About OPTGROUP, here is an example.
CHINA={
'CAN':'Guangzhou',
'SHA':'Shanghai',
'PEK':'Beijing(Peking)',}
INTERNATIONAL = {
'SYD':'Sydney',
'BKK':'Bankok',
}
AIRPORTS = dict(CHINA.items() + INTERNATIONAL.items())
db.define_table('booking',
Field('departure', requires=IS_IN_SET(AIRPORTS)),
...,
)
# so far, nothing is new. Then...
from gluon.sqlhtml import OptionsWidget
class GroupOptionsWidget(OptionsWidget):
def __init__(self, groups):
self.groups = groups
def widget(self, field, value, **attributes):
attr = OptionsWidget._attributes(field, {'value':value},
**attributes)
opts = [OPTION('')] + [ OPTGROUP( # OPTGROUP(...) is available
since web2py 1.77.4
_label=group, *[OPTION(v, _value=k) for (k, v) in
options.items()])
for group, options in self.groups.items() ]
return SELECT(*opts, **attr)
db.booking.departure.widget = GroupOptionsWidget({'China':CHINA,
'International':INTERNATIONAL}).widget
# That is it.
# I know it is not cool that we need to define our own
GroupOptionsWidget every time. But if there is enough interest, I
guess we can do more to enhance the already-too-complicated
IS_IN_SET(...), to support following pattern:
Field('departure',
IS_IN_SET( {'China':CHINA, 'International':INTERNATIONAL} ) )
I mean, a dict of dicts should automatically trigger a predefined
GroupOptionsWidget.
