问题 I can't figure out how Ember determines if it should update or create a record. I would assume its based on the ID or on the Store entry, but it seems to be something else. The code example clarifies: // this returns the user without making an api call currentUser.get('store').find('user_detail', '49') // this returns 49 currentUser.get('id') // this returns true currentUser.get('store').hasRecordForId('user_detail', 49) // this issues a create to api/userDetails instead // of updating /api

问题 I'm trying to use Ember Data to load a model. The AJAX call to fetch the model seems to be successful but I get the following Uncaught Error: assertion failed: A data hash was loaded for a model of type App.Account but no primary key 'undefined' was provided. In ember-data.js:1128 it seems to be deferencing undefined for the primaryKey and not defaulting to 'id' when a model doesn't specify a primaryKey. But I've also tried being explicit with the primaryKey to no effect. For completeness,

问题 What is the 'correct' way to bind from one model to another when the models are stored within an array? Typically I'd imagine that this would be a Controller's content array, but to keep the example simple: MyApp.websites = []; MyApp.websites.push(Ember.Object.create({ name: "Stackoverflow" })); MyApp.websites.push(Ember.Object.create({ name: "Serverfault" })); MyApp.favorite = Ember.Object.create({ // how should this be bound to a specific element of MyApp.websites? nameBinding: ????????? })

问题 I used to have a jQuery app, that had a 'keydown' event once the document was ready. Basically, anytime a user hit a key, it would match the keycode and do something. Now I ported this app to Ember and life became difficult for 2 reasons: 1) The only time a 'keyDown' event can be registered is when the containing element/View has a focus on it. The only way this can be done with non-input fields is by setting the tabindex value, to achieve this, I do this: didInsertElement:function(){ this.$(

问题 Its been a long day and this is probably extemely simple but how do i add a name attribute to a Ember.TextField ? I want to do something like this : {view Ember.TextField valueBinding="your_name" placeholder="Your name" name="your_name"}} This works with the placeholder but ignores the name. Any ideas ?? thanks Rick 回答1: The name attribute is not bound by default, see As a workaround, you could create your own TextField , see http://jsfiddle.net/fkPzr/ App.TextField = Ember.TextField.extend({

问题 When i visit one route and then go to another, is where a way to know which route i came from? I tried document.referrer - this doesn't work. Googling hadn't brought any answers either.. I set up this fiddle for example and testing.. 回答1: There is no direct solution using the API. Meaning, this information is not part of the public API. However, you can cache this information yourself. App.set('lastRoutes', []); App.BaseRoute = Ember.Route.extend({ setupController: function() { this._super
