【中文标题】异常值：没有这样的表：vacancy_list_advuser

【英文标题】：Exception Value: no such table: vacancy_list_advuser

【发布时间】：2020-03-03 09:53:27

【问题描述】：

我为注册添加了用户类AdvUser 当我想登录或注册，或创建超级用户时，我收到错误：

文件“/home/alex/dev/python/django/junjob/myvenv/lib/python3.5/site-packages/django/db/backends/sqlite3/base.py”，第305行，在执行 返回 Database.Cursor.execute(self, query, params) django.db.utils.OperationalError：没有这样的表：vacancy_list_advuser

我做了什么

已检查AUTH_USER_MODEL = 'vacancy_list.AdvUser' # <app_name.model_name> 删除 vacancy_list/migrations 中的所有迁移，然后进行 makemigrations 和迁移 python manage.py migrate --run-syncdb

我应该怎么做才能解决问题？

【参考方案1】：

python manage.py migrate --fake APPNAME zero

然后运行迁移脚本

python manage.py migrate 

希望这会有所帮助！

【讨论】：

谢谢，但我有错误 1. 我删除了迁移 0001_initial.py 和 pycache 2. python manage.py makemigrations 3. python manage.py migrate --fake vacancy_list零 4. python manage.py migrate 在最后一个命令之后我有 django.db.utils.OperationalError: table "vacancy_list_company" already exists

"Company" -- 是我在models.py中的类

【参考方案2】：

According to this answer.您可能需要降级您的 SQLite 版本。我遇到的一个常见问题。
