It's only been 12 hours since your first post; sometimes it will take a little longer than that for somebody to answer your question. > > Let's say I have a form called add-new-group.html that looks like > > this: > > > > Group Name: __________________ > > > > Member 1 --> Name:___________ Age: ____ > > Member 2 --> Name:___________ Age: ____ > > Member 3 --> Name:___________ Age: ____ > > > > So when the form is saved, it needs to save the new group to the > > 'group' table, and it needs to save up to three new members to the > > 'member' table. > > > > How in the world can I do this? There are two ways that should work. Which one you choose depends on how your models are set up and what you feel more comfortable with, so experiment with both and see which works. The first way is to create a custom manipulator (see [1]) that contains fields for the group name and the three member names and ages (e.g. name1, age1, name2, age2, etc). Then create a normal form as in the forms documentation. After checking for errors and calling the html2python() method, you then pull out the fields and use them to create the new objects (using the model/database API as in [2]). You will be able to access the fields as manipulator.name1, manipulator.group, etc. [1] http://www.djangoproject.com/documentation/forms/#custom-forms-and-manipulators [2] http://www.djangoproject.com/documentation/db_api/#creating-objects This method has a limitation that the number 3 is hard-coded into it. You could work around that with a bit of reading of the Django source and using django.forms.InlineObjectCollection, I suspect, but that's probably more work than you want to do at this point. The second method works if the members can be edited inline with the group model. Then you can use the standard AddManipulator for the Group model and the create_update generic view form ([3]). I have given a bit of an outline how to do that in [4]. [3] http://www.djangoproject.com/documentation/generic_views/#create-update-delete-generic-views [4] http://www.pointy-stick.com/blog/2006/07/03/django-tips-forms-multiple-inline-objects/ Hopefully this gives you something to work with. Basically, though, any time you are wondering how to do something with a form that is more than just working with a single model, think of using custom manipulators.
