django-filter: Using ChoiceFilter with choices dependent on request

Question

I am using django-filter and need to add a ChoiceFilter with choices dependent on the request that I receive. I am reading the docs for ChoiceFilter but it says: This filter matches values in its choices argument. The choices must be explicitly passed when the filter is declared on the FilterSet.

So is there any way to get request-dependent choices in the ChoiceFilter?

I haven't actually written the code but the following is what I want -

class F(FilterSet):
    status = ChoiceFilter(choices=?) #choices depend on request
    class Meta:
        model = User
        fields = ['status']

I've been looking too hard that I found two different ways of doing it! (both by overriding the __init__ method). Code inspired from this question.

class LayoutFilterView(filters.FilterSet):
    supplier = filters.ChoiceFilter(
        label=_('Supplier'), empty_label=_("All Suppliers"),)

    def __init__(self, *args, **kwargs):
        super(LayoutFilterView, self).__init__(*args, **kwargs)

        # First Method
        self.filters['supplier'].extra['choices'] = [
            (supplier.id, supplier.id) for supplier in ourSuppliers(request=self.request)
        ]

        # Second Method
        self.filters['supplier'].extra.update({
            'choices': [(supplier.id, supplier.name) for supplier in ourSuppliers(request=self.request)]
        })

The function ourSuppliers is just to return a QuerySet to be used as choices

def ourSuppliers(request=None):
    if request is None:
        return Supplier.objects.none()

    company = request.user.profile.company
    return Supplier.objects.filter(company=company)
