You just change this:
def rp(author):
an =
db(db.akb_reprint.uuid==author).select(db.akb_reprint.rp_author)
if len(an):
a_name = an.first()['rp_author']
else:
a_name = 'No rp_author'
return a_name
into this:
def rp(author,record):
an =
db(db.akb_reprint.uuid==author).select(db.akb_reprint.rp_author)
if len(an):
a_name = an.first()['rp_author']
else:
a_name = 'No rp_author'
return a_name
or
def rp(author,record):
row =
db(db.akb_reprint.uuid==author).select(db.akb_reprint.rp_author).first()
return row and row.rp_author or 'No author'
and use it as
db.akb_articles.rp_author.represent = rp
In this case you would not need record.
