在admin中保存新模型时,表"django_admin_log"上的插入或更新违反了外键约束

在admin中保存模型的新实例时,我在回溯中获得以下IntegrityError:

完全相同的代码在另一台机器上完美运行.

看起来Django用户表以某种方式变得陈旧并包含过时的主键.不幸的是,运行./manage.py migrate似乎没有解决任何问题,但在旧的Django trac票证的帮助下,我能够弄清楚如何轻松解决这个问题(警告,你将丢失你的管理日志).

./manage.py migrate admin 0001
echo "DROP TABLE django_admin_log;" | ./manage.py dbshell
./manage.py sqlmigrate admin 0001 | python manage.py dbshell
./manage.py migrate admin

我确信我可以在PostgreSQL中运行更新以达到同样的效果,但我没有任何我担心保留的数据.
