hello one and all,

you know how when you do a select join and the records come back where you have to access the field values by like db.table1.id or db.table2.last_name?  and i know that under the select we can do like db.table1.ALL and db.table2.last_name, but we still have to access the field values by like db.table1.id or db.table2.last_name?

is there a way to collapse the fields so that we can just use id or last_name, especially when we're certain that the fields are unique when we collapse when we specify the fields under the select?

thank you in advance, lucas

Hi,

I'm not sure to have understand correctly your question, but maybe you need to use aliases:

fields = [
    db.table1.id.with_alias('id'),
    db.table2.last_name.with_alias('last_name')
]

db(yourquery).select(*fields)
