How to enable "PUT to create" with Django Rest Framework

drf_viewsets.py

from rest_framework import viewsets
from django.http import Http404

class MyViewSet(viewsets.ModelViewSet):
    serializer_class = MySerializer
    # ...

    def update(self, request, *args, **kwargs):
        partial = kwargs.get('partial', False)
        try:
            return super(MyViewSet, self).update(request, *args, **kwargs)
        except Http404:
            if partial:
                raise

            # Allow PUT to create
            return super(MyViewSet, self).create(request, *args, **kwargs)

    def perform_create(self, serializer):
        save_kwargs = {
            # You may add other implicit fields here, such as client app version 
            'owner': self.request.user,
        }

        # Allow PUT to create: if this is a PUT, we'll get the primary key in
        # the URL kwargs.
        #
        # If you're using some other url-kwargs or are indexing models by some
        # other key, then adapt this logic to match.
        if 'pk' in self.kwargs:
            save_kwargs['pk'] = self.kwargs['pk']

        serializer.save(**save_kwargs)
