I'm a bit confused, I'm hoping someone can point in the right direction. I
would like to be left with a data structure similar to the following:
data = {
'ids': [ 1, 2, 8, 14, 15]
}
Assuming I build my form options with the following:
opts = [ x, "Option %d" % x for x in range(50) ]
Now I build a schema and intend to use a checkbox_choice widget:
class profSchema(colander.MappingSchema):
ids = colander.SchemaNode(colander.Seq(),
widget=deform.widget.CheckboxChoiceWidget(
values=opts,
),
)
This works up until the form is submitted, and then it fails with "IndexError:
list index out of range" if any checkbox is selected. I have not been able to
get it to work at all with colander.Seq(), perhaps I don't know how to use it
properly. Meanwhile, it also allows for blank lists even though it is a
required field. I don't understand this. As far as I can tell the above
correct but refuses to work.
I switched to use deform.Set(). This works well. Except for the fact that the
data returned is all in string form:
data = {
'ids': set([u'1', u'2', u'5'])
}
How do I require it to be ints, not strings?
In short can someone point me in the right direction on how to define a schema
that has a field of a list of integers.
Thanks in advance for any help.
Cheers,
Ari
