流星&account-base - 如何获取不同用户的数据 [英] Meteor & account-base - how to get data for different users

问题描述

我有从 Meteor-admin 存根创建的 Meteor 基本项目:(https://github.com/yogiben/meteor-admin)

I have basic project in Meteor created from Meteor-admin stub: (https://github.com/yogiben/meteor-admin)

我需要为所有用户显示头像，而不仅仅是当前用户.为了显示用户的头像，我需要他的电子邮件地址.(我正在使用实用程序:avatar https://atmospherejs.com/utilities/avatar)

I need to display avatars for all users, not only current one. For displaying user's avatar I need his email address. (I am using utilities:avatar https://atmospherejs.com/utilities/avatar)

问题:我应该对项目进行哪些调整才能访问其他用户的数据?

Question: what adjustments to project should I make to be able to access other users' data?

可能与发布用户有关.

目前我有:

{{> avatar user=getAuthor shape="circle" size="small"}}         

getAuthor: ->
  console.log 'Owner:'
  console.log @owner
  user = Meteor.users.findOne(@owner)
  console.log user
  user

这会为所有用户正确打印 Owner: @owner (id)，但仅为当前用户填充 user 对象.

This correctly prints Owner: @owner (id) for all users, but user object is only populated for current user.

我在服务器端也有这个代码:

I also have this code in server-side:

Meteor.publishComposite 'user', ->
  find: ->
    Meteor.users.find _id: @userId
  children: [
    find: (user) ->
      _id = user.profile?.picture or null
      ProfilePictures.find _id: _id
    ]

(儿童/个人资料图片无关紧要)

(children / ProfilePicture are irrelevent)

我认为 account-base 库会关闭发布功能还是什么?感谢帮助！

I think account-base library turns publishing off or something? Thanks for help!

额外问题:我只想访问有关用户的一些信息(电子邮件地址).

Bonus question: I would like to access only some info about an user (email address).

推荐答案

如果删除包 autopublish，则需要明确指定服务器向客户端发送的内容.你可以通过 Meteor.publish 和 Meteor.subscribe 来做到这一点.

If you remove the package autopublish, you need to specify explicitly what the server sends to the client. You can do this via Meteor.publish and Meteor.subscribe.

例如，要发布您可以执行的所有用户的电子邮件地址:

For instance, to publish the email addresses of all users you could do:

if (Meteor.isServer) {
    Meteor.publish('emailAddresses', function() {
        return Meteor.users.find({}, {
            fields: {
                'email': 1
            }
        });
    });
}

之后，您需要订阅客户端上的发布:

After that, you need to subscribe to the publication on the client:

if (Meteor.isClient) {
    Meteor.subscribe("emailAddresses");
}

详细了解Meteor 的发布和订阅功能.
