How can I fix KeyError when using requires in web2py Table Field definition with reference type?
I've been trying to set the requires property in a table in a web2py application I've taken over so that the validator will limit the values for the drop-down in the form to a subset of the user accounts. I've read a couple of posts on Google forums, eg https://groups.google.com/forum/#!topic/web2py/n2c3xP6EQ8I, and here suggesting it can be done and I've followed those such that I now have the following field definition in the table:
Field('supervisor', type='reference auth_user', label=T('Supervisor'), requires=IS_EMPTY_OR(IS_IN_DB(db((db.auth_user.is_active == True) & (db.auth_user.id == db.auth_membership.user_id) & (db.auth_membership.group_id != 5)), db.auth_user.id, db.auth_user._format))),
When I run the application though I get an error that says:
<class 'KeyError'> 'id'
I have tried other suggestions like adding:
represent=lambda id, r: '%(first_name)s %(last_name)s' % db.auth_user(id)
to the Field definition but it comes up with the same error.
I've tried breaking the query into two and using the _and option with IS_NOT_IN_DB since it seemed this might give a similar effect:
Field('supervisor', type='reference auth_user', label=T('Supervisor'), requires=IS_EMPTY_OR(IS_IN_DB(db(db.auth_user.is_active == True), db.auth_user.id, db.auth_user._format, _and=IS_NOT_IN_DB(db(db.auth_membership.group_id != 5), db.auth_membership.user_id)))),
Whilst the above doesn't generate an error it also doesn't exclude the unwanted users in the drop-down correctly either. The only thought I had here was that it might be because the the application is using crud to generate the forms instead of explicitly using SQLFORM and a post I saw mentioned that Crud has essentially been dropped in favour of SQLFORM...
For reference my web2py version is 2.17.2 downloaded from source.
Does anyone know how I might fix the field definition to make this work?

Ok, thanks for your help Anthony I appreciate it. The app is pretty old so there could be something else there that's breaking it. A simpler reference works without a problem though so for now I'll just add another column to auth_user as a work around and come back to it later.
