Hey guys,

I need help…again 😄

My project have a model Conversation and a model Message. And I configure Conversation with hasMany Messages and Messages belongsTo Conversation.

That’s ok, but when I route to url [http://localhost:4200/conversations](http://localhost:4200/conversations) I need to list all conversations and when user click in an specific conversation I load the messages belongs to this conversation.

But when I try to access conversation.messages.content this does not works.

```
{{#each model as |conversation| }}
   {{conversation.messages.name}}
{{/each}}

```

I only can access the attributes of model Conversation but can’t access attributes of Messages. And when I print {{conversation.messages}} I receive this: subclass of Ember.ArrayProxy.

Anyone can help me understand where I’m be so stupid? 😆 I search all the documentation and can’t understand.

`conversation.messages` is an array, since each conversation has many messages. So it doesn’t make sense to access the name of a list of messages. If you want to get the name of each message, you’ll need an inner loop to iterate through the messages.

```auto
{{#each model as |conversation|}}
  {{#each conversation.messages as |message|}}
    {{message.name}}
  {{/each}}
{{/each}}

```

This make sense. You are right it! I forgot it. But this doesn’t work, I’m have a fake API with ember-cli-mirage with Adapter and Serializer in JSONAPI. In my routes/conversations/index.js I have this:

`return this.store.findAll('conversation');`

And I also try this:

`let conversation = this.store.findAll('conversation');`

`conversation.get('messages').then((messages) => { return conversation });`

But can’t access attributes of messages ☹ I’m loosing my mind with this 😆

OK, I found the error.

Like I say, I’m using JSONAPI. So in my serializers/application.js I defined this:

`import DS from 'ember-data';`

`import Ember from 'ember';`

```
export default DS.JSONAPISerializer.extend({
  keyForAttribute: function(attr) {
    return Ember.String.underscore(attr);
  },
  keyForRelationship(key, relationship) {
    if (relationship === 'belongsTo') {
      return `${key}_id`;
    }
  }
});

```

So I thought it was working. But not. I change for this:

```
import DS from 'ember-data';
import JSONAPISerializer from 'ember-data/serializers/json-api';
import Ember from 'ember';

export default JSONAPISerializer.extend({
  keyForAttribute: function(attr) {
    return Ember.String.underscore(attr);
  },
  keyForRelationship(key, relationship) {
    if (relationship === 'belongsTo') {
      return `${key}_id`;
    }
  },
 attrs: {
  messages: { serialize: true }
 }
});

```

And now this works. Now I can access the model Messages 🙂 😊
