Still not. Assertions are disabled when running with the -o flag, so
you'd better only use them for debugging purpose only (which is the
intended use).

Also and FWIW, the call to objects.all is useless (and costly -
cloning a queryset is not free) if you apply a filter on the resulting
queryset. idem for the second call to filter, which is functionally
equivalent to passing both criterions in the same call.

If you can't use a QuerySet.get() method, the proper code would look
like:

res = UserAccount.objects.filter(
user_id=check.id,
video_id=pid
).order_by('-datestamp',)

try:
checkview = res[0]
except IndexError:
