从 Flask SQLAlchemy 向数据库添加数据时出现问题：未找到应用程序。在视图函数中工作或推送

我有个问题。我用视频截图进行了描述，以使其更清晰：https ://www.loom.com/share/433602541e5144588a189a44085283f1

为了捕捉错误，我尝试在控制台中向数据库添加数据：

from app import db
from app.base.models import Users
admin = Users(email='admin@example.com', psw='12345678')
db.session.add(admin)

Traceback (most recent call last):
  File "E:\DjangoEnv\flask-dashboard-volt\lib\site-packages\sqlalchemy\util\_collections.py", line 1020, in __call__
    return self.registry[key]
KeyError: <greenlet.greenlet object at 0x0000028AC99851A8 (otid=0x0000028AC6D70318) current active started main>
During handling of the above exception, another exception occurred:

    self.app = app = db.get_app()

'No application found. Either work inside a view function or push'

RuntimeError：未找到应用程序。在视图函数中工作或推送应用程序上下文。请参阅http://flask-sqlalchemy.pocoo.org/contexts/。

这就是错误。我不知道如何解决这个问题。

代码本身在这里的存储库中。
