我继承了一个使用Python 3.4构建的网站，Django 1.10带有一个MySQL数据库，除了一些旧的，未使用的遗留测试之外，它没有进行任何测试。我已经开始编写测试但在尝试运行manage.py test时遇到错误（在引发异常之前删除旧数据库大约需要5分钟）

the test database: (1007, "Can't create database 'test_rmpublic';

我查看了所有迁移文件，但看不到对establish_id的任何引用。认为它可能是旧的test_db的一个问题，我使用this问题中描述的hacky但接受的答案来使用sqlite3作为测试数据库，并得到一个新的错误：

为臃肿的堆栈痕迹道歉。任何帮助都会很棒。
