How can I make the 'barcode' field in bursary_entries reference/depend upon
a 'barcode' entry in bursary_users? Do I just have to alter my field to:
type='text', requires=IS_IN_DB(db,'bursary_users.barcode)
I was trying to make sense of what was needed here and I thought 'requires'
was the best way of doing it, but does that only work for the primary key?
Thanks for your help.
