Re: How do I populate a multi-select field with a single column from a model?

Ah... Well that's exactly what's happening. I'm getting "Area Object"
for each element in the select box. I've seen the __unicode__ method
on a few model examples, but my book and other resources never really
showed or explained it. I'll see if I can find some explanation of it.
Thanks for the clue.
