[web2py] Re: change represent of referenced filed in SQLFORM update
Thanks for the help, it works. However, this alters the table definition.
1) Is there a way that the value is only set temporarily ?
2) When the address field is empty, can I use other fields , like city,
country and etc?

[web2py] Re: change represent of referenced filed in SQLFORM update
The "represent" attribute controls the display of read-only data in grids
and read-only forms (or read-only fields). The values shown in the select
element in a form are controlled by the validator, which defaults to
IS_IN_DB for a reference field. The values shown in the select element
(generated by the validator) as well as the "represent" attribute are
controlled by the "format" argument in the definition of the referenced
table, so the simplest approach is to change that:
db.define_table('customer',
...,
format='%(name)s, %(address)s, %(city)s')
Alternatively, you can explicitly set your own validator for the reference
field:
Field('customer', 'reference customer',
requires=IS_IN_DB(db, 'customer.id', '%(name)s, %(address)s,
%(city)s'))
