'NoneType' object is not iterable

[tobi]

I have Django trunk with Apache + mod_python.

While trying to access the admin page I got:

TypeError at /admin/
'NoneType' object is not iterable
...
PATH_INFO: u'admin/'

Now I changed django/core/handlers/modpython.py on Line 31 from:

 self.path_info = force_unicode(req.uri[len(root):])

to:

 self.path_info = "/" + force_unicode(req.uri[len(root):])

and everything works fine again.

Looks like your django.root has a trailing slash on it, which is mentioned in the documentation as not the way to go.

If that's not the case, please print out what req.uri is in that case. I can't immediately see why that should be happening and your fix isn't the right approach (it's symptom patching, not fixing the problem).

PythonOption django.root /

was the problem. Removing this line from http.conf fixed it.
Thanks for your fast answer.

The documentation may need to be revised; I don't see where it is mentioned not to have a single / on the django.root. In fact, the current wording makes it very easy to make this mistake:

Quoted from ​How to use Django with mod_python:

The value set on that line (the last item) should match the string given in the <Location ...> directive.
