The tool you're looking for here is the prefix argument to the form classes. You'll need to override some view methods like get_form and potentially get_form_class because class based views aren't designed to take more than one form type by default. You may also need to override the post method on the views to load the data from the post request into the forms.
The prefix argument means that the form data sent to your django app will be "namespaced" so the form class will only load in the post data it needs from the request.
Depending on how you're rendering your forms you may want to ensure the prefix is also rendered in the HTML input's name attribute.
