Field('is_correct', 'boolean', default=False)
In the form you get a checkbox widget unless you choose otherwise.
In the controller:
if form.vars.is_correct:
# do something
else:
#do otherwise
Less typing.
Also, look in your database back end and see how it represents the values.
You will find they are surrounded by pipe characters. Web2py is using
them for list separators because it expects you to store multiple values in
the field.
Is that what you want to do?
