Django rest adds data to serializer when saving

Question

I want to do the following:

models.py

class MyModel(TimeStampedModel, models.Model):
    name = models.CharField(max_length=100)
    owner = models.ForeignKey(settings.AUTH_USER_MODEL)

serializers.py

class MyModelSerializerCreate(serializers.ModelSerializer):

    class Meta:
        model = MyModel
        fields = (
            'name',
        )

And I would like to add as the owner of the current user in request.user. I am currently adding this to my point of view by first updating request.data with the user and then passing the updated data to my serializer.

    data = request.data
    # Add owner to data
    data["owner"] = request.user.pk
    serializer = self.get_serializer(data=data)
    serializer.is_valid(raise_exception=True)
    self.perform_create(serializer)
    headers = self.get_success_headers(serializer.data)

I would like to do this directly in my serializer, but I can’t find a way to do it right, because it seems like data validation for me. Is that a good idea? Should I stick to this logic in my views or move it to my serializer?

Answer 1

:

self.context['request'].user
get_serializer_context, GenericAPIView:

class GenericAPIView(APIView):
    ....
    def get_serializer_context(self):
        """
        Extra context provided to the serializer class.
        """
        return {
            'request': self.request,
            'format': self.format_kwarg,
            'view': self
        }  

create:

class MyModelSerializerCreate(serializers.ModelSerializer):

    class Meta:
        model = MyModel
        fields = ('name', )

    def create(self, validated_data):
        validated_data['owner'] = self.context['request'].user
        return super(MyModelSerializerCreate, self).create(validated_data)

update delete, user.
