filter_class does not respect filter_fields, Filter.fields

[gthieleb]

endpoints.py:

@register
class StageEndpoint(Endpoint):

    model = Stage
    read_only = True

    filter_class = StageFilter
    filter_fields = ('middleware', 'tshirt_size', 'service_level')

filtersets.py:

class MiddlewareSpecFilter(FilterSet):
    """ this is the base filter
        based on the intermediate table middlewarespec
        to filter specific attributes that are related to middlewarespecification """
    middleware = filters.CharFilter(label='Middleware',
            name='middlewarespecification__middleware__name',
            distinct=True)
    stage = filters.CharFilter(label='Stage',
            name='middlewarespecification__stage__stage',
            distinct=True)
    service_level = filters.CharFilter(label='Service Level',
            name='middlewarespecification__service_level',
            distinct=True)
    tshirt_size = filters.CharFilter(label='Tshirt Size',
            name='middlewarespecification__tshirt_size',
            distinct=True)

class StageFilter(MiddlewareSpecFilter):

    class Meta:
        model = Stage
        fields = ('middleware',
                  'tshirt_size',
                  'service_level')

The expected behavior is that filtering is possible for middleware, tshirt_size, service_level. The result is that filtering is also available for stage.

Same behavior with traditional viewset / filterset. I opened issue carltongibson/django-filter#905

Yes, this is not an issue with drf-schema-adapter, as you've noted, this is an issue with django-filter and it might even be an intended feature.

I'm closing this issue since it's not related to this library

[nanuxbe]

Even if this is an upstream issue, there might be something drf-schema-adapter can do about it. Re-opening the issue
