For example: // config/settings.json { "title": "Hello World" } // config/foo.json { "bar": "baz" } // Template {{ settings.title }} {{ foo.bar }} 回答1: You need to use dependency injection to inject you global variables into the controller.

问题 I've been working all week to get authentication working. I have gotten it working with Ember-CLI Ember-Simple-Auth Torii google-oauth2 provider However I have proven unsuccessful in getting the users information from google.

问题 Using Object.create one can define setter and getter methods in javascript. o = Object.create(Object.prototype, { fooBar: { get: function() { return "Meh" }, set: function(value) { console.log(value) } } }); console.log(o) will always return Meh, and doing o = "Heyo" would only output the new value directly without changing o . Is there any reason as to why I should not use, or rely on this behavior to trigger events? What about two-way binding frameworks like angular and ember, do they make

问题 I am trying to build a simple Todo List using all the last routes and data stuff for ember.

问题 I'm trying to set up a basic datastore at firebase when following simple beginner tutorials on Ember js 2.0.

问题 I want to know how to abort a request. For example, I issue App.MyModel.find() and later i want to cancel/abort it before it returns from server. I would expect something like this: var res = App.MyModel.find(); //request sent to server res.abort(); // abort the request before completion but this doesn't work - the returned object is a promise and there is neither abort nor cancel methods.

问题 First a Merry Xmas to you and thanks for helping with suggestions.
