The Django Toolbox for Komodo does most of what the TextMate bundles do, plus integrated shortcuts for the most important links in the Django docs. Builtin template filter support is still a work in progress.
To get the most out of the toolbox, first install the Tab Abbreviations add-on and set a keyboard shortcut (eg. TAB) to the command “Insert Abbreviation Snippet By Name”.
