I’m not able to import Flask-WTF TextField and BooleanField

I’m using virtualenv to set up a new project. I installed a lot of things using virtualenv pip from the script folder like below:

flaskscriptspip install Flask-WTF

I have no other packages installed in the global python folder. My code looks like this:

# Importing TextField and BooleanField is not working...
from flask.ext.wtf import Form, TextField, BooleanField
from flask.ext.wtf import Required


class LoginForm(Form):
    openid = TextField('openid', validators=[Required()])
    remember_me = BooleanField('remember_me', default=False)

and other packages are found like sqlalchemy also installed only in the virtual environment.

The error I get is:

(flask) D:Developmentgrading>flaskScriptspython.exe restserver.py Traceback (most recent call last):
File "restserver.py", line 1, in <module> from app import app
File "D:Developmentgradingapp__init__.py", line 12, in <module> from forms import LoginForm
File "D:Developmentgradingappforms.py", line 1, in <module> from flask.ext.wtf import Form, TextField, BooleanField
File "D:Developmentgradingflasklibsite-packagesflaskexthook.py", line 87, in load_module
raise ImportError('No module named %s' % fullname) ImportError: No module named flask.ext.wtf.TextField

Form is found but not TextField and BooleanField. What is the problem here?

Update I just looked through some of the Flask-WTF code and found this:

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

Am I using examples from an older version or something?

Answer

From version 0.9.0, Flask-WTF will not import anything from wtforms, you need to import fields from wtforms.

You need to import them from wtforms (note that according to docs import statement was changed):

from flask_wtf import Form

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