It appears you're using a method called entity(), which would return a handle
to the current table called "tf_user" in this case. To modify a row, you need
to load the row first. You do this with filter(), first(), one(), etc. It
seems here you're tacking on the word "hello" to the query object itself which
would have no effect. Examples of loading actual rows at
http://www.sqlalchemy.org/docs/reference/ext/sqlsoup.html?highlight=sqlsoup#loading-objects.
The tutorial here seems to use the special variable "_", which is
unfortunate (I didn't write any of this), but it implies the row that was
previously loaded via one(). thats the thing you change.
