This is what I was looking for.... Thanks Ross... But the correct should be:
db.user.account = Field.Virtual(lambda row: row.user.account_id) The Book seems to be wrong also: db.item.total_price = Field.Virtual(lambda row: row.unit_price*row.quantity) should be: db.item.total_price = Field.Virtual(lambda row: row.item.unit_price*row.item.quantity) Thanks, Marcello On Tue, Jan 10, 2012 at 12:58 PM, Ross Peoples <[email protected]>wrote: > You might be able to do something like this to trick it into being a > virtual field: > > db.user.account = Field.Virtual(lambda row: row.account_id) > > This just makes a virtual field "account" which returns the value of > "account_id". This will only work with reads, though. If you try to set a > value to db.user.account, it will not work, you have to set it to > db.user.account_id. > >
