I have UserSerializer and nested UserClientSerializer. I'm trying to update info for logged user. But I receive unique_together validation error.
I have the following models: models.py
class UserClients(models.Model):
user = models.ForeignKey(User, related_name='user_clients')
client = models.ForeignKey(Client, related_name='client_users')
belongs_to = models.BooleanField(default=False)
for_future = models.BooleanField(default=False)
class Meta:
unique_together = ('user', 'client')
Also I have two seralizers. serializers.py
class UserClientsSerializer(serializers.ModelSerializer):
class Meta:
model = UserClients
class UserSerializer(serializers.ModelSerializer):
user_clients = UserClientsSerializer(required=False, allow_null=True, many=True)
class Meta:
model = get_user_model()
exclude = ('password','username', 'date_joined', 'is_superuser')
@transaction.atomic
def create(self, validated_data):
...
@transaction.atomic
def update(self, instance, validated_data):
...
views.py
class CurrentUserDetails(RetrieveUpdateAPIView):
serializer_class = UserSerializer
permission_classes = (IsAuthenticated,)
def get_object(self):
return self.request.user
So, when I trying to update my user data, for example "belongs_to" was False, I want to change it to False. My my JSON data is like this.
{
"user_clients": [
{
"id": 57,
"belongs_to": true,
"for_future": false,
"user": 25,
"client": 3
}
]
}
but i receive validation error like this
{
"user_clients": [
{
"non_field_errors": [
"The fields user, client must make a unique set."
]
}
]
}
Do you have any idea about this problem?
