Meteor collection - count same values


Tag: mongodb,collections,meteor,spacebars

I need to count all products in descending order and display them with spacebars. How would I do that? Result should be:
book : 2
tv : 1

// My Collection
Records = new Mongo.Collection('records');

// My database
    name: "a", product: "book"
    name: "b", product: "tv"
    name: "c", product: "book"

// My Template Helper - This sorts for alphatical order{
'counterRecords': function(){
    return Records.find({}, {sort: {product: 1}});

// My Template
{{#each counterRecords}}
 {{counterRecords}}: {{counterRecords.count}}


Give this a try:

  counterRecords: function() {
    var records = Records.find().fetch();
    return _.chain(records).pluck('product')
      .map(function(v, k) {return {product: k, count: v};})

That should produce an array like:

[{product: 'book', count: 2}, {product: 'tv', count: 1}]

And your template could look something like this:

{{#each counterRecords}}
 {{product}}: {{count}}
