New description:
When creating a new project, you can sometimes forget to run `manage.py
migrate` before creating the initial superuser (especially if you don't
execute `runserver` before, which display a warning about migrations not
applied). The resulting error make sense, it can't access to auth_user,
since it does not exist yet:
{{{
$ django-admin.py startproject sample
$ cd sample/ && python manage.py createsuperuser
Traceback (most recent call last):
File "manage.py", line 10, in <module>
execute_from_command_line(sys.argv)
[...]
File
"/vagrant/django/django/contrib/auth/management/commands/createsuperuser.py",
line 85, in handle
default_username = get_default_username()
File
"/vagrant/django/django/contrib/auth/management/__init__.py", line 189, in
get_default_username
auth_app.User._default_manager.get(username=default_username)
[...]
File
"/vagrant/django/django/db/backends/sqlite3/base.py", line 323, in execute
return Database.Cursor.execute(self, query, params)
django.db.utils.OperationalError: no such table: auth_user
}}}
... but with a little try/except, it could be nicer and
give a more meaningful information:
{{{
$ python manage.py createsuperuser
CommandError: You must execute `manage.py migrate` once
before creating a super user
}}}
I have a patch ready (as I said, it just a try/except, see
attachment) but, if accepted, it would need unit tests to be complete.
