The IS_IN_SET validator allows to list the options as a dictionary (
http://web2py.com/books/default/chapter/29/07/forms-and-validators?search=IS_IN_SET
)
Therefore, for an example, you could do:
def index():
options = {'Apple':T('Apple'),'Banana':T('Banana'),'Cherry':T('Cherry')}
form=SQLFORM.factory(Field('fruit',requires=IS_IN_SET(options,zero=None
)))
if form.accepts(request, session):
selected = options[form.vars.fruit]
saved = form.vars.fruit
response.flash='selected %s in drop down list, saved %s in db' %(
selected, saved)
return dict(form=form)
