ImportError при импорте форм фляжки WTF

Question

Я не вижу, где я ошибаюсь. У меня установлены последние формы WTF, но я все еще получаю эту ошибку.

Метод:

from flask.ext.wtf import Form 
from wtforms import PasswordField, validators, fields 
from wtforms.fields import TextField, BooleanField 
from wtforms.validators import Required, Email, EqualTo 

Результат:

Traceback (most recent call last):

flask_wtf wtforms

Answer 1

Согласно official quickstart, flask.ext.wtf должен быть flask_wtf.

Таким образом, вы должны импортировать его как:

from flask_wtf import FlaskForm 

По крайней мере, у меня есть, я установил с пип.

Answer 2

Похоже, вы установили только wtforms, не Flask-WTF расширение.

Чтобы установить Flask-WTF: pip install flask-wtf

Answer 3

Пожалуйста, используйте

from flask_wtf import Form 

from wtforms import TextField, BooleanField,IntegerField 
from wtforms.validators import Required 

Это был изменен с v0.8
