问题 I have a Post which has many comments. The problem is that I am able to fetch all the comments but I am unable to fetch a single comment and as a result cannot edit a single comment. Since I can't fetch a single comment, It means I can't add a single record to the transaction or edit a single record. The comments is sideloaded and will not be backed by a route and I don't want a route for any of the comment related controllers . So I am setting the model for the CommentController in the

问题 According to http://emberjs.com/api/data/classes/DS.EmbeddedRecordsMixin.html Records without an id property are not considered embedded records, model instances must have an id property to be used with Ember Data. If thats so how would i use a model like: { "_id": "545b54f20dbd7015f015359a", "comments": [ { "msg": "what is this jelly", "time": "1415271666", "user": { "id": "53fefc9ee4b07d3fe92fc077", "username": "kfir124" } } ], "files": [ { "key": "1415271653

问题 I'm trying to get some data out my templates to, let's say, add an user. This is what my view object looks like: Ember.View.create({ template: Ember.Handlebars.compile( UsersIndexTemplate ), addUser: function() { var value = $('#my-awesome-input').val(); } }) In theory I got my value already with jQuery, but is this the preferred way to go? 回答1: You should use bindings to bind the values in your template to properties on your view, see an example http://jsfiddle.net/pangratz666/uuvAp/:

问题 I am using Ember and Django and quickly found out that the template delimiter in Handlebar conflicts with that of Django Templates. So i intsalled Django-embers http://pypi.python.org/pypi/django-ember/0.1 But It just not seem to work properly. This is the problem: If I have something like this in APP.js var Ab = Em.Application.create({ appDescription : 'HelloWorldApp' }); I can easily render it in the template like this {% load ember %} {% handlebars "" %} {{Ab.appDescription}} {%

问题 I'm migrating an Ember 1.5 Handlebars app to current stable Ember and HTMLBars and it seems that a bound controller property must return "disabled" or null to work as expected with "disabled" DOM attributes. <button disabled={{isDisabled}}> In Handlebars isDisabled property is a boolean and all is well. In HTMLBars it seems I need: Ember.Controller.extend({ isDisabled: function() { if(this.get('itemSelected')){ return null; } else { return 'disabled'; } }.property('itemSelected') }); Is this

问题 I've followed the EmberFire guide to setting up authentication with the torii provider and it works perfectly. I'm looking to store the users data in firebase after the user has been authenticated and to have access to the user object throughout the application. I have previously done this with ember awhile back but i'm unsure how to do it using the new torii provider. I'm thinking i should test wether the user is already stored in firebase in an initialiser function and then inject the user

问题 I'm on Windows 8.1, with vagrant, Cheffile and everything works. Now I'm doing: npm install -g ember-cli and it's ok.

问题 I'm building a quiz generator as my first Ember project, but I'm struggling. I've been able to create, edit and delete quizzes and save them to localstorage, but I'm having trouble saving/deleting quiz questions for each quiz. I'm building it in Yeoman-Ember. I tried to add a demo to JSBin but it didn't work, so I've got a demo build here: http://test.richardwestenra.com/embertest/ and here's a zip containing the current state of the build: http://test.richardwestenra.com/embertest/dev.zip
