问题 Using gem "ember-rails" for an existing rails app. I'm attempting to route one resource using Ember, and I've been told by a number of people that this code should work, but it's not.

阅读更多关于 Using handlebars end-up displaying nothing

问题 First, I'm a new user so if this is not the place to ask this question or the question is leaking with details please inform me and I'll do the required adjustments. I'm new to Ember.JS and I've recently started learning by reading this getting started guide. In the early stages of this guide I'm already dealing with the next problem: All stages worked well until the stage where I need to update my index.html to wrap the inner contents of <body> in this Handlebars script tag: <script type=

Binding static and dynamic classes with HTMLBars

阅读更多关于 Binding static and dynamic classes with HTMLBars

问题 I'm trying to bind a static class 'form-control' and a dynamic property value 'color' to the class attribute of an input helper, however, the syntax I'm using just outputs this to the rendered DOM element class="form-control {{color}}" without actually binding the value of 'color' to the class attribute. I know that this is the way to bind static and dynamic classes in normal DOM elements with HTMLBars, but is there a different syntax for elements that use curly-braces? The syntax I'm using:

RSVP - Handling timeouts with promises

阅读更多关于 RSVP - Handling timeouts with promises

问题 I am using ember.js and RSVP. From what I can see, there is nothing that handles a timeout from an async call. My thinking is to wrap the resolve handler using the decorator pattern to wrap the resolve handler in some code that will time the call and call reject if the timeout happens. Does this sound like a good idea or is there some built in support for timeouts that I have missed in RSVP. 回答1: You can do that, but this should probably be handled by whatever is doing the async operation. If

Refresh / Reload ember route from a component

阅读更多关于 Refresh / Reload ember route from a component

问题 I have a component, that's actually a modal dialog. When I am done with that dialog and press the "Ok" button, I want to stay on the stay page from where I opened that dialog. Which isn't difficult. But the problem is that the dialog changes the data (I am getting data through a REST call) so I need to refresh the route that I already am on to reflect the data changes. Since, I am calling it from a component, I don't have Route so can't call route.refresh() . I tried to get the router: this

EmberJS: Object as Query Param to Refresh Model

阅读更多关于 EmberJS: Object as Query Param to Refresh Model

问题 I followed the Query Params guide (http://guides.emberjs.com/v1.11.0/routing/query-params/) and it worked great. Specifically, refreshing the model did exactly what I wanted. I'm moving the filter to the json-api spec and filtering takes place in a filter object. So rather than: http://localhost:3000/accounts?id=1 The server responds to: http://localhost:3000/accounts?filter[id]=1 I tried to get the query params to work refreshing the model based on an object, but it doesn't seem to update. /

Ember cleanup on leaving route

阅读更多关于 Ember cleanup on leaving route

问题 I want to make some cleanup when i leave route, like stopping timers. For that i need an event that triggers when leaving the route, and i need access to instance of controller inside of that event. There is an exit event, but it doesn't get any arguments, and this.get('controller') inside it doesn't work too - returns undefined . Is there a proper way for obtaining controller instance in the exit event, or, maybe, another event that i don't know of? I setup this fiddle with an example of

Making Loopback API Ember.js compatible

阅读更多关于 Making Loopback API Ember.js compatible

问题 I'm trying out Loopback for an API that will talk to Ember. Ember requires JSON to be contained in 'keys', e.g. for an account: { account: { domain: 'domain.com', subdomain: 'test', title: 'test.domain.com', id: 1 } } I've found some advice on the Google group about how to alter the response so that Ember will receive it, using afterRemote hooks. E.g. in my models/account.js: module.exports = function(Account) { Account.afterRemote('**', function (ctx, account, next) { if(ctx.result) { if
