Hello,
I was looking the book http://www.web2py.com/books/default/chapter/29/06
And intrested with:
New style virtual fields (experimental)
Create model.db with:
db.define_table('item',
Field('unit_price','double'),
Field('quantity','integer'))
db.item.total_price = Field.Virtual(lambda row: row.unit_price*row.quantity)
Open database admin and insert some numbers
but the table view gives only flash with:
'Row' object has no attribute 'unit_price'
and no data.
Please correct my mistake,
I think I missed something.
Thanks,
Maxim
