Save query string data using rest framework in Django

Question

I need to save to a database the query string data coming from a GET request using Django Rest framework.

Something like this:

URL: "http://127.0.0.1:8000/snippets/snippets/?longitude=123123&latitude=456456"

class SnippetList(generics.ListCreateAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer
    #code here for saving the query string data to database, in this case save: 
    #{
    #"longitude":123123,
    #"latitude":456456
    #}

It's just like saving the params data like it were a POST request.

You should not do that: A GET request should not have side-effects per specs of the HTTP protocol. — willeM_ Van Onsem

I need to save to a database the query string data coming from a GET request using Django Rest framework.

This is against the specifications of the HTTP protocol. Indeed, a GET request should only be used to retrieve data, not update data. For that a POST, PUT, PATCH or DELETE request should be used. The querystring is normally used to filter, not to store data.

If you really want to do this, you can override the .get(…) handler and

# Warning: against the HTTP protocol specifications!
class SnippetCreateView(generics.CreateAPIView):
    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer
    # {
    # "longitude":123123,
    # "latitude":456456
    # }
    def get(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.query_params)
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        headers = self.get_success_headers(serializer.data)
        return Response(
            serializer.data, status=status.HTTP_201_CREATED, headers=headers
        )

But this is really not a good idea.

For some reason the App I am using: gpslogger.app, send a get request to send the gps data: myserver.com/log?lat=%LAT&long=%LON... I need to save that data to a database. What do you think of this? By the way your solution worked good, thanks!
