I think we need some debugging. His code is
def hello():
form = SQLFORM(db.easy_test)
if form.accepts(request.vars, session):
request.flash = 'ok'
return dict(form=form)
and web2py returns a list with a string in this case (the generic view
that renders the dict()). I do not see how web2py can return anything
else.
