How can I disable ExtDeprecationWarning for external libs in flask

Question

When I run my script, I get this output:

/app/venv/lib/python2.7/site-packages/flask/exthook.py:71: ExtDeprecationWarning: Importing flask.ext.sqlalchemy is          


        

Answer 1

As of Flask 1.0, flask.ext does not exist. Packages that haven't fixed these imports will not work.

First, you should care about this because the packages you're using aren't up to date. Report a bug that they should switch to using direct import names, such as flask_sqlalchemy, rather than the flask.ext import hook.

Add a warnings.simplefilter line to filter out these warnings. You can place it wherever you're configuring your application, before performing any imports that would raise the warning.

import warnings
from flask.exthook import ExtDeprecationWarning

warnings.simplefilter('ignore', ExtDeprecationWarning)
