Save model on _any_ attribute change


#1

I’m wondering if theres a build in way to ‘automatically’ save a model when one of its attributes has changed? I tried something to implement in a controller like this:

//base controller
export default Ember.ObjectController.extend(TStringGet, {
    modelChange: function () {
        console.log('model changed: ', this.get('model'));
       // model.save() will be called here

    },
    watchModel: function () {
        var _this = this;
        this.get('model').eachAttribute(function (name, meta) {
            _this.addObserver(name, _this.modelChange);
        });

        this.get('model').eachRelationship(function (name, meta) {
            //
        });
    }.observes('model')

It seems to work for standard atributes but for a belongsTo relation attribute I’m not sure how to handle this (have a related model selectable in a dropdown and when changing it nothing happens… ) . In general, I’m not really sure if this is the most standard way to do this ember…
