Handling multiple checkbox array in Ember.js - ember.js

Question

Here is the thing I have a form which have multiple checkboxes and they have the same name attribute "classifications[]"
with the code:
<input type="checkbox" name="classification[]" value="Value 1" />
<input type="checkbox" name="classification[]" value="Value 2" />
<input type="checkbox" name="classification[]" value="Value 3" />
this works properly by default it posts "classification[]" like this
[ 0 => "Value 1", 1 => "Value 2"]
but I want this to work in an ember app so I did this (shortened version)
// index.html
{{input type="checkbox" name="classification[]" value="Cell Member" checked=classification}}
App.ApplicationController = Ember.Controller.extend({
var user = this.store.createRecord('user',{
classification: this.get("classification")
})
user.save();
})
App.User = DS.Model.extend({
classification: DS.attr("string")
});
but the only posted classification value is True..

try this
// index.html
{{#for possibleValues}}
<label>{{this.label}}</label>
{{input type="checkbox" value=this.isChecked}}
{{/for}}
<a {{action save}}>save</a>
var possibleValue = [{
label: 'Label for value 1',
isChecked: false,
value: 'Value 1'
},{
label: 'Label for value 2',
isChecked: false,
value: 'Value 2'
},{
label: 'Label for value 3',
isChecked: false,
value: 'Value 3'
}];
App = Ember.Application.create();
App.ApplicationAdapter = DS.RESTAdapter.extend();
App.ApplicationController = Ember.ObjectController.extend({
init: function () {
this._super();
var user = this.store.createRecord('user');
this.set('content', user);
},
actions:{
save: function () {
var user = this.get('content'),
collected = user.get('classifications');
this.set('collected', collected);
user.save();
}
},
//executes when isChecked is changed in one item of possibleValues
collectChecked: function () {
var classifications;
classifications = this.get('possibleValues').filterBy('isChecked', true); //filter checked only
classifications = classifications.mapBy('value'); //map values
this.set('classifications', classifications);
console.log(classifications);
}.observes('possibleValues.#each.isChecked'),
possibleValues: possibleValues
});
App.RawTransform = DS.Transform.extend({
deserialize: function(serialized) {
return serialized;
},
serialize: function(deserialized) {
return deserialized;
}
});
App.User = DS.Model.extend({
classifications: DS.attr('raw')
});
