Enhancement: A easier way to filter with exclude=True

[hongfanmeng]

class ExampleFilter(FilterSet):
    id__not__in = NumberInFilter(field_name='id', lookup_expr='in', exclude=True)

is it possible to auto generate [field_name]__not__[lookup] filter ?

[hongfanmeng]

To be precise, I want to automatically generate suffix of all lookup with or without exclude

I really want this too, #978 and see this discussion about it, #1484

Hello, I have recently started used django-fliters and also stumbled upon this.

I have written some minimal mixins which enable this behavior on django-filters (tested on DRF, not sure if compatible at all with forms). You can find them here https://github.com/WhiteSage/django-filter-autotools .

I invested sometime to analysed and do a extension to have automagically exclude on any lookup. Posted the snnipets here
