The get_(local|foreign)_related_value methods of GenericRelation must be reversed because it defines (from|to)_fields and associated related_fields in the reversed order as it's effectively a reverse GenericForeignKey itself. The related value methods must also account for the fact that referenced primary key values might be stored as a string on the model defining the GenericForeignKey but as integer on the model defining the GenericRelation. This is achieved by calling the to_python method of the involved content type in get_foreign_related_value just like GenericRelatedObjectManager does. Lastly reverse many-to-one manager's prefetch_related_querysets should use set_cached_value instead of direct attribute assignment as direct assignment might are disallowed on ReverseManyToOneDescriptor descriptors. This is likely something that was missed in f5233dc (refs #32511) when the is_cached guard was added. Thanks 1xinghuan for the report. Backport of 198b30168d4e94af42e0dc7967bd3259b5c5790b from main.
====== 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://chat.djangoproject.com>`_. * 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.
