publish subscribe - Meteor Group Collection by Field -

i trying return collection (postings) grouped field (status). pretty new mongo , meteor. query below gives me collections grouped status # of docs status... want same thing have actual documents in there.

also, able publish/subscribe reactivly update. creating admin dashboard groups postings current status.

a friend provided following gist, bit on head: https://gist.github.com/ryw/8827179

db.postings.group({ key: {status: 1}, initial: {sum:0}, reduce: function(doc, prev) { prev.sum += 1; } }) 

thanks!

if need of documents on client, publish whole collection , let template code group them.

client

tracker.autorun(function() {   if (meteor.user()) {     meteor.subscribe('allpostings');   } });  template.admin.helpers({   postings: function() {     if (session.get('currentstatus')) {       return postings.find({status: session.get('currentstatus')});     }   },   statuses: function() {     return _.uniq(_.pluck(postings.find().fetch(), 'status'));   } });  template.admin.events({   'click .status': function() {     session.set('currentstatus', string(this));   } }); 

<template name="admin">   <div class="left-panel">     <ul>       {{#each statuses}}       <li class="status">{{this}}</li>       {{/each}}     </ul>   </div>   <div class="right-panel">     <ul>       {{#each postings}}       <li>{{message}}</li>       {{/each}}     </ul>   </div> </template> 

server

meteor.publish('allpostings', function() {   var user = meteor.users.findone(this.userid);   if (user.isadmin) {     return postings.find();   } }); 

i'm assuming have way identify admin users (here used isadmin). assuming posting has status , message.
