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:
flask\scripts\pip 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:\Development\grading>flask\Scripts\python.exe restserver.py Traceback (most recent call last):
File "restserver.py", line 1, in <module> from app import app
File "D:\Development\grading\app\__init__.py", line 12, in <module> from forms import LoginForm
File "D:\Development\grading\app\forms.py", line 1, in <module> from flask.ext.wtf import Form, TextField, BooleanField
File "D:\Development\grading\flask\lib\site-packages\flask\exthook.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?
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
