I am trying to sanitise data from different sources programatically.
The following function is part of my effort:
def artikel(datum,ti,wod_id,publ_id,di):
titel = ti.strip().upper()
if db(db.artikel.titel == titel).count() < 1: # Is titel
already in database?
artikel_id = db.artikel.insert(titel = titel,
publikasie_id = publ_id,
wos_id = wos_id,
datum = datum,
id_nr = di.strip().upper()) #
insert if not.
else: # get the id if it is already there
artikel_id = db(db.artikel.titel == titel).select()[0].id
return(artikel_id)
It tries to determine whether there is already such a value for
'titel'. If it is not already there, insert the record, else get the
id.
But this function fails at the line after "else:" with:
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/home/js/web2py/gluon/sql.py", line 2987, in select
return self.parse(db,rows,self.colnames)
File "/home/js/web2py/gluon/sql.py", line 3034, in parse
str(value)[:10].strip().split('-')]
ValueError: need more than 1 value to unpack
What is the best way of doing this?
Should I create a unique index on field "titel" and then insert with a
"try ... except" ?
Regards
Johann
