You can either assign a callable to options that returns an update to
date list of items or pass them in at display time. To use a callable
do something like this:
#Define the callable somewhere
def get_item_list():
return [(item.id, item.name) for item in
model.Item.select(model.Item.q.active == True, orderBy='name')]
#Define the items like this
items = widgets.CheckBoxList(validator=validators.Int(), options=get_item_list)
