My class:
class InvoicePeriodViewSet(viewsets.ModelViewSet):
permission_classes = (
permissions.AllowAny,
)
queryset = models.InvoicePeriod.objects.all()
serializer_class = serializers.InvoicePeriodSerializer
filter_backends = (django_filters.rest_framework.DjangoFilterBackend,)
filterset_fields = ('days_interval', )
it's not working at all. I searched in other stack overflow questions and they didn't help me (here, here, here and here).
I have 'django-filter' (django-filter==1.0.4) added to my apps, my django version is (Django==1.11.1) and rest (djangorestframework==3.8.2)
I really don't want to add a filter_class. I have other view with filterclass and it's working but I don't want to make so many filterclasses. It would be perfect that the filterset_fields feature worked. If not I will have to create the filter_class by a function so I won't have to create 30+ of them.

The DjangoFilterBackend class is used to filter the queryset based on a specified set of fields. This backend class automatically creates a FilterSet (django_filters. rest_framework. FilterSet) class for the given fields.
The simplest way to filter the queryset of any view that subclasses GenericAPIView is to override the . get_queryset() method. Overriding this method allows you to customize the queryset returned by the view in a number of different ways.
Set search fields using the query parameter The Django REST framework provides search functionality out of the box. Search can be accomplished by following three steps: Setting search_fields in the class. Setting filter_backends in the class.
Arguments: queryset - The queryset used for model instance lookups when validating the field input. Relationships must either set a queryset explicitly, or set read_only=True . many - If applied to a to-many relationship, you should set this argument to True .
Well, finally I found the problem thanks to validname answer. He suggested to use "filter_fields" I went into django-filter documentation and found that in new version (1.1.0) filter_fields is renamed to filterset_fields, so as I was using django-filter 1.0.4 the filterset_fields didn't exists.
