django signale sur l'utilisateur créer

J'ai connecté la création d'utilisateur avec la fonction create_user_profile, le problème vient quand je crée l'utilisateur, il semble que les fonctions connectées sont appelées deux fois et UserProfile essaye d'être créé deux fois, une erreurdjango signale sur l'utilisateur créer

S'il vous plaît formater votre code correctement. – cfedermann

Utilisez le raisonnement dispatch_uid pour donner le signal d'un identifiant unique.

post_save.connect(create_user_profile, sender=User, dispatch_uid="create_user_profile")

Pour plus d'informations, voir le django docs.

Ceci sert à empêcher les signaux d'être * connectés * plusieurs fois; il sera encore * feu * plusieurs fois si l'action * se produit * plusieurs fois. –

Mais les profils ne sont créés que si ['created'] (https://docs.djangoproject.com/en/dev/ref/signals/#django.db.models.signals.post_save) est' True'. 'created' sera' False' pour les sauvegardes suivantes. – Alasdair

Vous pouvez éviter le problème en ajoutant un contrôle supplémentaire de la santé mentale à votre méthode:

def create_user_profile(sender, instance, created, **kwargs): 
    if created and not UserProfile.objects.exists(user=instance): 
     UserProfile.objects.create(user=instance) 
     PageSettings.objects.create(user=instance)

Bien que je pense que ce contrôle de santé fonctionne, je pense qu'il est préférable de traiter le problème sous-jacent (que la fonction de récepteur 'create_user_profile' était enregistrée deux fois) en spécifiant' dispatch_uid'. – Alasdair

Bien sûr; il est toujours préférable de réparer la racine du mal :) – cfedermann
