As I was unable to find good examples to render a Form with two or more inlineformsets. Therefor I have posted this to Django snippets. This code is little different from another snippet with a Form with one InlineFormSet (the prefixes are necessary in this situation).

The example shows a person's data together with two inline formsets (phonenumbers and addresses) for a person.

You can add, update and delete from this form.

Hello,

First, thanks a lot for this snippet, it was very usefull for me !

Then I have a comment about the case of a new person (recipe for me ^^), the "inline_model"formset.save() function need to know the id of the new person (for the foreign key) and they didn't have it. so I had to specify it manually.

Did you enconter this trouble ? and do you have a nicest solution ?

Thanks again
