In my forms.py app, I have the following lines:

from flask_wtf import FlaskForm

from wtforms import SelectField, StringField, SubmitField, TextAreaField, PasswordField, BooleanField

from wtforms.validators import DataRequired

from flask_login import current_user



class LogForm(FlaskForm):

    #game, title, log, submit

    game = SelectField(u'Select Game', default='', coerce=str, choices=[(game.game_name, game.game_name) for game in current_user.games])

    game.choices = [(game.game_name, game.game_name) for game in current_user.games]

    title = StringField('Title', validators=[DataRequired()])

    log = TextAreaField('Game log', validators=[DataRequired()])

    submit = SubmitField('Update')



class RegisterForm(FlaskForm):

    username = StringField('Username', validators=[DataRequired()])

    email = StringField('Email', validators=[DataRequired()])

    password = PasswordField('Password', validators=[DataRequired()])



class LoginForm(FlaskForm):

    username = StringField('Username', validators=[DataRequired()])

    password = PasswordField('Password', validators=[DataRequired()])

    remember_me = BooleanField("Remember me")

    submit = SubmitField("Sign in")

When I run my code, I get the following error:

>>> from app import db

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

    return getattr(self._get_current_object(), name)

AttributeError: 'NoneType' object has no attribute 'id'

For reference, below are the relevant parts of the models.py file

from app import db

from datetime import datetime

from werkzeug.security import generate_password_hash, check_password_hash

from flask_login import UserMixin

from app import login 



@login.user_loader

def load_user(id):

    return User.query.get(int(id))



class User(UserMixin, db.Model):

    __tablename__ = "User"

    id = db.Column(db.Integer, primary_key=True)

    username = db.Column(db.String(64))

    hashed_password = db.Column(db.String(128))

    games = db.relationship('Game', backref='creator', lazy=True)



    def set_password(self, password):

        self.hashed_password = generate_password_hash(password)



    def check_password(self, password):

        return check_password_hash(self.hashed_password, password)



    def __repr__(self):

        return f'<User {self.username}>'

I've tried to put an if statement containing something like if current_user is None to the LogForm form, but it still won't work. Why does this happen? Help!

Edit: Adding an is_authenticated check before the form statement returns AttributeError: 'NoneType' object has no attribute 'is_authenticated'
