Question

I have a model like:

TestModel = Em.Object.create({
    id:'',
    name:''
})

and a object ArrayController like:

testArrayController = Em.ArrayController.create({
    content: [],
    init: function() {
        //push some object TestModel
    }
});

I want to remove some objects depend on id property of a object in content array. How to do that?

Answer 1

I would use a combination of findProperty and removeObject, see http://jsfiddle.net/pangratz666/rXN4E/:

App.testArrayController = Em.ArrayController.create({
    content: [],

    removeItem: function(propName, value){
        var obj = this.findProperty(propName, value);
        this.removeObject(obj);
    }
});

App.testArrayController.removeItem('id', 42);
