[web2py] db.Table in appadmin when used in a module

[Johann Spies]

I have this in a model. It is included in many tables.

akb_signature = db.Table(db, 'akb_signature',
                     Field('created_on', 'datetime', default = request.now,
                           readable = False, writable = False),
                     Field('created_by', db.auth_user, default =
auth.user_id,
                           readable = False, writable = False),
                     Field('updated_on', 'datetime', default = request.now,
                           readable = False, writable = False),
                     Field('updated_by', db.auth_user, update =
auth.user_id,
                           readable = False, writable = False)
                     )

While migrating table definitions to modules I used it in this way:

class Inst(object):

    def __init__(self, db,):
        self.db = db
        self.T = current.T
        self.auth = current.session.auth
        self.tabelle = ["institution", 'inst_altername']
        self.define_tables()

    def define_tables(self):
        for tbl in self.tabelle:
            if tbl not in self.db.tables:
                if tbl == 'inst_altername':
                    self.inst_alt()
                elif tbl == 'institution':
                    self.institution()
                else:
                    pass

    def institution(self):
        table = self.db.define_table('institution',
                                     Field('name'),
                                    ... several other fields
                                     current.akb_signature_uuid
                                     )

In appadmin I have:

 t = Inst(db)

and it shows the table but when I edit it or insert a new record I get a
ticket:

KeyError: 'akb_signature_uuid'

So how do I expose akb_signature_uuid in this case to appadmin?
