Ich habe Django 1.6.6 auf Produktion und vor kurzem auf 1.9.7 auf Staging (dev Server) aktualisiert. Dieses Update wurde auf dem Server durchgeführt und ich befolgte die hier beschriebenen Schritte Upgrading from South.Upgrade von Django 1.6 auf 1.9: Python manage.py migrieren Fehler
Ich habe festgestellt, dass sich die Struktur der Migrationsdateien geändert hat und sie keine create
-Anweisung mehr enthalten. Dies verursacht Probleme, weil, wenn ich diesen neuen Code aus meinem GitHub Repo ziehen und laufen python manage.py makemigrations
oder python manage.py migrate
, heißt es:
django.db.utils.OperationalError: no such table: appname_modelname
Die Zurückverfolgungspunkte auf meine urls.py, weil ich das Modell in einem queryset bin Referenzierung :
queryset=list(chain(models.modelname.objects.filter(booleanField=True).order_by(object), models.aDifferentModel.objects.all())),
Vor dem 1.9 Upgrade erstellt syncdb
die Tabellen für mich, aber das ist nicht der Fall mit migrate
. Ich habe auch versucht python manage.py migrate --run-syncdb
, aber das gibt den gleichen Fehler.
Wenn ich jedoch die SQLite-Datenbank von meinen Produktions- oder Staging-Umgebungen auf meine lokale Maschine kopiere und den Befehl ausführe, funktioniert dies (weil die Tabelle bereits in der Datenbank vorhanden ist).
Muss ich diese Tabellen manuell erstellen (obwohl ich nicht davon ausgehe) oder mache ich etwas falsch?
Bearbeiten: Code-Schnipsel und Tracebacks hinzugefügt. Tut mir leid, dass ich das anfangs nicht gemacht habe.
