问题 I have an ember-data model definition that looks like this: Sylvius.Filter = DS.Model.extend({ title: DS.attr('string'), slug: DS.attr('string'), // Belongs to Atlas atlas: DS.belongsTo('Sylvius.Atlas'), // Has images images: DS.hasMany('Sylvius.Image'), // May have AtlasExtras extras: DS.hasMany('Sylvius.AtlasExtra'), // Structures for this filter structures: DS.hasMany('Sylvius.Structure'), // This is the path to the thumbnails sprite. // Each image will have an index on this sprite

问题 I'm developing an application using ember.js and a rest API written with spring MVC. I have to create a dashboard with several widget on it. Every widget as its own behavior and will call different API method. I was thinking to have one controller subclass for each kind of widget. Then will instantiate them and will add ther views to a Container view. However ember will create a instance for each controller automatically, so is it a good path to follow? Any suggestion fom the ember.js

问题 I have a Ember.Mixin which observes one of its properties (here bar.baz ). I've extended this Mixin and set bar.baz in the .create() parameter, but my observer is not called. Here is my code : App.FooMixin = Ember.Mixin.create({ barBazDidChange: function() { console.log('barBazDidChange'); // never called }.observes("bar.baz") }); App.Foo = Ember.Object.extend(App.FooMixin); App.fooObject = App.Foo.create({ bar: Ember.Object.create({ baz: "ember" }) });​ And the associated jsfiddle : http:/

问题 My Ember app has a route that contains 2 different components and one controller with an index.hbs template. Here's what it looks like: 1) A user can select multiple filters from the dropdowns of the Filter Component 2) The DataGrid is a separate component from the filter 3) A user can select multiple rows from the DataGrid by checking boxes 4) Create Custom Report button fires "sendAction" to the route's controller This data is not model-specific... it's just temporary data that is required

I am looking for some practical advice about when to use each or collection and what are the differences between the two methods. 回答1: Each: App.myArray = [1,2,3] {{#each value in App.myArray}} <p>{{value}}</p> {{/each}} corresponding HTML <p>1</p> <p>2</p> <p>3</p> Collection: {{#collection contentBinding="App.myArray"}} <p>{{view.content}}</p> {{/collection}}

问题 I have a mixin app/mixins/ui-listener.js which I'm struggling to use with Ember-CLI. I'm trying to use the mixin with the following syntax: import ListenerMixin from './mixins/ui-listener'; export default Ember.Component.extend(ListenerMixin,{ // class definition } This fails when I save it, complaining that ENOENT, no such file or directory 'tmp/tree_merger-tmp_dest_dir-74tK3rvD.tmp/[app-name]/components/mixins/ui-listener.js' It seems funny that the "mixins" directory is nested under the

问题 I have a controller that contains an array of "things". Within each of these things is an array of "subthings". I'd like to create a computed property that contains all subthings in all things (a flattened array of subthings). My computed property depends on things.@each.subthings.length . I find that if I set the subthings property of a thing, my computed property is updated. However if I call pushObjects to add new data to my existing subthings array, my computed property does not update. I
