManagerException('', 0, $e);
        }
    }

    /**
     * {@inheritdoc}
     */
    public function update($object)
    {       
        try {
            $entityManager = $this->getEntityManager($object);
            $entityManager->persist($object);
            $entityManager->flush();
            $this->persistAssociations($object);
        } catch (\PDOException $e) {
            throw new ModelManagerException('', 0, $e);
        }
    }

    /**
     * Persist owning side associations
     */
    public function persistAssociations($object)
    {       
        $associations = $this
            ->getMetadata(get_class($object))
            ->getAssociationMappings();

        if ($associations) {
            $entityManager = $this->getEntityManager($object);

            foreach ($associations as $field => $mapping) {
                if ($mapping['isOwningSide'] == false) {
                    if ($owningObjects = $object->{'get' . ucfirst($mapping['fieldName'])}()) {
                        foreach ($owningObjects as $owningObject) {
                            $owningObject->{'set' . ucfirst($mapping['mappedBy']) }($object);
                            $entityManager->persist($owningObject);
                        }
                        $entityManager->flush();
                    }
                }
            }
        }
    }
}

Be sure to define this as a new service in your services.yml file:

services:
    sample.model.manager:
        class: Sample\AdminBundle\Model\ModelManager
        arguments: [@doctrine]


    sample.admin.business:
        class: Sample\AdminBundle\Admin\BusinessAdmin
        tags:
            - { name: sonata.admin, manager_type: orm, group: "Venues", label: "Venue" }
        arguments: [~, Sample\AppBundle\Entity\Business, ~]
        calls:
            - [ setContainer, [@service_container]]
            - [ setModelManager, [@sample.model.manager]]
