reverse_ordering() Returns self with any modifications required to reverse the sort order within an order_by call. As an example, an expression implementing NULLS LAST would change its value to be NULLS FIRST. Modifications are only required for expressions that implement sort order like OrderBy. This method is called when reverse() is called on a queryset.

patch(path, data='', content_type='application/octet-stream', follow=False, secure=False, **extra) [source] Makes a PATCH request on the provided path and returns a Response object. Useful for testing RESTful interfaces. The follow, secure and extra arguments act the same as for Client.get().

Unlike the other request methods, data is not provided as a keyword parameter in order to comply with RFC 7231#section-4.3.8, which mandates that TRACE requests must not have a body. The follow, secure, and extra arguments act the same as for Client.get().
