Hello,
I am just starting out in w2p. Could you please advise how to approach this
kind of scenario?
I need a following db design:
db.define_table('person',
Field('first_name'),
Field('last_name'),
format='%(last_name)s, %(first_name)s')
db.define_table('client',
Field('person_id', 'reference person'),
format=lambda r: '%s, %s' % (r.person.last_name, r.person.
first_name))
db.define_table('student',
Field('person_id', 'reference person'),
Field('client_id', 'reference client'),
format=lambda r: '%s, %s' % (r.person.last_name, r.person.
first_name))
The student table has references to both client and person table. The
client table references person as well.
I don't fully understand why I get AttributeError when trying to add the
student field in Admin DB interface. Why the client record has no person
attribute? If I change the format of the client table to say "lambda r:
str(r)", I am able to see both person and client dropdown boxes properly
and able to add the fields. How to show the person in the client reference?
