Can't reproduce this. Works fine on Python 3.7.2 with Django 2.1.5.

I'm running in to this also on python 3.6.4 and Django 1.11.18.

[theunraveler]

Looks to me like a circular import:

File "{ENV}/lib/python3.6/site-packages/django_q/cluster.py", line 24, in <module>
    from django_q import tasks
File "{ENV}/lib/python3.6/site-packages/django_q/tasks.py", line 12, in <module>
    from django_q.cluster import worker, monitor

[Koed00]

@viperfx could it have been that you were running Django 1.11?

[theunraveler]

Is this a known issue on Django 1.11?

[codeSamuraii]

I'm running into this issue as well...
Tried with Python 3.6.8 and 3.7.2.

Django 2.1.7 - Django-q 1.0.1

[yannbu]

+1

Django-q 1.0.1
Django 2.1.4
Python 3.6.0

Happens when directly initiating a cluster in my code (not using the management command)

[codeSamuraii]

I have a temporary fix.

In django_q/tasks.py, replace the line :

from django_q.cluster import worker, monitor

by

from django_q.cluster import *

The manage.py qcluster command then works for me.

Submitted a pull request with the modification (#343).

EDIT: See PR #356 for a better solution.

[telenieko]

Same with Django 2.1.7, django-q 1.0.1, python 3.6.8
Same with Django 2.1.5, django-q 1.0.1, python 3.6.8
Same with Django 2.1.0, django-q 1.0.1, python 3.6.8
Same with Django 2.1.0, django-q 1.0.0, python 3.6.8

[sato-s]

I have same issue.

Python 3.7.2,Django 2.1.5,django-q 1.0.1

[viperfx]

@Koed00 I think it's worth reviewing this?

Seems to be a long list of people having this issue

[lamby]

Can reproduce here:

• django.VERSION == (2, 2, 0, 'final', 0)
• django-q version 1.0.1
• sys.version is 3.7.2+ (default, Feb 2 2019, 14:31:48) \n[GCC 8.2.0]

[lamby]

Alternative PR created at #356

[grigory51]

Put your django_q app in INSTALLED_APPS after django.contrib.admin

[lamby]

I'm not using django.contrib.admin and am seeing this.

[joantune]

Guys! - had the same issue with Python 3.7.0 - and Django 2.1.7

Solved it - the issue was that I didn't have django.contrib.admin in the INSTALLED_APPS - just make sure it's there and before django_q as @grigory51 pointed out
Cheers!

[lamby]

Perhaps, but that's not the real, ongoing solution. I mean, django-q should not require using the Django admin, at the very least, and the order of INSTALLED_APPS should not make any difference.
