Good tip Wikus..
you can also do the something similar with SQLFORM.factory and not
define in the model (that way no DB table is created)
in controller
--------------------------------
MY_OPTIONS = ["a","b","c"]
form = SQLFORM.factory(
Field("my_options", "list:string",
default=MY_OPTIONS,widget=SQLFORM.widgets.checkboxes.widget,
requires=[IS_IN_SET(MY_OPTIONS,
multiple=True),IS_NOT_EMPTY()]))
if form.accepts(request.vars):
#code to process form
return dict(form=form)
