金字塔女服务员1.4

Question

我有一个用Python2.7.5编写的程序，我想把它移到我在webfection上托管的帐户上。在那里我想用Pyramid 1.4/python2.7实现它。我已经安装了所有的包，但似乎我有一个金字塔本身的问题。下面是我得到的错误列表。

md5, sys, os, tempfile, json, re, urllib2, time, multiprocessing requests

2013-10-18 21:37:48,821 ERROR [waitress][Dummy-1] Exception when serving /

  File "/home/.../lib/python2.7/waitress/buffers.py", line 243, in append
    self.strbuf = strbuf + s
TypeError: cannot concatenate 'str' and 'list' objects

如何调试这个有什么建议吗？

Answer 1

解决办法很简单，但不是那么明显。在视图.py我看到了一个正在回归的景象

Response(x)

其中x是我的多进程代码的输出，但它也是一个列表。这引起了一个问题。最后我使用render_to_response并将结果作为字典的一部分传递
