Flask: how to sort list by model fields?

Question

Flask

I have a simple model and a function to display model instances in an html template. The list is displayed.
models.py

class Datacener(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    number = db.Column(db.Integer)
    name = db.Column(db.String(64), index=True, unique=True)
    place = db.Column(db.String(64))
    capacity = db.Column(db.Integer, index=True)
    server = db.relationship('Server', backref='datacener', lazy=True)
    tier = db.Column(db.Integer)
    
    def __repr__(self):
        return '<Datacenter {}>'.format(self.name)

views.py

@app.route('/')
def index():
    datacenter = Datacener.query.all()   
    return render_template('index.html', title='Home', datacenter=datacenter)

I can't figure out how to sort by some model fields on this page. How to immediately display a sorted list, for example, according to the capacity field is clear:

datacenter = Datacener.query.order_by(Datacener.capacity)

And so that the user could sort?
