问题 I am still getting the error below despite having following the instructions on this link Ember.js: HtmlBars and the Handlebars.compile command. Below I have copied and pasted my package.json,bower.json and brocfile.js. Not sure what is causing the issue. Uncaught Error: Cannot call compile without the template compiler loaded.

问题 I am trying to write a simple Ember integration test and continue to get the frustrating run loop error despite using Ember.run . I've had a nightmare of a time trying to get this to work, if anyone could help me I'd be so grateful. Specifically, I can see the test sign in and begin loading the next page (as it should), but as soon as the test finishes I get that error. This is regarding the second test, the first passes (as nothing is async I believe). import Ember from 'ember'; import

问题 Ember Data's REST Adapter accepts the JSON from the server in this format: Taken from the documentation: http://guides.emberjs.com/v1.10.0/models/the-rest-adapter/ { "post": { "id": 1, "title": "Node is not omakase", "comments": [1, 2, 3] }, "comments": [{ "id": 1, "body": "But is it _lightweight_ omakase?" }, { "id": 2, "body": "I for one welcome our new omakase overlords" }, { "id": 3, "body": "Put me on the fast track to a delicious dinner" }] } Is it possible to have this kind of JSON

问题 From the ember docs its clear you should be able to save a dirty model var m = App.MyModel.find(10) ; ... m.set("firstName", "John") ; m.get("isDirty") ; // --> true Now, I don't know how to save, things like m.save() ; App.MyModel.save(m) ; //etc do not work. Any suggestions ? CHeers 回答1: EDIT: This is now out of date with Ember Data 1.0 beta and onwards, please refer to Bart's answer If you are using Ember-Data, you need to call commit() on the model's transaction. m.get('transaction')

问题 I've got something like this: Epic = Ember.Object.extend({ children:[], children_filtered: function(){ return this.get("children").filterProperty("archived",false); }.property("children"), init: function() { this._super(); this.set("children", Ember.ArrayController.create({content:[]}) ); this.set("stories", Ember.ArrayController.create({content:[]}) ); }, }); Note the children_filtered computed property. If I use children_filtered in a view... {{#each content.children_filtered }} hi {{/each}

问题 Entire error: Uncaught Error: Assertion Failed: You may not set `id` as an attribute on your model.

问题 Is there a way to break from the forEach iterator in Ember? I tried to return false in the callback (a la jQuery) but it does not work. Thanks! PJ 回答1: Ember uses the native Array.prototype.forEach if it's available, and emulates it if not. See https://github.com/emberjs/ember.js/blob/v1.0.0-rc.1/packages/ember-metal/lib/array.js#L45. JavaScript's forEach doesn't support breaking. See https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array/forEach 回答2: You can use

问题 I've been digging into EmberJS for one day :). I've followed several examples. Some examples used ArrayProxy while others used ArrayController. I looked at the unminified source code and..guess what...Ember.ArrayController is simply extending Ember.ArrayProxy, but there's no extra methods or features in ArrayController. So..my question is..why do we have two same classes? 回答1: There is no difference between the two classes. It's for all of us who are coming from SproutCore 0.9.x, 1.x and

问题 I'm trying to build a Ember app with PHP REST framework as my api locally. The Ember app is being served at http://localhost:4200 and the api is being served from just http://localhost . This is causing a CORS issue. I've tried everything that I can think of, but I keep getting an error back saying the request was blocked and that the preflight channel did not succeed. It doesn't succeed in Firefox or Chrome. I've added the following to the .htaccess file for my api: Header set Access-Control
