+``update_or_create(**kwargs)``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**New in Django development version**
+
+A convenience method for looking up an object with the given kwargs, and then
+either updating the values of the object if one is found or creating an
+object if one was not found.
+
+This method calls ``get_or_create()`` behind the scenes, and similarly
+returns a tuple of ``(object, created)``, where``object`` is the updated or
+created object and ``created`` is a boolean specifying whether a new object
+was created.
+
+This is meant as a shortcut to the following type of code::
+
+    obj, created = Person.objects.get_or_create(first_name='John', last_name='Lennon',
+                       defaults={'birthday': date(1940, 10, 9)})
+    if not created:
+	    obj.update('birthday'=date(1940, 10, 9))
+
+This pattern gets quite unwieldy as the number of fields in a model goes up.
+The above example can be rewritten using ``update_or_create()`` like so::
+
+    obj, created = Person.objects.update_or_create(first_name='John', last_name='Lennon',
+                       defaults={'birthday': date(1940, 10, 9)})
+
+Any keyword arguments passed to ``update_or_create()`` will be used in a
+call to ``get_or_create()``. If ``get_or_create()`` creates an object, then
+nothing needs to be done by ``update_or_create()`` and a tuple of the created
+object and ``True`` is returned. If, on the other hand, ``get_or_create()``
+does not create a new object, then ``update_or_create()`` will update the
+object with the values passed in the ``defaults`` parameter and a tuple of
+the updated object and ``True`` is returned.
+
+The ``defaults`` parameter should be a dict of attribute-value pairs that
+you want to update. If ``defaults`` is empty or not specified, then
+``update_or_create()`` will act exactly like ``get_or_create()`` since there
+would be nothing to update.
+
+As with ``get_or_create()``, if you need to use ``update_or_create()`` in a
+view, please make sure to use it only in ``POST`` requests unless you have a
+good reason not to. ``GET`` requests shouldn't have any effect on data; use
+``POST`` whenever a request to a page has a side effect on your data. For
+more, see `Safe methods`_ in the HTTP spec.
