Okay, after reading http://groups.google.com/group/turbogears/browse_thread/thread/ee62cdd368a83ebc I think I have a solution. Firstly, I changed the options-filling callback to: def opt_skills(): return [(s, s.name) for s in Skill.select()] Next, I added a __str__ to Skill that returned its ID. And now it seems to work. It looks like convert=True also takes care of converting the options list items. With the __str__ solution, I lose the ability to have Skill instances render as their name when displayed, but that I can work-around. I can remove the __str__ and change CoerceSkill to: def _to_python(self, value, state): try: id = int(value) params = dict(id=id) except: params = dict(name=value) return Skill.get_by(**params) Is this the worst kind of kludge?
