"detail": "Method \"GET\" not allowed. on calling endpoint in django

I'm using django.rest_framework. I have a get_or_create method for a particular view,

class LocationView(views.APIView):
    def get_or_create(self, request):
        try:
            location = Location.objects.get(country=request.data.get("country"), city=request.data.get("city"))
            Response(location, status=status.HTTP_200_OK)
        except Location.DoesNotExist:
            serializer = LocationSerializer(data=request.data)
            if serializer.is_valid():
                serializer.save()
                return Response(serializer.data, status=status.HTTP_201_CREATED)
            else:
                Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

This is the location Model,

class Location(models.Model):
    country = models.CharField(max_length=255)
    city = models.CharField(max_length=255, unique=True)
    latitude = models.CharField(max_length=255)
    longitude = models.CharField(max_length=255)

    class Meta:
        unique_together = ('country', 'city')

This is my url,

url(r'^location/$', LocationView.as_view(), name='location'),

When I call this endpoint in the following way, http://127.0.0.1:8000/api/v1/bouncer/location/?country=USA&&city=Sunnyvale&&latitude=122.0363&&longitude=37.3688

This is what I get,

{
    "detail": "Method \"GET\" not allowed."
}

What am I missing here.

You need to provide separate methods for get and post. If your get method also creates an instance, then you can just call your current get_or_create inside both get and post methods.

class LocationView(views.APIView):

    def get_or_create(self, request):
        # your current definition here

    def get(self, request):
       return self.get_or_create(request)

    def post(self, request):
       return self.get_or_create(request)

The Method not allowed error is because, it searches for a get() method inside your API class, and it couldn't find a one.
The general format of the API class is as below

class LocationView(views.APIView):
    def get(self, request):
        #do something with 'GET' method
        return Response("some data")

    def post(self, request):
        #do something with 'POST' method
        return Response("some data")


If you want to invoke the get_or_create() method at some point, you can do it as any other methods,

class LocationView(views.APIView):
    def get_or_create(self, request):
        # do some "get or create" stuff
        return "some data"

    def get(self, request):
        if condition:
            self.get_or_create(request)
            # do some stuff
            return Response(" some special data related to get or create")
        return Response("some data")
