问题 I understand that Ember.Application now has deferReadiness that lets me wait for the return of an AJAX call before initializing the app. However, in the example in the api docs, they put the value into a global variable in the App: App = Ember.Application.create(); App.deferReadiness(); jQuery.getJSON("/auth-token", function(token) { App.token = token; App.advanceReadiness(); }); Rather than introducing a global variable for the token, I want to place the returned value into my

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 3 years ago . Which of the following is better practice? {{my-component title=model.title body=model.body}} or {{my-component model=model}} Is there any difference between the two, or does it not really matter? 回答1: It's difficult to not subjectively judge something like this. But let's

问题 I have the following code which I expect to return [1000] but returns [undefined]: this.get('details').getEach('gross_total') But this.get('details')[0].get('gross_total') does work and returns 1000. I am using rc3 right now. The same code in rc1 worked fine. My persistence layer is taken from discourse. The relevant models are below. Invoice has_many details App.Invoice = App.Model.extend App.Commentable, invoice_number: App.Attr('string') description: App.Attr('string') issue_date: App.Attr

问题 I have this computed property alias in my component: firstElement: Ember.computed.alias('myArray.firstObject') This works in development, but doesn't update in production mode. This code though works in both development and production: firstElement: Ember.computed('myArray.[]', function() { return this.get('myArray.firstObject'); } Is the alias macro not allowed on firstObject , lastObject, etc..? It also seems weird that in works in development but not in production mode. 来源： https:/

问题 I have a mixed Ember/Rails app with a Rails route in the API namespace to take any single Event and convert it to an .ics file for import into a user's calendar (a la this question). Ember is running with the command ember server --proxy http://localhost:3000 , which is connecting it to the Rails server process. The below snippets illustrate my setup: Rails routes.rb snippet: namespace :api do # snip resources :events do # snip get 'export_event_ical', on: :member end end Rails events

问题 What I need is: 1) Represent list of partners App.Partner= DS.Model.extend( { name: attr(), site: attr(), contacts: DS.hasMany('partner-contact', { async: true, polymorphic: true }) } ); 2) and names of partners contacts App.PartnerContact = DS.Model.extend( { name: attr(), phone: attr(), post: attr(), email: attr(), partnerId: attr(), partner: DS.belongsTo('partner') } ); So I have route: App.CallsMyContactsRoute = Ember.Route.extend({ //needs: "partner-contacts", model: function () { return

问题 I'm ember.js newbie and facing daily problems :-) Today's problem is my server backend doesn't support sideloading . (If I understood 'sideload' right, it is server returns related models at once with multiple JSON root) for example, my server only returns below per request: for /api/v1/posts.json { posts: [{ id: 91, title: "ember.js" }, { id: 81, title: "ember-data.js" }] } for /api/v1/comments.json { comments: [{ id: 928, postId: 91, }, { id: 927, postId: 92, }] } When I load post model, go

问题 Child component property update is triggering all the parent component willUpdate , willRender , didUpdate and didRender life cycle hook methods. but I just updated property which is visible only the child component, It has nothing to do with parent component. Twiddle to check. Twiddle to check with powerselect - when mouse over dropdown option it's triggering the all of its parent component willUpdate , willRender , didUpdate and didRender life cycle hook methods.

问题 I want to use ember properties to toggle the visibility of a div by calling it's dynamic id, however even though I can do something similar by calling classes, I cannot do the same for id's. For example: {{bind-attr class=":class1 controller.controllerProperty:class2"}} works fine. I can toggle the controllerProperty from an action in my controller. You would think the same concept would apply to id's. However {{bind-attr id=":staticId controllerProperty:id{{dynamicIdNumber}}"}} makes the id
