Hi,

I'm currently working through Django by Examples and I am getting an error when attempting to have the user automatically go back to the listing of 'todo items' after entering new 'to do items' through creating a new date. The site asks us to copy a function from a template provided by django, and alter a couple of things. The code example and the template are a bit different post altering though (I guess this is because I am using 1.4;s default packages and presumably the author was using 1.2), but I don't think these are relevant to my problem (I use in rather than has.key etc)

Name Error at /admin/todo/datetime/add/
global name 'escape' is not defined

I think you want to add this import statement:
from django.utils.html import escape

Ah, thanks. Maybe it's time to start using eclipse.
