[web2py] reference field allowing None fields

[Sebastian E. Ovide]

Hi All,

db.define_table('dog',
                Field('owner',db.auth_user))

wont allows me to select an empty user

adding

db.dog.owner.requires = [IS_EMPTY_OR(IS_IN_DB(db,'auth_user.id'))]

would make the drop down menu disappear...

any ideas ?

thanks
