ok, it look like I was too tired yesterday night :)
It doesn't work with default schema but with the deferred one it works
smoothly.
Sorry for the noise :P
Anyway, I wonder if this should not be a default behaviour: if the form
renderer find a 'request' element just try to get the value from there?
Wouldn't be useful?

Hi all,
I'm quite new to pyramid and deform and I'm trying to achieve
something very simple that I suppose should work OOTB but I can't get
it working.
I have a simple schema-based form and I want the fields to get the
selected value from the request once submitted.
Here's the schema:
class MySchema(colander.MappingSchema):
department = colander.SchemaNode(
colander.String(),
default='',
widget=SelectWidget(values=departments),
)
where choices come from an external db trough sqlalchemy. The form
works but on every submit it lose selected value.
So, I tried the deferred approach [1] like this:
@colander.deferred
def deferred_choices_widget(node, kw):
choices = kw.get('choices')
return SelectWidget(values=choices)
@colander.deferred
def deferred_default(node, kw):
return kw['request'].POST.get('department')
class MySchema(colander.MappingSchema):
department = colander.SchemaNode(
colander.String(),
default=deferred_default,
widget=deferred_choices_widget,
)
I noticed that the request was not in 'kw' so I binded it to the schema:
schema = schema.bind(choices=departments,
default=default,
request=self.request)
Now I see the value into deferred_default call and I can get it using
`kw['request'].POST.get('department')` but there is no way to get it
into the form on reload after submit.
I can't find any meaningful step in the docs... what am I missing?
Versions: colander-0.9.8-py2.7, deform-0.9.5-py2.7, pyramid-1.3.3-py2.7
Thanks,
