Answer 1

After some studies, I've found this simple solution

class ProductFilter(django_filters.FilterSet):
    class Meta:
        model = Product
        fields = [ 'shortname', 'fullname', 'description', 'product_type',   ]

    def __init__(self, *args, **kwargs):
        super(ProductFilter, self).__init__(*args, **kwargs)
        # at sturtup user doen't push Submit button, and QueryDict (in data) is empty
        if self.data == {}:
            self.queryset = self.queryset.none()

I think, this solution is stable. How do you think?
