LookupChoiceFilter doesn't work

[lmbringas]

Maybe this is not de best title idk if LookupChoiceFilter works in other projects but this is my second day debugging and I can't figure out what is happening.

So recently I migrate to django-filter 2.2.0 from version 1. I read that i have to change "The Filter.lookup_expr argument no longer accepts None or a list of expressions. Use the LookupChoiceFilter instead.", so i did it but now i can't filter any more.

I'm using django=2.2.16 and django-rest=3.12.1

I have two models in django

Models
------
class A:
	date = datefield
	pass

Class B:
	a = fk(A)

FilterSet
-----
class BFilterset(FilterSet)
	bla bla
	date = LookupChoiceFilter('a__date', lookup_choices=['exact', 'lte', 'gte'])

when I try to filter by date=, date__gte, date__lte two things happened.

• date= [ this give me invalid the form calling the method from filterset is_valid() ]
• date__gte and date__lte [ the is_valid() method from filterset return true but then doesn't put the date on cleaned_data from DjangoForm that generated.

Please let me known if It doesn't understand some part.
Thank to you that you are reading this. I'll keep investigating this.
