Accounts.onCreateUser未将字段添加到流星的用户集合

Question

I want to add a new field to Meteor's user collection:

server/fixtures.js:

Accounts.onCreateUser(function(options, user) {
  user.role = 'Student'
  // We still want the default hook's 'profile' behavior.
  if (options.profile)
    user.profile = options.profile;
  return user
})

But when I do Meteor.users.find().fetch(); :

Object
_id: "7zLDKQE4ACJCfeEhr"
username: "alex"
__proto__: Object

I don't see the field.

Isn't working in the template, either:

documents/document_page.js:

  users: function() {
    var users = _.map(Meteor.presences.find().fetch(), function(user) { 
      return Meteor.users.findOne({_id: user.userId})
    })

    return users
  },

documents/user.html

<template name="user">
  <li class="clearfix">
    <img src="/avatar.png"/>
    <div class="user-info">
      <p>{{userId}}</p>
      <p>{{username}}</p>
      <p>{{role}}</p>
    </div>
  </li>
</template>

Only username is showing. What could be the problem?

You need to publish the custom fields. From the docs:

By default the server publishes username, emails, and profile (writable by user). See Meteor.users for more on the fields used in user documents.

The easiest way to do this is just to publish with a name of null which will automatically publish the documents without the need for a corresponding Meteor.subscribe :

Meteor.publish(null, function() {
  return Meteor.users.find(this.userId, {fields: {role: 1}});
});

In this case we are publishing the role field which will be merged with the default fields already published for the current user.
