getting 'NoneType' object is unsubscriptable errors

[saureen adani]

Hi,

I am getting the following errors on some of the web pages

-----------------------------------------------------------

'NoneType' object is unsubscriptable

Request Method: GET
Request URL: http://nerd.hoonur.com/mypage/4605f1e14430950e07b74b5374472f00

-----------------------------------------------------------

I tried putting the code line where the error was occuring under
try-catch-exception but still the error exits.

What could be the reason for the above error and possible solution to get
rid of above error?

Help would be highly appreciated !

You didn't think it would be useful to show us some of the actual code?

Although to be honest, if your views.py is over 2570 lines long, you've got more problems than we can sort here.

This error occurs when you attempt to subscript a variable that is None.

IE:

>>> a=None
>>> a[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'NoneType' object is unsubscriptable

Don't try to index into a list without verifying that it is a list.

Cheers
