问题
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):
File "bin/runserver.py", line 2, in <module>

from flask.ext.wtf import Form, SelectField

raise ImportError('No module named %s' % fullname)
ImportError: No module named flask.ext.wtf.SelectField
Did SelectField is replace by a new method?

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
