Django doesn't support that mode of access (slicing from the end), because it's not possible to do it efficiently in SQL. Also, note that reverse() should generally only be called on a QuerySet which has a defined ordering (e.g., when querying against a model which defines a default ordering, or when using order_by()). If no such ordering is defined for a given QuerySet, calling reverse. Making queries¶. Once you've created your data models, Django automatically gives you a database-abstraction API that lets you create, retrieve, update and delete objects.This document explains how to use this API. Refer to the data model reference for full details of all the various model lookup options.. Throughout this guide (and in the reference), we'll refer to the following models. Herzlich willkommen!

#29493 (Block strings from being passed to `__in`) - Django

Fixed __in lookup on key transforms for JSONField with MariaDB, MySQL, Oracle, and SQLite . Fixed a regression in Django 3.1 that caused permission errors in CommonPasswordValidator and settings.py generated by the startproject command, when user didn't have permissions to all intermediate directories in a Django installation path ( #31912 ) django-mysql customizes the __in lookup by encoding the rhs and CAST-ing it to JSON. I think it won't work on MariaDB though, because we can't do casting to JSON. There may be other ways to do it, but I haven't got an idea. Same with SQLite and Oracle Habe ich Tabellen namens 'has_location' und 'Orten'. 'has_location' hat user_has und location_id und seine eigenen id die von django selbst. 'Standorten

  1. Long list in queryset's __in lookup Hi everyone, I am having an issue with the queryset's __in lookup. The story is that we need to filter within a very long list. E.g. users = User. objects. filter (id__in = long_list_uids). filter (** logic_conditions). Since the long_list_uids is really long (Around 20k items), it will be ineffective to pass the list to the DB layer. And there is no way to.
  2. Removing the __in required replacing these calculations with a lot more server code, which included using a Postgres materialized view.

(No poetry intended. ) My point remains that __in operations.
