No module named flask.ext.wtf.SelectField

Question

I found flask-jquery-ajax-example and I tried to run it with the latest library versions:

$ pip install flask flask-wtf wtforms
$ pip install -e ./

However, I got the ImportError: No module named flask.ext.wtf.SelectField while starting the scripts:

$ python bin/runserver.py
Traceback (most recent call last):

ImportError: No module named flask.ext.wtf.SelectField

Did SelectField is replace by a new method?

Answer 1

That tutorial hasn't been updated in about 2 years. Flask-WTF dropped support for field imports several versions ago. You need to import them directly from WTForms.

from wtforms import SelectField
