I think there is, but currently I've came up with:
def year():
# too many - fail
if len(request.args) > 1:
redirect(URL(r=request,args=[]))
# init
table = db.year_year
app_settings = AppSettings()
arg0 = None
if len(request.args) == 1:
arg0 = request.args[0]
if arg0 == 'add':
def update_settings(form):
requested = form.request_vars.newyear
if not app_settings['min_year']:
requested = form.vars.year
app_settings['min_year'] = requested
app_settings['max_year'] = requested
app_settings.commit()
def onvalidate_addyear(form):
if app_settings['max_year']:
next = str(int(app_settings['max_year']) + 1)
requested = form.request_vars.newyear
if next and requested != next:
if requested <= next:
session.flash = \
"The year %s has already been added" % requested
else:
session.flash = \
"The year %s does not follow %s" % (requested, next)
redirect(URL(r=request, args=['add']))
form.vars.year = requested
default = dict(
table = table,
onaccept = update_settings,
onvalidation = onvalidate_addyear
)
if app_settings['min_year'] == None:
# no years yet - need to add first
form = crud.create(**default)
return dict(form = form)
else:
newyear = int(app_settings['max_year']) + 1
table.year.writeable = False
table.year.default = newyear
form = crud.create(**default)
# add field to hold value for input
form.append(INPUT(_type='hidden', _value=newyear, _name =
'newyear'))
return dict(form = form)
# no add
rows = db().select(table.ALL)
all_years = extract_field(rows, 'year')
if arg0 and int(arg0) and \
arg0 >= app_settings['min_year'] and arg0 <=
app_settings['max_year']:
form = crud.read(table, rows[all_years.index(arg0)])
return dict(form = form)
elif arg0:
redirect(URL(r=request,args=[]))
return dict(app = app_settings.row, years = all_years)
