Is there a way to declare exclude filters in Meta?

[Bernhard Mäder]

Hey y'all

I'm looking for a way to have negative or excluding filters, which are possible to declare like this:

    not_created__gt = rest_framework_filters.DateFilter(
        field_name="created", exclude=True, lookup_expr='gt')
    not_created__lt = rest_framework_filters.DateFilter(
        field_name="created", exclude=True, lookup_expr='lt')

... but not on Meta. I was hoping I could do something like this:

    class Meta:
        fields = {
            "-created": ["lt", "gt"],
        }

My use case is filtering nullable date values, in which case exclude() is so very valuable.
