How to use belongsTo in ember-model? - ember.js

Question

I have created FIXTURES using ember-model, but i am not able to use following node on template
"logged_in": {
"id" : "1",
"logged": true,
"username": "sac1245",
"account_id": "4214"
}
I have implemented belongsTo relation for this node but it throwing one error : Uncaught Error: Ember.Adapter must implement findQuery
Here i have listed my model code :
Astcart.Application = Ember.Model.extend({
name: Ember.attr(),
logo_url : Ember.attr(),
list: Ember.hasMany('Astcart.List', {key: 'list', embedded: true}),
logged_in: Ember.belongsTo('Astcart.Logged_in', {key: 'logged_in'})
});
Astcart.List = Ember.Model.extend({
name: Ember.attr()
});
Astcart.Logged_in = Ember.Model.extend({
id: Ember.attr(),
logged: Ember.attr(),
username: Ember.attr(),
account_id: Ember.attr()
});
Astcart.Application.adapter = Ember.FixtureAdapter.create();
Astcart.Application.FIXTURES = [
{
"id" : "1",
"logo_url": "img/logo.jpg",
"logged_in": {
"id" : "1",
"logged": true,
"username": "sac1245",
"account_id": "4214"
},
"name": "gau",
"list": [
{
"id" : "1",
"name": "amit"
},
{
"id" : "2",
"name": "amit1"
}
]
}
];
Template code :
{{#each item in model}}
{{item.name}}
{{item.logged_in.logged}}
{{/each}}
Router code :
Astcart.ApplicationRoute = Ember.Route.extend({
model: function() {
return Astcart.Application.find();
}
});
Can any one show me how to access data of above node in template?

Answer 1

Your current fixture have the logged_in data embedded:
Astcart.Application.FIXTURES=[
{
...
"logged_in": {
"id": "1",
"logged": true,
"username": "sac1245",
"account_id": "4214"
},
...
}
];
So the logged_in property mapping need the parameter embedded: true, to be able to find this data, as follow:
Astcart.Application = Ember.Model.extend({
...
logged_in: Ember.belongsTo('Astcart.Logged_in', {key: 'logged_in', embedded: true })
});
Without this it will try to query for the Astcart.Logged_in:
Astcart.Logged_in.find(1)
and because it doesn't have an adapter, will fail with the exception: Uncaught Error: Ember.Adapter must implement findQuery
