You know what's weird? I've used simplejson.dumps() plenty of times
in my own code... not sure why that one just slipped out of my
memory. I should just stop responding to things :-)
Anyway, since you're serializing a model, you *should* be using your
originally posted method. Use the way Marek said for anything other
than models (of course, the object has to be serializable.)
If that doesn't work, post the full (relevant) code.
