Upgrade auf Django 1.11.4 ImportError

Question

Ich versuche, Django von 1.10.7 auf 1.11.4 mit Python 2.7.11 zu aktualisieren. Ich habe pip install Django -U ausgeführt und python -c "import django; print django.get_version()" bestätigt, dass Django 1.11.4 installiert ist. Wenn ich dann aber Tests mache, bekomme ich ImportError: No module named notmigrations. Hat jemand einen Rat?

Hier ist der vollständige Stack-Trace:

ImportError: No module named notmigrations 

Answer 1

Es sieht aus wie Sie notmigrations in Ihrer MIGRATION_MODULES Einstellung verwenden Migrationen zu deaktivieren (wie in this post beschrieben). In Django 1.9+ sollten Sie einfach None anstelle eines gefälschten Modulnamens wie 'notmigrations' (release notes) verwenden.

Answer 2

für Django 2.0 I create Einstellungsdatei wie beschrieben here mit Inhalt wie:

from settings import * 

class DisableMigrations(object): 
    def __contains__(self, item): 
     return True 

    def __getitem__(self, item): 
     return None 

MIGRATION_MODULES = DisableMigrations() 

und meine Tests mit Testlauf neu

erstellt Einstellung
