If you could slightly rename your submission fields, there is indeed an
easier way to do this. I'm assuming you are using Django's "newforms"
package to create a form class of some kind. The "prefix" attribute that
you can optionally pass to a form's __init__ method can be used to tweak
the names expected by a form's elements.
Also, since you can happily pass extra information to a form (it will
just ignore it), you will end up with something like the following:
# Assume MasterForm and DetailForm are your form classes
def my_view(request, ...):
master = MasterForm(request.POST)
detail_forms = []
for i in range(XX): # work out XX somehow
detail_forms.append(DetailForm(request.POST,
prefix=str(i))
# ... (now check is_valid(), etc, as per normal)
To see how the form element should be named here, have a look at [1],
for example. That's part of the test suite and shows the default naming.
You could also override the add_prefix() in your form so that it returns
something in the format you're expecting from the form submission.

This might all take more than just a couple of minutes to master, since
you said you were just starting out with Django and Python. Like
anything new, doing advanced stuff will require a bit of patience and
experimentation, so just try things out and you'll gradually close in on
a solution.
