python - Django orm filter is an element of dict -

-

i'm trying set dict of filters orm queryset. here dict:

section = self.kwargs['section'] # hot or new or trending threshold = {'hot': 'post_upvotes > 50', 'trending': 'post_upvotes__range=(20,50)', 'new': 'post_upvotes < 20'} return post.objects.filter(threshold[section])

but doesn't work.

how can achieve ?

try this:

from django.db.models import q  threshold = {     'hot': q(post_upvotes__gt=50),     'trending': q(post_upvotes__range=(20,50)),     'new': q(post_upvotes__lt=20) }  return post.objects.filter(threshold[section])
