Swagger Schema Generation generates the wrong fields for gets

[efagerberg]

Full disclosure I am seeing this using a filterset from djangorestframework-filters

I noticed when setting up a filter with all lookup fields on a viewset that all the filters end up in the get method. These filters are most likely useless for gets and should not be included as parameters.

class Person(filters.FilterSet):

    class Meta:
        model = Node
        fields = {
            'id': '__all__',
            'name': '__all__',
        }

A serializer like this

class PersonSerializer(serializers.ModelSerializer):
    class Meta:
        model = Person
        fields = ('id', 'name')

and finally a viewset like this

class PersonViewSet(viewsets.ReadOnlyModelViewSet):

    queryset = Person.objects.all()
    serializer_class = PersonSerializer
    filter_class = PersonFilter

If I register this to my urls I would get a route for a list view and a get similar to this api/person/ and api/person/{id}

And if I go to say swagger and check the get Person API out I would notice that I have filter options for the get like this screenshot.

The issue here is, get requires an id and you usually do not need more than that, so these filter options are superfluous.
