Prior to this change foreign key constraint references could be left pointing at tables dropped during operations simulating unsupported table alterations because of an unexpected failure to disable foreign key constraint checks. SQLite3 does not allow disabling such checks while in a transaction so they must be disabled beforehand. Thanks ezaquarii for the report and Carlton and Tim for the review.

Django 2.1.5 release notes
|
|
==========================
|
|
|
|
*Expected January 1, 2019*
|
|
|
|
|
|
Django 2.1.5 fixes several bugs in 2.1.4.
|
|
|
|
Bugfixes
|
|
========
|
|
|
|
* Fixed compatibility with mysqlclient 1.3.14 (:ticket:`30013`).
|
|
|
|
* Fixed a schema corruption issue on SQLite 3.26+. You might have to drop and
|
|
rebuild your SQLite database if you applied a migration while using an older
|
|
version of Django with SQLite 3.26 or later (:ticket:`29182`).
|
|
|
|
* Prevented SQLite schema alterations while foreign key checks are enabled to
|
|
avoid the possibility of schema corruption (:ticket:`30023`).
