我正在尝试创建一个将使用 django ORM 工具的脚本。我也会有一个轻量级的网络界面。

现在，当我运行时：

python manage.py runserver

我可以去 localhost 浏览我的应用程序，添加一些数据，修改等。没问题。但是，当我创建如下脚本时：

import sys
import os
sys.path.append('C:\\hg\eclipse_workspace\dj_MNH')
os.environ["DJANGO_SETTINGS_MODULE"] = "dj_MNH.settings"
from SeN.models import Deliveries as table

def process():
    """ quick test """

    d = table.objects.get(nve_filename='test')
    print d.nve_filetime
    print table.objects.all()


if __name__ == "__main__":
    process()

我在下面得到以下回溯。我有另一个类似配置的 django 项目，它以相同的方式工作，没有问题！我可以打开我的 sqlite 数据库，看看那里也有一些数据......关于什么/如何调试的任何想法？
