Marlysson,
Thanks for the reply. I did figure out how to do it the web2py way. It was
not particularly intuitive, but now that I understand it, it makes sense
and is pretty powerful.
form=SQLFORM.factory(
Field('hostnames',"list:string",
default=hostnames,widget=SQLFORM.widgets.checkboxes.widget,requires=[IS_IN_SET(hostnames,multiple=True),IS_NOT_EMPTY()]))
form.add_button('Cancel',URL('index'))
Then the view just has {{==form}}
It works exactly the way I hoped it would. Perhaps an example of this
could be put in the examples page.
