How to add an initial/default value using Django Filters?

Question

How can I add an initial/default value when using Django Filters?

For example, something like this initial=False

class UserFilter(django_filters.FilterSet):
    archive = django_filters.BooleanFilter(initial=False)

    class Meta:
         model = User
         fields = ['archive']

I've tired to override the __init__ but this does not appear to work.

For DRF you can try override __init__:

def __init__(self, *args, **kwargs):
    kwargs['data']._mutable = True
    if 'archive' not in kwargs['data']:
        kwargs['data']['archive'] = False
    kwargs['data']._mutable = False
    super(UserFilter, self).__init__(*args, **kwargs)

But you should read django-filter.readthedocs.io...using-initial-values-as-defaults
