Django DRF & Updating multiple partial records - django

Question

I'm attempting to update a model that has more fields than what I want to pass to it. I've read the DRF documentation and I'm not finding the right approach. I came across using the UpdateModelMixin but I cannot seem to find a way to implement it successfully.
I've taken a few approaches so far, including using APIView in addition to the methods seen below.
Ultimately, I wish to pass the following to my view and have it update just the "order" field in my model. My model has many fields.
[
{
"id": "1",
"order": "5"
},
{
"id": "2",
"order": "3"
}
]
This is my view:
class WaitlistListGen(generics.ListCreateAPIView):
queryset = Waitlist.objects.all()
serializer_class = WaitlistSerializer
class WaitlistDetailGen(RetrieveUpdateDestroyAPIView):
queryset = Waitlist.objects.all()
serializer_class = WaitlistSerializer
And, this is my serializer:
class WaitlistSerializer(serializers.ModelSerializer):
class Meta:
model = Waitlist
fields = '__all__'

Answer 1

I finally figured it out and believe this is the best approach--I'll take feedback if it's not. I had to create a new view, extend the put method, and iterate over the data. I used the existing WaitlistSerializer:
class WaitlistUpdateGen(generics.UpdateAPIView):
serializer_class = WaitlistSerializer
def put(self, request):
waitlist_data = request.data
for waitlist_item in waitlist_data:
try:
waitlist = Waitlist.objects.get(id=waitlist_item['id'])
except Waitlist.DoesNotExist:
return Response(status=status.HTTP_404_NOT_FOUND)
serializer = self.serializer_class(
waitlist, data=waitlist_item, partial=True)
if serializer.is_valid():
serializer.save()
return Response(status=status.HTTP_200_OK)
