81	Setting primary_key=True on an non-integer field isn't yet supported	jmb@…	Adrian Holovaty	"The admin interface appears to want to keep the primary_key numerical, and so breaks if you have set a field as primary_key=True.


Model:

{{{
class Airfield(meta.Model):
    fields = (
        meta.CharField('code', 'airfield code', maxlength=4, primary_key=True),
        meta.CharField('name', 'name', maxlength=50),
    )
    admin = meta.Admin(
        fields = (
            (None, {'fields': ('code', 'name')}),
        ),
    )
    def __repr__(self):
        return self.name
}}}
