Symfony 3 - Soucis entités
Bonjour à tous,
Je suis en train de me consacrer à l'apprentissage de Symfony 3 mais je bloque pour un truc tout con.
Je m'explique, j'ai donc un site de développement tout con plutôt très proche de l'exemple donné dans le cours de Symfony 2 sur OCR, j'ai donc :
- Des annonces
- Des catégories
- Des photos
Chaque annonce doit appartenir à une seule et unique catégories, une annonce peut avoir plusieurs photos et une photo est reliée à une seule annonce.
Mon soucis, lorsque je veux créer une nouvelle annonce j'ai droit à ce message :
Citation:
A new entity was found through the relationship 'Adoptez\AnimalsBundle\Entity\Advert#pictures' that was not configured to cascade persist operations for entity: Adoptez\AnimalsBundle\Entity\Pictures@00000000503b70d900000000e3ce266f. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example @ManyToOne(..,cascade={"persist"}). If you cannot find out which entity causes the problem implement 'Adoptez\AnimalsBundle\Entity\Pictures#__toString()' to get a clue.
Voici donc mes entités Adverts et pictures (category fonctionnant bien)
Adverts :
