大家早上好。这是我的问题：

我是 Node.js 的新手，我决定尝试 Geddy 框架，因为它看起来非常强大。所以，我正在关注本教程。当我向 ToDo 模型添加一些验证时，它会抛出一个错误并且我无法启动服务器。

欢迎任何帮助。

这里的代码：

var ToDo = function () {
    this.defineProperties({
        tittle: {type: 'string', required: true},
        status: {type: 'string', required:true},
    });

    this.validatesPresent('title');
    this.validatesLength('title', {min: 5});

    this.validatesWithFunction('status', function (status) {
        return status == 'open' || status == 'done';
    }, {message: "Status must be 'open' or 'done.'"});

};

ToDo = geddy.model.register('ToDo', ToDo);

这是控制台输出

你有一个双“t”。 

this.defineProperties({
    tittle: {type: 'string', required: true}, //this should be title
    status: {type: 'string', required:true}, // and this comma should be deleted
});
