Error loggining in [Class '<class 'app.models.User'>' has no field 'username'."]

[OneVoltTen]

After submitting user login it displays the following error:

[Roman Hosek]

I've got same error.
Add username field to the model:
models.py:28
username = db.Column(db.Unicode(50), nullable=False, server_default=u'')
and fill it in manage_commands.py:49
user = User(email=email, first_name=first_name, username=first_name,
(you may need to keep username separated from first name, I just used first name for simplicity)

then delete app.sqlite from the root and recreate DB with python manage.py init_db
Now you will be able to login with default Admin/Password1

Hope that help you a little
