+Using a model formset in a view
+-------------------------------
+
+Model formsets are very similar to formsets. Lets say we want to present a
+formset to a user to edit ``Author`` model instances::
+
+    def manage_authors(request):
+        AuthorFormSet = modelformset_factory(Author)
+        if request.POST == 'POST':
+            formset = AuthorFormSet(request.POST, request.FILES)
+            if formset.is_valid():
+                formset.save()
+                # do something.
+        else:
+            formset = AuthorFormSet()
+        render_to_response("manage_authors.html", {
+            "formset": formset,
+        })
+
+As you can see the view is not drastically different than how to use a formset
+in a view. The only difference is that we call ``formset.save()`` to save the
+data into the database. This was describe above in :ref:`ref-saving-objects-in-the-formset`.

 Using ``inlineformset_factory``
