问题 All the examples are using fixed data source in the arraycontroller.content, while I am using dynamic data source which is generated from anther web service and returns a JSON, it won't create an object that I declared in Ember, here is the code sample: ET.AppYear = Ember.Object.extend({ text:null, value:null }); ET.EmailTypes = Ember.Object.extend(); ET.appYearController = Ember.ArrayController.create({ content: [], loadYears: function (year) { if (year != null) { for (var i = -5; i < 5; i++

问题 I'm trying to use Bootstrap Popover with EmberJS, so that the content of the popover will be a ember/handlebars template (with binding etc). How can this be done?

问题 I have two models: App.User = DS.Model.create({ comments: DS.hasMany('App.Comment') }); App.Comment = DS.Model.create({ user: DS.belongsTo('App.User') }); When a user is deleted, it also will delete all its comments on the backend, so I should delete them from the client-side identity map. I'm listing all the comments on the system from another place, so after deleting a user it would just crash. Is there any way to specify this kind of dependency on the association?

This is what I have: {{#view App.AccountSelectedView contentBinding="App.selectedAccountController.everythingSorted"}} {{#with content}} <ol class="timeline"> {{#each this}} {{#is
