Pass request context to serializer from Viewset in Django Rest Framework

GenericViewSet has the get_serializer_context method which will let you update context:

class myModelViewSet(ModelViewSet):
    queryset = myModel.objects.all()
    permission_classes = [DjangoModelPermissions]
    serializer_class = myModelSerializer

    def get_serializer_context(self):
        context = super(myModelViewSet, self).get_serializer_context()
        context.update({"request": self.request})
        return context

just use get_serializer() in your viewsets

def get_serializer(self, *args, **kwargs):
    """
    Return the serializer instance that should be used for validating and
    deserializing input, and for serializing output.
    """
    serializer_class = self.get_serializer_class()
    kwargs['context'] = self.get_serializer_context()
    return serializer_class(*args, **kwargs)

For Function based views you can pass request or user as follow:

serializer = ProductSerializer(context = {'request':request},data=request.data)

Your Serializer may look like:

class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model    = Product
        fields   = ['id']

    def create(self, validated_data):
        user =  self.context['request'].user
        print("User is")
        print(user)

Feel free to inform if there is any better way to do this.
