但是，在配置 mod_python/apache 或 wsgi/apache 时，我是新手。

我已经能够使用 python 调试器工具..pdb.set_trace()成功，特别是在使用 django 开发服务器时，即它向终端输出所有服务器活动，包括 pdb 接口。

那么，当尝试在 webfaction 等主机上部署 django 网站时，如何做这样的事情呢？

除了 ftp 进入 error_log 并阅读有关它的故障后，是否能够与系统交互，因为它正在发生？

希望我在这里足够清楚。

顺便说一句，以下是我要配置的文件。

import os
import sys

from os.path import abspath, dirname, join
from site import addsitedir

from django.core.handlers.modpython import ModPythonHandler

import pdb

class PinaxModPythonHandler(ModPythonHandler):
    def __call__(self, req):
        # mod_python fakes the environ, and thus doesn't process SetEnv. 
        # This fixes that. Django will call this again since there is no way
        # of overriding __call__ to just process the request.
        os.environ.update(req.subprocess_env)
        from django.conf import settings

        sys.path.insert(0, abspath(join(dirname(__file__), "../../")))

        sys.path.insert(0, os.path.join(settings.PINAX_ROOT, "apps/external_apps"))
        sys.path.insert(0, os.path.join(settings.PINAX_ROOT, "apps/local_apps"))

        sys.path.insert(0, join(settings.PINAX_ROOT, "apps"))
        sys.path.insert(0, join(settings.PROJECT_ROOT, "apps"))
        pdb.set_trace()

        return super(PinaxModPythonHandler, self).__call__(req)

def handler(req):
    # mod_python hooks into this function.
    return PinaxModPythonHandler()(req)

这是通过http产生的错误页面：

mod_wsgi 站点上记录了如何将 pdb 与 mod_wsgi 一起使用。看：

http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Python_Interactive_Debugger

其他调试技术显示在同一页面上。
