Question

我正在尝试将一个SMTP实时服务器作为django中的单独应用程序。每当我尝试运行smtp文件python smtp.py来监听传入的消息并将它们存储在模型中时，我都会收到ImproperlyConfigured错误。

smtp.py

import os
import smtpd
import asyncore
import datetime
from models import IncomingEmail
from email.parser import Parser

class MessageServer():
    def __call__(self, peer, mailfrom, recipients, data):

        email = Parser().parsestr(data)

        incomingDb = IncomingEmail(
                sender=mailfrom, recipient=recipients,
                message=data, subject=email['subject'],
                recevied=datetime.datetime.now()
                )
        incomingDb.save()

class customSMTPServer(smtpd.SMTPServer):
    process_message = MessageServer()

if __name__ ==  "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "hello.settings")
    server = customSMTPServer(('localhost', 1025), None)
    print "Started listening at port 1025"
    try:
        asyncore.loop()
    except KeyboardInterrupt:
        server.close()

项目结构：

hello/
 manage.py
 hello/
  __init__.py
  settings.py
  urls.py
  wsgi.py
 smtp/
  smtp.py
  models.py
  __init__.py
 api/
  admin.py
  apps.py
  urls.py
  views.py

错误：

django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environ
ment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

看起来你收到了这个错误，因为DB engin缺少一些重要的设置。如果您编辑这样的代码怎么办？

import sys, os
sys.path.append('/path/to/your/app')
os.environ['DJANGO_SETTINGS_MODULE'] = 'hello.settings'
from django.conf import settings
print "Started listening at port 1025"
...

或者另一种方法是尝试在文件顶部移动os.environ.setdefault("DJANGO_SETTINGS_MODULE", "hello.settings")（当然，在导入os之后）另一个有点脏的黑客是：

if __name__ == "__main__":
    from django.core.management import execute_from_command_line    
    execute_from_command_line(sys.argv)

接下来你可以试试：

$ ./manage.py shell
...
>>> execfile('your_script.py')

另外，哪一行抛出异常？

NotperlyConfigured：请求设置DEFAULT_INDEX_TABLESPACE，但未配置设置
