@peppelinux could you give a bit more information about your system.
It works for myself on my machine with the following:

  • Django (1.11) also on (1.11.2)
  • Django-q (0.8.0)

I run macOS Sierra (v10.12.5)

Sorry, first drink coffee then read stuff... I tried django 1.10.7 with djang-q but din't get any errors.
Unfortunately I can't check on Debian or Python 3.5.

With python2 it doesn't exist, I had this exception with python 3.5 but I should do some other accurate tests

Hi,

I have the same issue.
If we investigate in the file monitor.py, we see in line 204 that the object exec_time["time_taken" has type "decimal.Decimal".

But the method "total_seconds()" it's a timedelta method.
https://docs.python.org/2/library/datetime.html#datetime.timedelta.total_seconds

            exec_time = last_tasks.aggregate(
                time_taken=Sum(F("stopped") - F("started"))
            )

            exec_time = exec_time["time_taken"].total_seconds() / tasks_per_day```

I have the same issue @ version 1.3.9 on Redis 5.0.14, MariaDB 10.3.29 and Python 3.9.1

My temp solution is delete .total_seconds().

Thank You~
