Javascript 节点orm2返回find（）结果

在我的配置文件模型中，我有以下方法：

// Check login and return object
checkLogin: function(username, password) {
        ProfileObj = Profile.find({username: username, password: password}).one(function(err, profile){
                         return profile;
                    });

        console.log(ProfileObj);
        return ProfileObj;
}

要调用此方法，我使用：

profile = req.models.profile();
ProfileObj = profile.checkLogin('test', 'test');

不幸的是，我没有得到我想要的对象，我得到的是模型，而不是实例。find（）回调中的“profile”变量是我想要的，但没有返回它。相反，ProfileObj是整个模型的一部分

     limit: undefined,

您能告诉我如何正确返回find（）回调中的“profile”吗

谢谢

这是不可能的，因为node.js使用了异步代码。

您可以在您的模型中创建一个方法，如下所示：

models.profile = db.define('profile', {
    id: { type: 'serial', key: true },
    another_column: { type: 'text' }
}, {
   methods: {
       checkLogin: function (username, password) {
           models.profile.one({ username, password }, (err, user) => {
               return user;
           });
       }
    }
}

从理论上讲，由于您在表单提交中有用户名和密码，因此可以执行以下操作：

req.models.profile.find({ username: username }, (err, user) => {
    return user.checkLogin(user.username, password);
});

这是可能的，您需要使用ORMs方法。见我下面的答复。
