I need to fill in a combo with contacts,
these contacts depend of the service_id I get from the URL
I first define my own SingleSelectField class and define the
"update_params"
class ContactSelect(forms.SingleSelectField):
def update_params(self, d):
d['options']=tg.request.contact_list
forms.SingleSelectField.update_params(self, d)
This is bad style, use
super(ContactSelect, self).update_params(d)
in such cases. For a different solution in general, see below.
return d
I use the tg.request.contact_list to initialize my list.
I have previously build this list in my controller
in my controller
@expose('project.templates.monitor')
def new(self, service_id, *args, **kwarg):
...
tg.request.contact_list=get_contacts_for_service(service_id)
...
return dict(
....
)
This is simple and efficient but I dont like the way I do it !
- their could be a name conflict with other variable in tg.request.*
maybe I could use another tg or pylon "container" to store my
contact_list ?
- The ContactSelect class is not very easy to package
Any better way ?
Use the tmpl_context. And use a callable to options instead:
SingleSelect("contacts", options=lambda:
tmpl_context.contacts_for_service)
@expose(...)
def new(...):
tmpl_context.contacts_for_service =
get_contacts_for_service(service_id)
