问题 My application backend has several resources. A model is exposed for each resource. The entry point to all other resources is through the User model. What I mean is, given a User we can find BlogPost . Given a BlogPost we can find Comments etc. In Ember terminology, we could say: User hasMany BlogPost BlogPost hasMany Comment Comment belongsTo BlogPost By backend exposes REST APIs of the form: GET /api/v1/users/1 GET /api/v1/users/1/blog_posts/1 GET /api/v1/users/1/blog_posts/1/comments/1 I'm

问题 I have render-component ( source ) which used to render components/helpers from controller fields. It worked fine for ember 1.9.1 but after updating up to ember 1.12.1 I found changes in API. After updating code I restore simple cases ( like render view by name from some property ). But largest part of functionality still broken. I'm interesting about where can I read more about such things like env ( which used inside components/helpers internal implementation ) morph ( I understand that it

问题 I am having a issue with my DS.Model parsing dates in the format of "YYYY-MM-DD". They are always one day behind. Here is an example: http://jsfiddle.net/ZUV8v/ Using Date objects on the console I get similar results > new Date('2012-09-20') Wed Sep 19 2012 17:00:00 GMT-0700 (PDT) Is this a ember bug or a javascript bug or a Chrome bug or am I missing something? Chrome Version 21.0.1180.89 on OSX 10.7 回答1: I ran into this just the other day. According to the ECMAScript Specification 15.9.1.15

问题 If I have two components: nav-menu nav-button and nav-menu is a block component that would contain nav-button like so: {{#nav-menu}} Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

问题 Perhaps some folks just know the answer, but I am trying to understand the following: Say you are declaring a view: App.FooView = Ember.View.extend({}); Now referencing this view in App.Router results in the following error: router.get('applicationController').connectOutlet('Foo') When I reference Foo the console states: Uncaught Error: assertion failed: The name you supplied Foo did not resolve to a controller FooController I could not find anywhere in the docs explaining the args. Perhaps

问题 I'm making an app that retrieves data of an API which is not in my control. I have the following scenario: The path for retrieving the posts is /api/posts . So I configured my ApplicationAdapter as follows: App.ApplicationAdapter = DS.RESTAdapter.extend({ namespace: 'api' }); The url for retrieving comments is '/api/posts/1/comments'. You can see that the url is prefixed by the path for retrieving a single post followed by the default path /comments . Ember data defaults to /api/comments .

问题 What I want to do is, make an ajax call whenever user stops entering something in the 'projectname' field & check it against database & show an kind of error message saying, "It exists". But the keypress event is not working as expected, first of all it omits the first letter entered & as a result word is not sent to database completely. Here's my Controller : App.ProjectController = Ember.ArrayController.extend({ actions : { createNew : function() { data = { projectname : this.get(

问题 I have an ember.js wizard control with a number of steps. An ember model object has its various properties set at each stage of the wizard. The only way I can see of changing the view is to use the linkTo helper like this: {{#linkTo steps.two model}}Step 2{{/linkTo}} But this is no good to me as I will need each step that I linkTo to to be a dynamic route: @resource "steps", -> @route "one", {path: 'one/:model_id'} @route "one", {path: 'two/:model_id'} #etc. The dynamic route is no good
