You could also just write your own signature:
def lazy_user (auth = self): return auth.user_id
reference_user = 'reference %s' % settings.table_user_name
def represent(id,record=None,s=settings):
try:
user = s.table_user(id)
return '%(first_name)s %(last_name)s' % user
except: return id
self.signature = db.Table(self.db,'auth_signature',
Field('is_active','boolean',default=True),
Field('created_on','datetime',
default=request.now,
writable=False,readable=False),
Field('created_by',
reference_user,
default=lazy_user,represent=represent,
writable=False,readable=False,
),
Field('modified_on','datetime',
update=request.now,default=request.now,
writable=False,readable=False),
Field('modified_by',
reference_user,represent=represent,
default=lazy_user,update=lazy_user,
writable=False,readable=False))
