I have two tables which read like:
db.define_table('facility',
db.Field
('facility',length=42,default='',notnull=True,unique=True),
db.Field('in_widget',type='boolean',default=False,notnull=True),
migrate='facility.table')
db.define_table('facilitytime',
db.Field
('company',db.company,default='',notnull=True,ondelete='CASCADE'),
db.Field('facility',length=42,default='',notnull=True),
db.Field
('day',db.dag,default='',notnull=True,ondelete='RESTRICT'),
db.Field('from_time',type='time',default='',notnull=True),
db.Field('to_time',type='time',default='',notnull=True),
db.Field('created_on',type='datetime'),
db.Field('modified_on',type='datetime'),
migrate='facilitytime.table')
Field facility in table facilitytime should be a options widget based
on the facility field in table facility. The facility should only be
contained in the widget when in_widget is True and key and value
should read the same.
I searched the group for an example but I couldn't find one I
completely understand.
I suppose in the model I need something like:
db.facilitytime.facility.widget=lambda f,v: facilitywidget(f,v,...)
the ... should be replaced with the facilities from this SQLRows
object:
facilityrows=db(db.faciliteit.in_widget==True).select
(db.faciliteit.faciliteit)
The widget should go in a module:
def facilitywidget(field,value,options):
id='%s_%s' % (field._tablename,field.name)
else: raise SyntaxError, "widget cannot determine options"
opts+=[OPTION(v,_value=k) for k,v in options]
return SELECT(*opts,**dict
(_id=id,_class=field.type,_name=field.name,value=value,requires=field.requires))
I hope one of you knows how to build this widget.
Kind regards,
Annet.
