Django dropdown filter queryset with FilterView - django

Question

I want to filter apartments by selecting subcity field in a dropdown in my django app. I'm using django-filters and django-bootstrap-form. But the dropdown does not populate with database querysets. How can I make the dropdown work?
models.py:
from django.contrib.sites.models import Site

# Create your models here.

Your model should be listed in the Meta class.
class yourfilter(django_filters.FilterSet):
class Meta:
model = your_model
