I have this table
db.define_table('evento',
Field('titolo', requires=[IS_NOT_EMPTY()]),
Field('verifica', type='boolean', default=False),
Field('inizio', type='datetime',
requires=IS_DATETIME(format=T('%d/%m/%Y %H:%M'),error_message='deve essere
DD/MM/YYYY HH:MM!')),
Field('fine', type='datetime',
requires=IS_DATETIME(format=T('%d/%m/%Y %H:%M'),error_message='deve essere
DD/MM/YYYY HH:MM!')),
Field('uniqueid', type='string'),
Field('ricorrenza', requires = IS_IN_SET(['0', '1', '2',
'3', '4', '5', '6', '7', '8', '9', '10'], error_message='deve essere un
numero da 0 a 10'), default= '0'),
Field.Virtual('giorno_inizio', lambda
row:calendar.day_name[row.evento.inizio.weekday()]),
Field('risorsa', 'reference risorsa'),
Field('docente', 'reference auth_user'),
Field('materia', 'reference materia'),
Field('studenti', 'list:reference auth_user'),
Field('colore', default = '#8080ff'),
Field('controllato', type='boolean', default=False),
Field('note'),
auth.signature,singular="Evento",plural="Eventi",migrate='evento.table',
format='%(titolo)s')
db.evento.giorno_inizio.represent = lambda giorno_inizio, row:
T(giorno_inizio)
When I create the form I need these requirements to these fields:
db.evento.docente.requires=IS_IN_DB(db(query_docente),'auth_user.id','%(last_name)s'
' ' '%(first_name)s', zero=T('Scegli il docente/referente...'))
and
db.evento.docente.widget = wdg_select
db.evento.materia.widget = wdg_select_change
the field "materia" depends on the field "docente" and it's filled with a
script like:
url_materia = URL("dropdown.html")
script = SCRIPT("""
var url_materia = "%s";
$('#evento_docente').on('change',function(e){
var v = $(this).val();
//alert('Docente cambiato: ' + v);
$.web2py.component(url_materia + '?docente=' + v,
'evento_materia','no','no',$('#evento_materia'));
})
""" % url_materia)
To explain better "docente" is the teacher, and "materia" is the subject.
Every docente has 1 or subject (materia) to teach so when I choose a
"docente" the other field has to be filled only with the subjects teached
by this teacher....
If the field "verifica" is true, I'd like to hidden the fields (BOTH)
"docente" and "materia" and, so, I don't want the requirements. about these
fields...
With a conditional field I can hidden only the "docente" field but if it's
hidden...after submit the form told me that is not correctly filled like
required.
I cannot hidden both field and not consider the requirements if the fields
will be hidden..
Is it possible? Any suggestion?
Thank you
