so I have a User and schools model which are related as an Owens(ManyToMany), student, and staff, if an owner registers and creates a school, I would like to perform a partial update to the Owens field of the request.user from having a null/blank or previously created schools to adding the newly created school
user model
class User(AbstractBaseUser, PermissionsMixin):
class SEX(models.TextChoices):
...
class TYPES(models.TextChoices):
...
...
owens = models.ManyToManyField(School, verbose_name=_(
"School_owner"), related_name='Schoolowner', blank=True)
serializers.py
class SchoolSerializerBase(serializers.ModelSerializer):
...
class Meta:
model = School
fields = ...
def validate(self, attrs):
...
return attrs
def create(self, validated_data):
instance = School.objects.create(
...
)
instance.save()
return instance
and i have a simple view for it
class CreateSchoolView(generics.CreateAPIView):
queryset = School.objects.all()
permission_classes = [IsSchoolOwner, ]
serializer_class = SchoolSerializerBase
My question: how do I update the request.user.ownes field and add the school instance to it??
CodePudding user response：
You can obtain that result by overriding .create() in your serializer
In your serializer
def create(self, validated_data):
instance = super().create(validated_data) # this is the school
# you then create the entry for your User School
# example
user = self.context['request'].user
user.owens.add(instance)
return instance
