What is the context? Is the drop-down list part of a form based on a table
with a reference to the "cities" table? In general, you can use the
IS_IN_DB validator on a field to automatically generate a drop-down list:
SQLFORM.factory(Field('city', requires=IS_IN_DB(db, 'cities.id',
'%(name)s')))
will produce a form with a drop-down list of the cities in the "cities"
table. The list will include the city names, but the value submitted will
actually be the record ID of the city from the "cities" table.
IS_IN_DB can also be used as the 'requires' argument to Field() in
db.define_table if you have a table that references the "cities" table.
