报错信息：
/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.
- 报错解析：apps.user.models 没有声明
原因：当时创建项目时为了简化注册app的写法，所以在setting中加入了apps的路径
sys.path.insert(0, os.path.join(BASE_DIR,'apps'))
然后注册app时就不用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',
)
但是当在user.views导入user.models时直接导入
from user.models import User
按这样导入pycharm会有红色波浪线提示，所以又改回原始写法
from apps.user.models import User
这样开启服务器后就会出现上面的报错
这样就会导致Django注册时app为user,但导入使用时是apps.user，所以Django没有找到对应声明的app所以报错
- 解决方法：
方法1.忽略pycharm报错，还是直接导入
from user.models import User
方法2：注册app时不简化写法时用apps.注册
