Very sorry everybody: I googled around tons, but I didn't search this group! LOL. I'll know next time.
Adding an "invalid" choice to a ChoiceField? http://groups.google.com/group/django-users/browse_thread/thread/dd6d8eb11f915c94/77aa6fbea94af4c4?lnk=gst&q=choicefield#77aa6fbea94af4c4 This works: colours = (('','Please choose a colour:'),('r','Red'), ('g','Green'),('b','Blue)) # ... fave_colour = forms.ChoiceField(choices=colours) Django's automagical form validation means the form cannot be submitted without choosing a colour, and somehow (because empty string always sorts before anything else?) the 'invalid' choice is displayed by default and can act as a prompt.
