Hello guys,

I tried different solutions/hacks(which I will list here) to load data from a hasMany relationship and view it in a nested route.(/posts/{post_id}/comments) I'am using a REST API server, without JsonAPI.

I hope you guys can help me out.

My situation:

I am trying to get a 'post' loaded in post.hbs with multiple 'comments' loaded in comments.hbs on a single page.

Models

Post.js

export default DS.Model.extend({
  comments: DS.hasMany('comment'),
  messsage: DS.attr()
});

Comment.js

export default DS.Model.extend({
  post: DS.belongsTo('post'),
  date: DS.attr()
});

Nested route

/posts/{post_id}/comments

REST Server API

GET /posts/{id}
{
 "id" : "1",
 "message" : "hello"
}

GET /comments?post={post_id}
[{
 "id" : "324",
  "date" : "01012015"
},
{
 "id" : "24",
  "date" : "02012015"
}]

Solution one

/routes/posts.js

model(params) {
  return this.store.findRecord('post', params: post_id );
}

/routes/posts/edit/comments.js

model() {
  let post=this.modelFor('posts/edit');
  return this.store.query('comment', { post: post.id });
}

This solution is working, but new added comments(using the route /posts/{id}/comments/new) are only visible after a reload of the page.

Solution two

/routes/posts.js

model(params) {
  return this.store.findRecord('post', params: post_id );
}

/routes/posts/edit/comments.js

model() {
  let post=this.modelFor('posts/edit');
  let comments=this.store.query('comment', { post: post.id });
  post.set('comments',comments);
  return post.get('comments');
}

This solution is working, but when the user navigates away and back through 'link-to' helpers the 'comments' are not shown, while they are still loaded in the store...

Solution three

/routes/posts.js

model(params) {
  return this.store.findRecord('post', params: post_id );
}

/routes/posts/edit/comments.js

model() {
  let post=this.modelFor('posts/edit');
  return post.get('comments');
}

/serializers/post.js

normalizeResponse(store, primaryModelClass, payload, id, requestType) {
....
  commentLink='/comments?post='+post_id
  result.links={ 'comments' : commentLink };
...
}

This solution works perfectly, but adding links to the payload in the REST serializer seems like a hack to me.
