Ember.PromiseProxyMixin Class
PUBLIC
Defined in: packages/ember-runtime/lib/mixins/promise_proxy.js:34
Module: ember-runtime
A low level mixin making ObjectProxy promise-aware.
let ObjectPromiseProxy = Ember.ObjectProxy.extend(Ember.PromiseProxyMixin); let proxy = ObjectPromiseProxy.create({ promise: Ember.RSVP.cast($.getJSON('/some/remote/data.json')) }); proxy.then(function(json){ // the json }, function(reason) { // the reason why you have no json });
the proxy has bindable attributes which track the promises life cycle
proxy.get('isPending') //=> true proxy.get('isSettled') //=> false proxy.get('isRejected') //=> false proxy.get('isFulfilled') //=> false
When the $.getJSON completes, and the promise is fulfilled with json, the life cycle attributes will update accordingly. Note that $.getJSON doesn't return an ECMA specified promise, it is useful to wrap this with an RSVP.cast
so that it behaves as a spec compliant promise.
proxy.get('isPending') //=> false proxy.get('isSettled') //=> true proxy.get('isRejected') //=> false proxy.get('isFulfilled') //=> true
As the proxy is an ObjectProxy, and the json now its content, all the json properties will be available directly from the proxy.
// Assuming the following json: { firstName: 'Stefan', lastName: 'Penner' } // both properties will accessible on the proxy proxy.get('firstName') //=> 'Stefan' proxy.get('lastName') //=> 'Penner'
