Since you are using datatable you do not have mach choice and you have to
handle this serverside. You want the json to contain the nationality
description instead of the nationality id. This can be done in the
controller.
Before you do that two observation: User is a reserved keywork so I am
going to use Person. Table Nationality should be defined before table
Person to avoid trouble. So, given:
db.define_table('Person',
Field('first_name', 'string'),
Field('last_name', 'string'),
Field('email','string'),
Field('username','string'),
Field('nationality','reference Nationality', requires =
IS_IN_DB(db,db.Nationality.id,'%(description)s')
)
db.define_table('Nationality',
Field('description','string'),
format = '%(description)s'
)
You can do:
def user():
import json
rows = jdb(db.Person.id>0).select()
ids = [row.nationality for row in rows] # find the nationalities
mapping = db(db.Nationality.id.belongs(ids)).select().as_dict() # build
a mapping in one extra query
for row in rows: row.nationality=mapping[row.nationality].description #
applly the mapping
return dict(formListar=XML(rows.as_json()))
