使用复合时，我在使用validatesPresenceOf时出现了更新错误

Question

我正在用复合和mongodb创建一个应用程序。复合使用jugglingdb和jugglingdb-mongodb连接到mongodb。

我用化合物的脚手架为客户生成了一个crud。然后，我将Client.validatesPresenceOf('name');添加到app/model/client.js中。

module.exports = function (compound, Client) {
  Client.validatesPresenceOf('name');
};

在创建时，它可以工作，但是在更新时它会失败。

我还尝试将验证添加到db/schema.js，但得到了相同的错误。

这就是我所犯的错误
