Django: Application labels aren't unique

Question

I have been working on the issue of duplicate labels in Django and from this answer I have added the following files to my "jobs" project folder:

jobs/apps.py

# jobs/apps.py

from django.apps import AppConfig

class JobsConfig(AppConfig):
    name = 'jobs'
    verbose_name = "jobs2"

jobs/init.py

# jobs/__init__.py

default_app_config = 'jobs.apps.JobsConfig'

This hasn't really helped much and I still get the error when trying syncdb:

"duplicates: %s" % app_config.label)
django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: jobs

Also, changing from "name = 'jobs'" to "name = 'jobs2'" just gives me the error:

ImportError: No module named jobs2

Try to replace `verbose_name` with `label`: `label = "jobs2"`. I had the same problem and it works for me. — coldmind, Oct 10 '14 at 11:57
Also clean all `.*pyc`, it often does not works without this. — coldmind, Oct 10 '14 at 12:02
Thanks, I removed all .pyc files, renamed verbose_name with label then ran a syncdb, but this still gave the error.. — Jon, Oct 10 '14 at 12:25
In `name=jobs`, is `jobs` a full path to that module (from sources root) ? — coldmind, Oct 10 '14 at 13:05

You have a mix of old-style (south: 0002_auto_del...) and new-style (django: 0001_initial) migrations in your jobs app. Easiest fix would be to delete all numbered migrations rm jobs/migrations/0???_*.py* and recreate migrations by running manage.py makemigrations

That worked for me @ryuusenshi :). I had the same issue, and it solved my day ;). Thanks – Vladir Parrado Cruz Oct 27 '15 at 15:01
no problem :) I submitted a ticket to code.djangoproject.com to make the error message more descriptive and it should be fixed in 1.8.6. – ryuusenshi Oct 27 '15 at 20:40
