Question

I am trying to use session to pass some data from one page to another page. Here is the code i wrote in ajax.py.

def save_cookie(request, query):
    request.session[ query ] = query

But when i call this dajaxice function.An error will occurred. As we all know that when we try to use dajaxice in html page, the error msg always is "sth goes wrong". I tried to debug save_cookie, but the mock request object i created has no session attr. However, if i do request.session="blah", it worked. If I directly use save_cookie(request,query). It will pop up the error msg that request object has no attr seesion...

代码是直截了当的,我没有看到任何错误,有人知道原因吗?

Answer 1

从未使用 Dajaxice / dajax 来帮助我。只有几个点:

您是否为届会提供支持( 并适当地与您联系)? < a href="https://docs.djangoproject.com/en/1.3/topics/http/sessions/"rel="nolfollow" >https://docs.djangoproject.com/en/1.3/topics/http/sessions/
您可以使用记录模块(或简单的“打印”语句)追踪例外, 即:

def save_cookie(request, query): try: request.session[ query ] = query except Exception, e: print e raise

打印语句的输出现在应该出现在您启动 Dev 服务器的 shell 中( 假设您与 Dev 服务器一起工作... 您与 Dev 服务器一起工作, 是不是? )

仍然使用 dev 服务器, 您可以使用 pdb 切换到交互式调试 :

def save_cookie(request, query): import pdb; pdb.set_trace() request.session[ query ] = query

然后尝试访问浏览器中的 URL, 切换到您的 shell, 然后在 pdb 会话中您可以检查请求并( 如果有的话) 请求. session objects etc.

NB:如果在阿帕奇或其他任何网络服务器后面运行,则不要这样做,只使用内建的dev服务器。

"request.session= blah " will create the "session" attribute on the "request" object if it doesn t exist (and possibly replace the real "session" object if it already existed), so it s neither a valid test nor something sensible to do

我的两分钱...

我对Dajaxice一无所知

下列人员将研究模拟请求对象:

def save_cookie(request, query):
    if not hasattr(request,  session ):
        request.session = dict()
    request.session[ query ] = query
