I'm just working my way through Django, and really liking it so far, but I have an issue and I'm not sure what the typical way to solve it. Suppose I have a View which is supposed to be updated when some complex Python object is updated, but this object is not driven by the database, say it is driven by AJAX calls or directly by the use...

I asked this question on the PyQt mailing list, and didn't get any responses, so I'll try my luck here.
