Root Cause

Trying to call a method that does not exist on the Flask app object, often due to typo or wrong object.

generic

中文

尝试调用Flask应用对象上不存在的方法，通常是由于拼写错误或对象错误。

Workarounds

  1. 90% success Check Flask documentation for correct method 
    Use app.route() instead of app.get() for defining routes.
  2. 85% success Use dir() to list available attributes 
    print(dir(app))

Dead Ends

Common approaches that don't work:

  1. Assuming Flask has all common methods 50% fail

    Flask has specific methods; not all are available.

  2. Confusing Flask with other frameworks 80% fail

    Methods like 'get' or 'post' are not Flask methods.
