我是新手python编程

有些人可以帮助我

谢谢

Answer 1

您的sendEmails模块在顶层有一个查询：Site.objects.get_current()。在迁移有机会运行之前，在导入模块时运行。

您不得在此级别执行任何数据库操作;把它放进一个方法。

Answer 2

在您的INSTALLED_APPS和运行迁移命令

中添加django.contrib.sites

python manage.py makemigrations
python manage.py migrate

希望这有助于你

Answer 3

将"django.contrib.admin"中的INSTALLED_APPS更改为"django.contrib.admin.apps.SimpleAdminConfig"，然后运行makemigrations命令。之后，您可以还原更改。

Answer 4

在这种情况下，某些迁移仍未完成，因此请运行python manage.py migrate和python manage.py makemigrations app_name

Makemigrations错误：django.db.utils.OperationalError：没有这样的表
