Hi
I'm having a problem with a SingleSelectField. It's probably more of a
problem with my understanding of when things are loaded, but I was
hoping someone could explain this to me a bit.
I have the following form:
------------------------------------------------
class FormFields(WidgetsList):
name = TextField(label='Name:', validator=validators.NotEmpty)
district = SingleSelectField(label='District:',
options=qOptions.getDistrictOptions('None'),
validator=validators.All(validators.NotEmpty(), validators.Int()))
testForm = TableForm(fields=FormFields(), submit_text='Save Changes')
------------------------------------------------
And, I have the following method to fill the SingleSelectField in the
qOptions module:
------------------------------------------------
def getDistrictOptions(allNone='None'):
ds = District.select(orderBy='name')
options = [('', '-- %s --' % (allNone))]
for d in ds:
name = d.name
if d.salesman:
name = '%s - %s' % (name, d.salesman.display_name)
options.append((d.id, '%s' % (name)))
return options
------------------------------------------------
This works fine, except if I make a change to the salesman assigned to a
district. If I do, I still get the old salesman name in the dropdown
even though it has been changed. If I restart the server I then get the
correct salesman name. I use this pattern all over in my application,
but without the foreign key lookup and getting the name from the related
table. In these SingleSelectFields, changes to the table takes effect
immediately and doesn't require a restart.
Can someone help me understand why this is happening?
Thanks!
-Jim
