I am getting this error and I am not sure what I am doing wrong. I created the form just like and example I got from the internet. I followed this example https://wtforms-alchemy.readthedocs.org/en/latest/introduction.html#quickstart
class User(db.Model):
__tablename__= 'users'
DRIVER = 'driver'
ADMIN = 'admin'
username = db.Column('username', db.String(80), primary_key=True)
_pw_hash = db.Column('pw_hash', db.String(128), nullable=False)
_pw_salt = db.Column('pw_salt', db.String(20), nullable=False)
first_name = db.Column('full_name', db.String(100), nullable=False)
last_name = db.Column('last_name', db.String(100), nullable=False)
email = db.Column('email', db.String(120))
phone = db.Column('phone', db.String(20))
#acct_type = db.Column('acct_type', db.Enum(DRIVER, ADMIN), nullable=False)
def check_pw(self, pw):
return self._pw_hash == util.pwhash(pw, self._pw_salt)
@property
def _pw_hash(self):
return self._pw_hash
@_pw_hash.setter
def password(self, pw):
self._pw_salt = util.salt(20)
self._pw_hash = util.pwhash(pw, self._pw_salt)
def __init__(self, un, pw, first, last, acct_type, email=None, phone=None):
self.username = un
self.password = pw
self.first_name = first
self.last_name = last
self.acct_type = acct_type
self.email = email
self.phone = phone
UserFrom = model_form(User, base_class=Form, exclude=['_pw_hash'])

You've mistakenly used the appengine
auto form, not the sqlalchemy one. Take a look at the path in the traceback: wtforms/ext/appengine/db.py
. You also seem to be confusing the sqlalchemy support built in to WTForms with the separate WTForms-Alchemy package.
If you want to use the built-in support:
from wtforms.ext.sqlalchemy.orm import model_form
UserForm = model_form(User, _exclude=['_pw_hash'])
If you want to use the separate WTForms-Alchemy package:
from wtforms_alchemy import ModelForm
class UserForm(ModelForm):
class Meta:
model = User
exclude = ['_pw_hash']
