Note, the Rows class already has .first, .last, .find, .sort, and .exclude methods -- we've just added one more such method. Hopefully most folks will recognize that because .select() returns a Rows object, any subsequent method calls must be operating on the Rows object. Those who don't may also have trouble figuring out the more explicit list comprehension/generator expression code (which prompted this thread to begin with). To make things more clear, you can do:
rows = db().select(db.mytable.myfield) values = rows.column() Anthony On Wednesday, May 28, 2014 5:23:09 PM UTC-4, Leonel Câmara wrote: > > I don't like this new method.
