Python-django

Python-django (in MELPA, by the creator of python-mode) has the following features:

• File navigation (per app, STATIC_ROOT, MEDIA_ROOT and TEMPLATE_DIRS),
• Etag building,
• Grep in project,
• Quick jump (to settings, project root, virtualenv and docs),
• Management commands: You can run any management command from the project buffer via python-django-mgmt-run-command or via the quick management commands accesible from the Django menu. Completion is provided for all arguments and you can cycle through opened management command process buffers very easily. `sql-mode' will be used.
• Quick management commands.

Another cool feature is that comint processes (the general mode for repls) are spiced up with special processing, for instance if you are using runserver and get a breakpoint via pdb or ipdb then the pdb-tracking provided by python-mode will trigger or if you enter dbshell the proper sql-mode will be used.
