SQLAlchemy.all() 在使用 filter_by() 调用时不返回全部

Question

so whenever i Order.query.all() the results returned are complete, but when Order.query.filter_by(id=current_user.id).all() I only get one result back.

DB model setup:

class User(db.Model, UserMixin):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(30), nullable = False)
    email = db.Column(db.String(60), unique = True, nullable = False)
    password = db.Column(db.String(60), nullable = False)
    phone = db.Column(db.Integer, nullable = False)
    country = db.Column(db.String(30), nullable = False)
    city = db.Column(db.String(30), nullable = False)
    address = db.Column(db.String(350), nullable = False)
    kaftl = db.Column(db.String(30), nullable = False)
    order = db.relationship('Order', backref='buyer', lazy=True) 

class Order(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    date = db.Column(db.DateTime, nullable = False, default=datetime.utcnow)
    order = db.Column(db.Text, nullable = False)
    kaftl = db.Column(db.Integer, nullable = False)
    price = db.Column(db.Integer, nullable = False)
    user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)

HTML just in case it's useful:

{% for order in orders %}
       {{ order.price }}
       {{ order.order }}

   {% endfor %}

I think instead of id, you should use user_id as;

Order.query.filter_by(user_id=current_user.id).all()

Because id is unique for each object and when you call that code, it actually returns you the order with id= current_user.id.
