[web2py] Re: Record representation : multiple levels of references

You can use a lambda:

db.define_table('other_table',
Field('key_id', 'reference key',
  requires=IS_IN_DB(db, 'key.id', lambda r: '%s %s (%s)' % (r.
person_id.first_name,
r.
person_id.last_name, r.id

 Say I have a table like this:

 Now if I build a new table:

 db.define_table('key', Field('person_id', 'reference person', 
 requires=IS_IN_DB(db, db.person, label=db.person._format)))

 My new table 'key' will represent its references using 'person' table's 
 format.


 But what if I have another table like this:

 db.define_table('other_table', Field('key_id', 'reference key', 
 requires=IS_IN_DB(db, db.key, label='%(first_name)s %(last_name)s 
 (%(key_id)s)'???)))


 How do I define the label in 'other_table' so that it shows the 'person' 
 that this key is actually referring to ?
