About Counting CharField Occurrences
You can count the occurrences of a certain string in all records of a model using annotations like this:
from django.db.models import Count
from places.models import Place
for record in Place.objects.values("city").annotate(
city_count=Count("city"),
).order_by("-city_count"):
print(f"{record['city']}: {record['city_count']}")
