在Django中迁移并创建超级用户后，“没有这样的表：accounts_user”

标签： python django django-models django-rest-framework django-rest-auth

我正在使用 Django-rest-auth 创建rest API，并且在名为accounts的应用程序中有一个自定义用户模型。问题是进行迁移后，当我尝试在控制台中创建超级用户后，在电子邮件字段中输入电子邮件后，

我遇到很多错误，告诉我"no such table: accounts_user"

我的设置。py

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    objects = UserManager()

    def __str__(self):
        return self.email

我遇到的错误：

我尝试删除db.sqlite3并重新运行迁移，但仍然是相同的错误。

我也尝试运行"python manage.py migrate --run-syncdb"，该方法可以正常工作，但是后来发现，当我尝试重置密码时，出现了一个错误，提示没有这样的表"accounts_user.fullname"。

运行python manage.py showmigrations，我得到：

答案 0 :(得分：0)

请尝试再次使用makemigrations。看起来您已经对模型进行了一些更改，但是这些更改未反映在迁移文件中。 https://docs.djangoproject.com/en/2.2/topics/migrations/#workflow
