我創建的應用程序Notification
數據遷移,在這裏我使用的模型,Manager
的參考,從應用accounts
的Django 1.7遷移無法找到應用程序
Manager = apps.get_model("accounts", "Manager")
它拋出錯誤:
self.code(from_state.render(), schema_editor)
File "/home/notifications/migrations/0004_auto_20150720_0127.py", line 12, in set_notification_setttings
Manager = apps.get_model("accounts", "Manager")
File "/home/local/lib/python2.7/site-packages/django/apps/registry.py", line 202, in get_model
return self.get_app_config(app_label).get_model(model_name.lower())
File "/home/local/lib/python2.7/site-packages/django/apps/registry.py", line 150, in get_app_config
raise LookupError("No installed app with label '%s'." % app_label)
LookupError: No installed app with label 'accounts'
雖然從殼我想是這樣,它的工作
>> from django.apps import apps
>> apps.get_app_config('accounts').get_model('Manager'.lower())
>> accounts.models.Manager
任何亮點爲什麼在遷移時失敗?
