It does not work because this db.t.f1 is a field (a column) not a
value (true or false).
I guess what you want is make the second field readable or writable
depending on which record you are looking at. For example it makes no
sense if you are inserting a new record, should the second field be
editable or not?
That requires that you do it in controllers for example:
def edit_t():
record = db.t(request.args(0))
if record: db.t.f2.writable = record.f1
else db.t2.writable = true
form = SQLFORM(db.t, record).process()
return dict(form=form)
