Django：尝试从管理员创建用户时出现OperationalError [英] Django: OperationalError when I try to create user from admin

问题描述

我使用MySQL的Django 1.10，每次输入admin并尝试使用户时都会出现此错误：

I have Django 1.10 with MySQL, every time I enter admin and I try to make a user I get this error:

问题是我可以创建任何其他模型，如果我从命令行创建超级用户，则可以编辑该用户，但是当我按添加用户时，我得到这个错误。我尝试删除数据库并再次创建两次。

The thing is I can create any other model and if I create a super user from command line I can edit that user but when I press "add user" I get this error. I tried deleting the database and making it again twice.

这是我的settings.py：

推荐答案

对于我来说，我发现根本原因是 MySQL-Python 数据库驱动程序，解决方法是将其他MySQL驱动程序用于Python（例如 mysqlclient ）。

In my case, I've found out that the root cause is the MySQL-Python database driver and the fix is to use other MySQL drivers for Python (e.g. mysqlclient).

$ pip uninstall MySQL-Python
$ pip install mysqlclient

MySQL-python 原来很旧（最后一次提交是在7年前）。 mysqlclient 是它的现代版本，具有许多改进和错误修复。

MySQL-python turned out to be very old (last commit was 7 years ago). mysqlclient is the modern version of it, with lots of improvements and bug fixes.
