View chunking pattern
# General pattern for a data "chunking" process to prevent a server from hitting memory limits
# when calling .update() or .delete() on large amounts of data. In this example, we enter an
# infinite loop, then keep deleting 1000 records at a time until the records are exhausted,
# then exit the loop. You can't call .update() or .delete() after taking a slice, hence the need
# for two queries rather than one.
t = Territory.objects.get(name="some-territory")
while True:
loc_ids = Location.objects.filter(territory=t)[:1000].values_list("id", flat=True)
