Re: MultiValueField Question
As above, I have this working now. Any suggestions on wrapping individual items in items from a multivaluefield in tds?

Re: MultiValueField Question
OK, so I've somewhat answered my own question here and gotten things
figured out.
I do, however, have another question.
What would be the proper/clean way to do inline editing with newforms?
In the end I did some extremely hackish things to get the multiwidget/
multivaluefields to render with each item in a row being in a separate
.
Basically I want to have tables like the following:
Name AttendingEvent1AttendingEvent2
AttendingEvent3
Name1
X
X
Name2 X
etc..
This table is made up of model instances that are tied via foreign key
to a parent group, so this means the form also ends up with items that
don't belong in a tabular format.
What should I be subclassing to do this? I don't want everything in
each row in a single or , this way it's difficult to associate
the fields with meaning.
Might it make sense to have a different way to display fields in
inline editing mode with labels in a header row, and then instances of
a model showing up in the following rows?
I won't post any of the hacky code I just put together because it is
rather evil, and I'd like to replace it :-) It does, however, work
quite well!

MultiValueField Question
Hi -
I've been attempting to put together a website to use for keeping
track of information for a wedding, and I'm wanting to use multiple
inline lists of invitees within each group that has been sent an
invite. Basically I want something like the admin interface where one
can do tabular inline editing. I'm also new to both python and
django.
I've tried following along with this: http://www.hoboes.com/Mimsy/?ART=607
I've also read what is on the list here regarding using
MultiValueFields, and I can get things working with a fixed number of
elements in a MultiValueField, but things are breaking down for me
with greater numbers. I'm getting the following error: 'NoneType'
object is unsubscriptable
This, I presume has to do with the way that I'm doing/not doing
compress/decompress on the data for the Fields and Widgets, but I'm
lost as to what I need to do within these functions to give valid
output. Here's a portion of the code I'm using. Any suggestions as
to why when I do the following:
a = weddingsite.register.views.GroupForm()
print a
I get:
