Komodo Edit - code-completion for Django?
Hmmm. It's installed by default so my answer probably isn't the right solution. :-)
But here goes...
You can install a Django extension in Komodo edit. I haven't tested it myself but you can test it.

Tools -> Add-ons -> Extensions

It's name is "Django Language".
Check if it works.
I've been using Komodo Edit for a small project in Django.
The code completion features seem to work pretty well for standard python modules, however, it doesn't know anything about Django modules.   Is there any way to configure Komodo Edit to use Django modules for autocomplete as well?
