Django get_or_create和ManytoManyField

Question

我以前用的是ForeignKey.

模型

class Phone_request_list(models.Model):
    who = models.IntegerField(null=True)
    whose = models.ForeignKey(User)

视图

def phone_request(request):
    user_id = request.user.id
    uuid = request.GET.get('uuid')
    profile_id = profiles.objects.get(uuid=uuid).user_id
    p,created = Phone_request_list.objects.get_or_create(who=user_id,whose_id=profile_id)
    p.save()

但现在我想将我的模型改为多个领域

class Phone_request_list(models.Model):
    who = models.IntegerField(null=True)
    whose = models.ManyToManyField(User) 

这个时候我怎么能检查whose与who在get_or_create.请帮我.

Answer 1

def phone_request(request):
    user_id = request.user.id
    uuid = request.GET.get('uuid')
    profile_id = profiles.objects.get(uuid=uuid).user_id
    p,created = Photo_request_list.objects.get_or_create(who=user_id)
    p.whose.add(profiles.objects.get(uuid=uuid))
    p.save()

顺便说一句，当您使用ForeignKey时，您不需要最后的p.save（），但是现在您有了M2M
