You can specify it upon form creation. Here is an example of how you
could use prefixes for multiple model forms:
In your views:
from django import newforms as forms
from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response
from yourproject.yourapp.models import ModelClass1, ModelClass2
def some_form_view(request):
form_classes = {ModelClass1: None, ModelClass2: None}
for model in form_classes:
form_classes[model] = forms.form_for_model(model)
form_objects = {}
if request.method == 'POST':
prefix = 0
forms_are_valid = True
for model, form_class in form_classes.iteritems():
form_objects[model] = form_class(request.POST, prefix='f' +
str(prefix))
forms_are_valid = forms_are_valid and
form_objects[model].is_valid()
prefix += 1
if forms_are_valid:
for model, form in form_objects.iteritems():
form.save()
return HttpResponseRedirect('/some/url')
else:
prefix = 0
for model, form_class in form_classes.iteritems():
form_objects[model] = form_class(prefix='f' + str(prefix))
return render_to_response('blah.html', {'forms':
form_objects.values()})
In your template:
<form action="." method="post">
{% for form in forms %}
{{ form.as_p }}
{% endfor %}
<div class="submit"><input type="submit" value="Submit"></div>
</form>
