Troubleshooting Issue: Unable to Retrieve Loaded Record in Ember.js

I am facing an issue with accessing properties to change the header of my RESTAdapter after loading the user.

Do you have any ideas why that might be happening?

The code snippet in question is as follows:

var user = '';
App.MainRoute = Ember.Route.extend({
model: function(params){
    user = this.store.find('user',{email: params.email});
    alert(user.hash); //getting undefined
    return user;
},
actions:{
    addList: function(){
        var list = this.store.createRecord('list', {
            name: 'New list',
            desc: 'Describe it here'
        });
        this.store.find('user', 1).then(function(user){
            list.set('user', user);
        })
        list.save();
    }
}
})

The JSON response on

this.store.find('user', {email: params.email});
:

{
  "users": [
    {
      "id": 1,
      "hash": "66ff7d6eae591ca2a7d6b419991690e8",
      "email": "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="2d404c5f5b44433d20464f414c4e464144")">[email protected]</a>",
      "name": "",
      "lists": []
    }
  ]
}

Answer №1

To ensure Model returns a Promise, it's necessary to structure the code accordingly. The following snippet demonstrates how this can be achieved:

model: function(params){
    users = this.store.find('user', { email: params.email }); // retrieves promise
    users.then(function(item) { // resolves promise
        user = item.get('firstObject');
        alert(user.get('hash'));
    });
    return users; // model will wait for data to be available
}

This approach has been successfully implemented and can be integrated into a Handlebars.js template as shown below:

<script type="text/x-handlebars" data-template-name="main">
    From model:
    <ul>
    {{#each}} <!-- Iterate over array resolved from promise. -->
        <li>{{hash}}</li>
    {{/each}}
    </ul>
</script>
