Serializer doesn't save data into DB, but response is 200
问题
I need to take data by using keys from different models, and then put them together and save into another model.
views.py:
def create_order(self, request):instance = self.get_object()serializer = CreateOrderSerializer(instance, data=request.data)serializer.is_valid(raise_exception=True)serializer.save()print(serializer.data)return Response(serializer.data)
serializers.py:
class CreateOrderSerializer(serializers.ModelSerializer):user_name = serializers.ReadOnlyField(source="author.username", required=False, allow_null=True)book = serializers.ReadOnlyField(source="book_name", required=False, allow_null=True)class Meta:model = orderfields = ("id", "user_name", "book")
I can access and operate with data which I need, and I get a 200 response when making a POST request, but data doesn't save. By the way, when I create an "order" in the admin menu everything works fine, thus I assume something is going wrong in either my view or serializer.

serializer.py
class CreateOrderSerializer(serializers.ModelSerializer):user_name = serializers.CharField(source="author.username", required=False, allow_null=True)book = serializers.CharField(source="book_name", required=False, allow_null=True)class Meta:model = orderfields = ("id", "user_name", "book")
views.py
def create_order(self, request):instance = self.get_object()serializer = CreateOrderSerializer(instance, data=request.data)serializer.is_valid(raise_exception=True)user_id = request.userorder.objects.create(user=user_id,book=instance,)return Response(serializer.data)

Finally i fixed this.
serializer.py
class CreateOrderSerializer(serializers.ModelSerializer):user_name = serializers.CharField(source="author.username", required=False, allow_null=True)book = serializers.CharField(source="book_name", required=False, allow_null=True)class Meta:model = orderfields = ("id", "user_name", "book")
views.py
def create_order(self, request):instance = self.get_object()serializer = CreateOrderSerializer(instance, data=request.data)serializer.is_valid(raise_exception=True)user_id = request.userorder.objects.create(user=user_id,book=instance,)return Response(serializer.data)
