Hello
i have a table with integer field.
i populated thhe db from a csv (created from other then me).
it sometimes has empty value for the integers fields.
So when i try to get a list of the records of the table, i got:
type 'exceptions.ValueError'> invalid literal for long() with base 10: ''
from db.py #table prodotti
Field("lunghezza","integer"),
Field("larghezza","integer"),
from default.py
prodotti = legacy_db().select(legacy_db.prodotti.ALL,orderby='prodotti.id
DESC', limitby=limitby)
The error ticket:
