Correct Case Study: The final price and amount fields display the results after the summation of grouping and sorting

from sqlalchemy import func
from app.models.base import db

# 分组排序后最终显示price和amount字段求和的结果
buy_order = db.session.query(BuyOrder.price, func.sum(BuyOrder.amount)).filter_by(order_status=1).group_by(BuyOrder.price).order_by(BuyOrder.price.desc()).all()
