+Be aware that the ``update()`` method is converted directly to an SQL
+statement. It is a bulk operation for direct updates. It doesn't run any
+``save()`` methods on your models, or emit the ``pre_save`` or ``post_save``
+signals (which are a consequence of calling ``save()``). If you want to save
+every item in a ``QuerySet`` and make sure that the ``save()`` method is
+called on each instance, you don't need any special function to handle that.
+Just loop over them and call ``save()``:
+
+    for item in my_queryset:
+        item.save()
+
