如何向 Meteor.users 集合添加字段 [英] How to add fields to the Meteor.users collection

问题描述

我想要存储在客户端上我的用户文档中的 Facebook accessToken.按照流星文档，我应该添加一个新的发布调用.

I want the Facebook accessToken that is stored in my user's document on the client. Following the meteor documentation, I should just add a new publish call.

在 server.js 中:

Meteor.publish("access_token", function () {
  return Meteor.users().find(
    { _id : Meteor.userId() }, 
    {'services.facebook.accessToken': 1}
  );
});

在 client.js 中:

Meteor.subscribe("access_token");

好吧，这就是我迷路的地方.现在访问令牌是否应该只出现在 Meteor.users 集合中供登录用户使用?喜欢:

Alright, here's where I get lost. Should the accessToken just show up in the Meteor.users collection now for the logged in user? Like:

var user = Meteor.users.findOne({ _id : Meteor.userId() }); 
console.log(user); // includes services.facebook.accessToken now

显然，我已经尝试了上述方法，但没有显示 accessToken.是的，我已经确认 mongo 文档包含 services.facebook.

Obviously, I've tried the above and the accessToken doesn't show up. Yes, I've confirmed that the mongo document contains services.facebook.

那么...我是否创建一个新的客户端集合并以某种方式将其连接到新的发布?我如何获得 accessToken?

So... do I create a new client collection and somehow hook it up to the new publish? How do I get the accessToken?

推荐答案

你应该使用fields"关键字

you should use "fields" keyword

Meteor.users.find({ _id: this.userId },
    { fields: { the-extra-fields-that-you-want-go-here: 1 } }
);
