I'm using django rest framework and I have a ListAPIView that I would like
to implement a complex filtering functionality that I'm using Q filters. My
question is how do I generate custom fields for this filtering?
url:
path('', EventListView.as_view(), name='event_list_view'),
serializer:
class EventSerializer(serializers.ModelSerializer):
class Meta:
model = Event
exclude = ('user', )
View:
class EventListView(ListAPIView):
authentication_classes = ()
permission_classes = ()
serializer_class = EventSerializer
filter function:
def filter_events(
user: User, sort_by: int = DISTANCE, privacy_levels: [int] = [
EVERYONE], categories: [Category] = None,
start_date: datetime.datetime = DEFAULT_START_DATE, end_date:
datetime.datetime = DEFAULT_END_DATE,
distance: int = DEFAULT_DISTANCE, current_location: Point = None
, unit: int = None,
clubs: [UniversityClub] = None, universities: [University] =
None,
greeks: [GreekOrganization] = None, groups: [UserGroup] = None,
users_p: [User] = None
):
....
if EVERYONE in privacy_levels:
everyone_q = Q(privacy_level=EVERYONE, university__in=
user_universities, start_time__range=[start_date, end_date])
else:
everyone_q = Q()
if STUDENTS in privacy_levels:
student_q = Q(privacy_level=STUDENTS, start_time__range=[
start_date, end_date])
else:
student_q = Q()
