Django開發學習BUG記錄--RemovedInDjango19Warning:Model class apps.user.models.User doesn't declare an explicit app_label

報錯信息：

/home/python/PycharmProjects/dailyfresh/apps/user/models.py:8: RemovedInDjango19Warning: Model class apps.user.models.User doesn't declare an explicit app_label and either isn't in an application in INSTALLED_APPS or else was imported before its application was loaded. This will no longer be supported in Django 1.9.

• 報錯解析：apps.user.models 沒有聲明

原因：當時創建項目時為了簡化注冊app的寫法，所以在setting中加入了apps的路徑

sys.path.insert(0, os.path.join(BASE_DIR,'apps'))

然后注冊app時就不用apps.

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'tinymce',
    'cart',
    'goods',
    'order',
    'user',
)

但是當在user.views導入user.models時直接導入

from user.models import User

按這樣導入pycharm會有紅色波浪線提示，所以又改回原始寫法

from apps.user.models import User

這樣開啟服務器后就會出現上面的報錯

這樣就會導致Django注冊時app為user,但導入使用時是apps.user，所以Django沒有找到對應聲明的app所以報錯

• 解決方法：

方法1.忽略pycharm報錯，還是直接導入

 

from user.models import User

 

方法2：注冊app時不簡化寫法時用apps.注冊
