I want to negate a value with this expression:
db(db.table.lft > 0).update(lft = 0 - db.table.lft) but I get the following TypeError: TypeError: unsupported operand type(s) for -: 'int' and 'Field' My workaround is: db(db.table.lft > 0).update(lft = db.table.lft - db.table.lft - db.table.lft) *It seems that update expression need to start with the field or do I miss something?* -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
