如何用Sails-mongo按id选择文件？ [英] How to select document by id with Sails-mongo?

问题描述

User.find({ _id: { '!': user.id } }, function foundFriends (err, friends) {
    if(err) return next(err);
        res.view({
            friends: friends
        });
});

MONGODB :

 {
    _id: ObjectId("53b942f7c8638f7b17670acc"),
    name: "PH",
    admin: true,
    online: false,
    encryptedPassword: "$2a$10$PjcPRgL67ZSOWDjmEwTkvu30xKeDXdCwgZ.D0.bjyDRw9sOfS/4UK",
    createdAt: ISODate("2014-07-06T12:37:11.522Z"),
    updatedAt: ISODate("2014-07-09T18:22:47.25Z")
}

此代码不起作用，我想通过Id选择文档。我不知道在我的帆项目中应该怎么做才能解决这个问题。谢谢你的帮助。

This Code doesn't work, I would like to select document by Id. I don't know what I should do to fix that in my sails project. Thank you for your help.

推荐答案

我看到的一些事情对你的代码很奇怪。

1.应该使用.exec（）

来执行与风帆10相关的回调函数。我认为你不应该搜索 _id 但仅限于 ID 。我认为waterline解析了这个下划线。

There are couple of things I see are weird with your code.
1. The callback function as for sails 10 should be executed with .exec()
2. I think you should not search for _id but only id. I think waterline parses this underscore.

考虑到这一点，你的代码应该类似于

Having that in mind your code should look something like

User.find({ id: { '!': user.id } }).exec(function (err, friends) {
    if(err) return next(err);
    res.view({
        friends: friends
    });
});
