Could you clarify what you mean by "ambiguous as to the treatment of underscores"? I don't see an ambiguity, so I wonder what I'm missing. My understanding is that a slug is usable as a URL; that's really the syntax definition, and is why it is limited to "only letters, numbers, underscores or hyphens." A slug is effectively an artifact of Django's birth in journalism-on-the-web, and an extraordinarily handy one. As such, it exists for practical reasons, rather than purity. > Naturally, I'm wanting to use a slug to identify some model instances > based on some other model field.

I override the model's save method, and populate the slug field prior to allowing the save to proceed. I picked up that trick from some other code somewhere; it isn't uncommon.
