Intégration de clé étrangère lors d'un make:fixture:load

**Goosh** · 03/02/2022, 22h45

Bonjour ou bonsoir,

Je n'arrive pas à créer ma fixture Manuscript qui prend en référence un User afin d'ajouter l'id de ce dernier à author_id (contenu dans manuscrit)... J'ai cette 'belle' erreur :

Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`testbook2`.`manuscript`, CONSTRAINT `FK_5AF919CD69CCBE9A` FOREIGN KEY (`author_id_id`) REFERENCES `user` (`id`))

J'ai parcouru divers forum qui disent qu'il faut utiliser cascade:['persist'] (Je suis en php 8, c'est cette syntaxe qui est utilisée). J'ai donc essayer cela des deux côtés de mon entité, mais ça ne fonctionne pas... De plus, je n'arrive pas bien à déterminer qui est le parent de qui dans cette histoire. Je suis perdu, je l'avoue... Si l'un ou l'une d'entre vous pouvait m'éclairer je lui en serai reconnaissant. Merci d'avance !!

Lors de la création de ma fixture il ne pouvait pas détruire l'ancien user, car celui-ci était lié à la table manuscript... J'ai donc effacé les manuscrits mais y a t'il une solution plus propre si jamais une manipulation similaire devait être faite ?
Bon en tous cas ça marche c'est l'essentiel...
