javascript - Matching collection items by id -

relations between 2 mongo collections.

i have 2 collections: entries , labels:

// example entry {   "_id": "4zcbv5oglstffxpvp",   "title": "some other title",   "entrylabels": [     "tfryveujpqbmrywez",     "rn8z57nseyse7nyto",     "rn8z57nseyse73yto"   ],   "author": "tmvirl8otm3zsddst",   "createdat": "2016-01-16t15:21:43.153z",   "date": "2016-01-16t15:21:43.153z" }  // example label {   "_id": "9ncnpgh8f5mwnzjka",   "color": "#333",   "name": "grey label",   "author": "tmvirl8otm3zsddst" } 

as it's possible have multiple labels entry, keep label ids in entrylabels field. plan save label ids , query labels collection based on that.

this ok if have single labelid because can query labels collection based on id , return label. have array of ids , have return multiple labels.

my attempt this(in template helper) :

labels: function(event){     var entrylabels = this.entrylabels;      var arr = []     for(i = 0; < entrylabels.length; i++) {         var label = entrylabels[i];         var thelabel = labels.find({_id: entrylabels[i]}).fetch();          arr.push(thelabel);     }      return arr; } 

then, in template:

{{#each labels}}     {{name}}     <p>asd</p> {{/each}} 

---

this returns 'asd' 3 times cannot access label properties name

so, guess question is, how can access properties. also.. doing right way?

am doing right way?

i no. mongo other database, can retrieve multiple documents @ time. why fetch 1 @ time in for-loop when can do

labels: function(event){     var entrylabels = this.entrylabels;     var arr = labels.find({_id: {$in: entrylabels}}).fetch();     return arr; } 

this fix "i cannot access label properties name" problem, because old arr array of array of documents, not array of documents expected.
