In Django template, you can make methed call. So you can pass the
auther object to the template, then
{% for book in auther.books.all %}
{% for section in book.sections.all %}
{% end for %}
{% endfor %}
The ordering is using the definition in the Model Meta class.
auther.books and book.sections is my assumption for your FK related
names.
If you want to change the ordering, maybe a template tag is more
suitable for your purpose.
And about Form, I'm not clear what you want? A whole page with forms
for authors, books and sections? If so, you can have a look at
formset, specially the inlineformset. (http://docs.djangoproject.com/
en/dev/topics/forms/modelforms/#inline-formsets) If you just want to
get a simple form for inline editing in the author-book-section view
page, using js to generate it is my only choice
