Django REST: CREATE function is not calling inside serialize class

Question

The problem is create function is not calling and simply returning validation Boolean value whether its true or false. Please note: Validation part is working fine.

Code as follows:

Views.py

class TestAPI(APIView):
    serializer_request = TestAPISerializer

    def post(self,request):     
        obj = self.serializer_request(data=request.data)
        print obj.is_valid()
        if obj.is_valid():
            obj.save()
            return Response(status=status.HTTP_200_OK)
        else:
            return Response(request_for_demo_ser.errors, status=status.HTTP_400_BAD_REQUEST)

Serializers.py

class TestAPISerializer(serializers.ModelSerializer):
    class Meta:
        model = TestDemo
        fields = ('name')

    # THIS FUNCTION IS NOT AT ALL CALLING. 
    def create(self, validated_data):
        name = validated_data['name'] 
        return TestDemo.objects.create(name=name)

You forgot save.

obj = self.serializer_request(data=request.data)
print obj.is_valid()
if obj.is_valid():        
    obj.save()  # add this line
    # Change code to 201
    return Response(status=status.HTTP_201_CREATED)
    # return Response(status=status.HTTP_200_OK)

mrvol Over a year ago

isn't function not calling now?

Great !! sorry for the delay. I was used save method before, at that time its was not worked. but now, it is worked properly !! One quick question, why we need save method explicitly in views.py? can't we save in serializer.py or models.py ?

We can decide about save in view only. If data valid and user has permission to save, we'll call save method, in other case we don't save and send message to user. This pattern named MVC. You can read more in wiki en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller P.S.: Sorry for my English
