Root Cause

Attempting to access Flask features like current_app or url_for outside of a request or app context.

generic

中文

在请求或应用程序上下文之外尝试访问 Flask 功能，如 current_app 或 url_for。

Workarounds

  1. 100% success 
    Use with app.app_context(): before accessing current_app or url_for
  2. 95% success 
    If in a CLI command, use app = create_app() and then with app.app_context():

Dead Ends

Common approaches that don't work:

  1. 80% fail

    You need to push an app context manually.

  2. 100% fail

    current_app is a proxy that requires an active context.
