Django sur nueva instalación -> error: comando desconocido 'schemamigration'

Question

cuento

corro ./manage.py schemamigration junk_app --initial en un proyecto Django completamente nuevo justo después de la instalación recién Sur (http://south.aeracode.org/), y me sale el siguiente error:

Unknown command: 'schemamigration' 
Type 'manage.py help' for usage. 

EDIT: tengo la versión 0.7 (sur/init.py tiene versión =" 0.07")

Answer 1

Probablemente estés usando alguna versión antigua del Sur, 0.6.xo incluso 0.5.x. Si escribe esa "./manage.py help", debería ver startmigration (iirc) en la lista de comandos disponibles.

Answer 2

En lugar de usar el paquete Ubuntu, use easy_install o pip para instalar South. Esto asegurará que tengas la versión más reciente.

Answer 3

Probablemente no haya agregado 'sur' en la lista de INSTALLED_APPS de su archivo settings.py.

Aquí es una cita de http://south.aeracode.org/docs/installation.html#installation-configure

Now you’ve installed South system-wide, you’ll need to configure Django to use it. Doing so is simple; just edit your settings.py and add 'south' to the end of INSTALLED_APPS.

If Django doesn’t seem to pick this up, check that you’re not overriding INSTALLED_APPS elsewhere, and that you can run import south from inside ./manage.py shell with no errors.

Once South is added in, you’ll need to run ./manage.py syncdb to make the South migration-tracking tables (South doesn’t use migrations for its own models, for various reasons).

Answer 4

cheque, que settings.py archivo que utiliza:

./manage.py shell 
import settings 
settings.__file__ 

que puede ver en manage.py, que los ajustes del archivo de Django uso por defaul:

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "app.settings") 

o puede usar:

$./manage.py schemamigration junk_app --settings=settings --initial 

en lugar de:

$./manage.py schemamigration junk_app --initial 

Answer 5

Si usted tiene su configuración en una carpeta de configuración, asegúrese de usar un . y no / en la ruta. Ejemplo: ./manage.py schemamigration secretballot --initial --settings=settings.jacob

Answer 6

Creo que este problema puede ser muy elusivo. Pasé un tiempo considerable y luego me di cuenta de que estaba anulando INSTALLED_APPS para algunas pruebas. Doh! Entonces esta es la clave. Asegúrese de agregar south al final de su INSTALLED_APPS y si lo reemplaza, verifique también.
