在应用程序上下文之外工作 - Flask

也许您需要在应用程序上下文中调用您的函数:

with app.app_context():
  # call your method here

Juan Pablo S.. 14

来自Flask的源代码flask/globals.py:

_app_ctx_err_msg = '''\
Working outside of application context.

This typically means that you attempted to use functionality that needed
to interface with the current application object in a way.  To solve
this set up an application context with app.app_context().  See the
documentation for more information.\
'''

在文档之后,您可以看到您需要flask.current_app指出您的应用程序,而目前却没有.

在Flask初始化之前,您可能正在调用数据库函数.我的猜测是你的app对象还没有用Flask构造函数创建.
