What is your project structure? Do you have app called users? — Rajesh Yogeshwar
– Rajesh Yogeshwar, Commented Nov 28, 2017 at 6:56
Yes, I have an app called users and there is a model called User in models.py. I'm using a abstract user from django user_auth_model. — Vinibr
– Vinibr, Commented Nov 28, 2017 at 18:15
Did you find a solution meanwhile? Stuck with the same problem. — soosap

did you manage to solve this issue ? If not, this is what worked for me:

SHARED_APPS = (
'tenant_schemas',  # mandatory
'apps.user',
'apps.customer',  # must list the app where tenant model resides in
'django.contrib.contenttypes',
# everything below here is optional
'rest_framework',
'django.contrib.auth',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.admin',
'django.contrib.staticfiles',
'django_extensions',
)
TENANT_APPS = (
'apps.user',
'apps.home',
'django.contrib.contenttypes',
# tenant-specific apps
)
INSTALLED_APPS = list(set(SHARED_APPS + TENANT_APPS))

Migration commands:

python manage.py makemigrations customer
python manage.py makemigrations user
python manage.py migrate_schemas --shared

Just as @mjoyshuvo said

'app.user'

should be on both TENANT_APPS and SHARED_APPS due to the fact that some apps in the shared apps try to reference it and it doesn't seems to exists.
