推荐答案
OrdersProduct currentProduct = {populate from database};
...
currentProduct = modifiedProduct;
这很不好-尤其是如果您要让用户访问关键字段并对其进行修改！！！
还请确保您自己不在任何地方修改"ID"字段！
That is bad -- especially if you are letting your user get access to the key field and modifying it!!!
Also make certain you''re not modifying the field ''ID'' anywhere yourself!
