+13. Adding hooks before/after saving and deleting
+
+Django provides hooks for executing arbitrary code around ``save()`` and
+``delete()``. Just add any of the following methods to your model:
+
+    * ``_pre_save()`` is called before an object is saved.
+    * ``_post_save()`` is called after an object is saved.
+    * ``_pre_delete()`` is called before an object is deleted.
+    * ``_post_delete()`` is called after an object is deleted.
