I found the Djaneiro plugin super useful. It adds syntax highlighting for Django HTML templates and comes with a bunch of handy code completion snippets:
For example, you can type if
, hit Tab
, and Djaneiro creates a complete {% if ___ %} {% endif %}
block for you automatically.
I guess it depends on one's definition of "auto-complete" but I really like the snippets added by Djaneiro. I use it in combination with the Anaconda plugin for code completion and I'm very happy with this setup for Django development.
I actually wrote a review of Djaneiro and its features a while ago. You can find it here if you're interested: https://dbader.org/blog/sublime-text-djaneiro-review
