Yes, you'd do it this way. Forms (and formsets too) take a prefix
argument which you can use to differentiate between the forms.
I think you do not want to validate and save them individually though
(I'm sorry if I did not understand you), you probably do not want to
save anything until all forms have passed validation:
if request.method == 'POST':
# initialize forms with request.POST and prefix
if form1.is_valid() and form2.is_valid() and form3.is_valid():
# save the data from the individual forms
else:
# ....
return render_to_response('template.html', {'form1': form, 'form2':
form, 'form3': form})

Then you'll want to look into formsets, and use their prefix parameter
too to make sure that the field names of different formsets don't
clash.
