## Description
|
||
<section id='description'> <code>0</code>最新版本的mongoose具有简化文档更新的方法。一些更高级的功能（即前/后挂钩，验证）与此方法的行为不同，因此Classic方法在许多情况下仍然有用。在按Id搜索时可以使用findByIdAndUpdate（）。 <code>0</code>按名称查找人员并将其年龄设置为20.使用函数参数personName作为搜索关键字。 <code>0</code>提示：我们希望您返回更新的文档。为此，您需要将选项文档{new：true}作为findOneAndUpdate（）的第三个参数传递。默认情况下，这些方法返回未修改的对象。
