While refs #34125 focused on the SQL correctness of slicing of union of potentially empty queries it missed an optimization opportunity to avoid performing a query at all when all queries are empty. Thanks Lucidiot for the report. |

====== Django ====== Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Thanks for checking it out. All documentation is in the "``docs``" directory and online at https://docs.djangoproject.com/en/stable/. If you're just getting started, here's how we recommend you read the docs: * First, read ``docs/intro/install.txt`` for instructions on installing Django. * Next, work through the tutorials in order (``docs/intro/tutorial01.txt``, ``docs/intro/tutorial02.txt``, etc.). * If you want to set up an actual deployment server, read ``docs/howto/deployment/index.txt`` for instructions. * You'll probably want to read through the topical guides (in ``docs/topics``) next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific problems, and check out the reference (``docs/ref``) for gory details. * See ``docs/README`` for instructions on building an HTML version of the docs. Docs are updated rigorously. If you find any problems in the docs, or think they should be clarified in any way, please take 30 seconds to fill out a ticket here: https://code.djangoproject.com/newticket To get more help: * Join the ``#django`` channel on ``irc.libera.chat``. Lots of helpful people hang out there. `Webchat is available <https://web.libera.chat/#django>`_. * Join the django-users mailing list, or read the archives, at https://groups.google.com/group/django-users. * Join the `Django Discord community <https://discord.gg/xcRH6mN4fa>`_. * Join the community on the `Django Forum <https://forum.djangoproject.com/>`_. To contribute to Django: * Check out https://docs.djangoproject.com/en/dev/internals/contributing/ for information about getting involved. To run Django's test suite: * Follow the instructions in the "Unit tests" section of ``docs/internals/contributing/writing-code/unit-tests.txt``, published online at https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/unit-tests/#running-the-unit-tests Supporting the Development of Django ==================================== Django's development depends on your contributions.
