You need formsets. A general introduction is here:
http://docs.djangoproject.com/en/1.2/topics/forms/formsets/
and a guide to building formsets based on models is here:
http://docs.djangoproject.com/en/1.2/topics/forms/modelforms/#id1

Sounds a lot like "tagging".  Have a look at this:

Even if its not exactly what you want, it may give you some ideas...

Creating and binding more than one model to a from

[thusjanthan]

Hi,

I have a Topic class I would like to create a form based on. BUT, I
want many of these objects so Topics. How do I obtain such a feature.

Suppose my form object is as follows:

class TopicForms(ModelForm):
class meta:
model = Topic
fields = ('topic_id','topic')

I want to display more than one of the topics that is associated to a
particular object. Suppose its a topic about obama and there are 10
topics. I want to display all 10 of these. and If they make a change
to one of them I would like to save that change on submission. I would
also like to provide additional blank topic fields for end users to
enter new topics about obama. Any help would be appreciated. I am a
little confused on the forms area of django.
