Fix the variable name in backref:
Right now it says:
user = db.relationship("User", backref="user")
It should be:
user = db.relationship("User", backref="userbook")
full example: `class UserBook(db.Model): """ Books that the user has read and rated. """
# This is a middle table __tablename__ = "user_books" user_book_id = db.Column(db.Integer, autoincrement=True, primary_key=True) user_id = db.Column(db.Integer, db.ForeignKey("users.user_id"), nullable=False) book_id = db.Column(db.Integer, db.ForeignKey("books.book_id"), nullable=False) book_read = db.Column(db.Boolean, default=False, nullable=False) rating = db.Column(db.Integer, nullable=True) updated_at = db.Column(db.DateTime, nullable=True) book = db.relationship("Book", backref="user_books") user = db.relationship("User", backref="user") def __repr__(self): """ Provide helpful representation of ratings when printed""" return "<Book book_id=%s user_id=%s rating=%s>" % (self.book_id, self.user_id, self.rating)`
