How can I successfully delete the stale content?
Typing yes yields the following:
Creating tables ...
The following content types are stale and need to be deleted:
auth | message
Any objects related to these content types by a foreign key will also be deleted. Are you sure you want to delete these content types? If you're unsure, answer 'no'.
Type 'yes' to continue, or 'no' to cancel: yes
Traceback (most recent call last): ...
raise errorclass, errorvalue
django.db.utils.DatabaseError:
(1146, "Table '<db_name>.auth_group_permissions' doesn't exist")
Process finished with exit code 1
The other thing I tried was:
from django.contrib.contenttypes.models import ContentType
ct = ContentType.objects.get(app_label='auth',model='messages')
And I receive the following:
DoesNotExist: ContentType matching query does not exist.
You can do a
python manage.py dbshell
and check all the tables created by you before.
See if auth_group_permissions exists. If it's not there, I guess you can manually create it and do the process again.
