Ember - Sideloading data within RESTAPISerializer - rest

Question

I am trying to sideload data with RESTAPISerializer, but there seems to be some problem.
The goal is to store articles with tags. The articles appear in the store just fine, and I can look at them with Ember inspector. But I can't seem to figure out how to store the tags, they never show up in the inspector.
I created a model called blog-tag to store the tags. They come in a specific format, which I can't change, and it looks like this:
tid:term
... and I am getting an array of them with each article.
The article model includes a hasMany relationship with blog-tags. I am trying to pass them in through the serializer, and have been using various formats (JSON, javascript arrays, etc.) I wrote a custom serializer for blog tags as well, but it doesn't seem to do much.
Can someone explain what I am missing?
The article model:
import DS from 'ember-data';
import Model from 'ember-data/model';
import attr from 'ember-data/attr';
export default Model.extend({
title: attr(),
blogTags: hasMany('blog-tag', { async: true })
});
The blog-tag model:
import Model from 'ember-data/model';
import attr from 'ember-data/attr';
export default Model.extend({
tid: attr('number'),
term: attr('string'),
});
The article serializer:
import RESTAPISerializer from 'ember-data/serializers/rest';
export default RESTAPISerializer.extend({
normalizeResponse: function(store, primaryModelClass, payload, id, requestType) {
var normalizedPayload = {articles: []};
payload.forEach(function(item) {
var tags = item.tags.split("|"), blogTags = [];
// storing blog tags in an array, have also done it as a
// JSON structure
var blogTags = tags.map((tag) => {
var item = tag.split(":"),
vals = {};
vals.tid = item[0];
vals.term = item[1];
return vals;
});
var article = {
id: item.nid,
title: item.title,
blogTags: blogTags,
};
normalizedPayload.articles.push(article);
});
return this._super(store, primaryModelClass, normalizedPayload, id, requestType);
},
});

Solved my own problem. Answering the question for the benefit of anyone else running into the same issue.
What I was trying to do is embed the tags from the articles serializer. This mean I needed to use the EmbeddedRecordsMixin.
http://emberjs.com/api/data/classes/DS.EmbeddedRecordsMixin.html
It was actually pretty simple to do this. Made the following changes to the serializer described above, the code worked as-is with these additions.
// app/serializers/articles.js
import RESTSerializer from 'ember-data/serializers/rest';
import EmbeddedRecordsMixin from 'ember-data/serializers/embedded-records-mixin';
export default RESTSerializer.extend(EmbeddedRecordsMixin, {
attrs: {
blogTags: { embedded: 'always' }
}
});
