我完全不明白这个错误。我使用django-nonrel,通过manage.py将其上传到我的应用程序。 有时我有这个:
<type 'exceptions.AttributeError'>: 'Settings' object has no attribute 'DATABASE_ROUTERS'
Traceback (most recent call last):

或

路径有什么问题?为什么会这样?首先路径为“/base/data/home/apps/app-id/3.347046818251769742/django/”,然后是“/base/python_runtime/python_lib/versions/third_party/django-0.96/django/".
以及如何避免这个错误?
我已经检查过sys.path,上传了几次新的django,删除了所有不必要的文件,我迷路了:(
sys.path = ['/base/data/home/apps/appid/3.347077364008022180',
'/base/data/home/apps/appid/3.347077364008022180/djangoappengine/lib',
'/base/python_runtime/python_dist/lib/python25.zip',
'/base/python_runtime/python_dist/lib/python2.5/',
'/base/python_runtime/python_dist/lib/python2.5/plat-linux2',
'/base/python_runtime/python_dist/lib/python2.5/lib-tk',
'/base/python_runtime/python_dist/lib/python2.5/lib-dynload',
'/base/python_runtime/python_lib/versions/1',
'/base/data/home/apps/appid/3.347077364008022180/']
答案 0 :(得分:0)
我猜db/__init__.py
做from django.conf import Settings
之类的事情,无论出于何种原因,它有时会被赋予系统的Django版本而不是你自己的版本。
您可以尝试将其更改为使用相对导入,例如from ..conf import Settings
,这应该意味着它使用相同包中的版本。这适用于Python 2.5,这是Appengine使用的。
