问题 I am able to generate a URL using urlFor() when I’m in the route /1/1/orders . but I’m unable to generate a URL in the application route. So this code is not working: var routeName = "scope.purchase.invoice"; var dynamicSegments = { scopeId: 1, scopeData: 2, invoiceId: 3, pageSize: 20, pageIndex: 1 }; var url = this.router.urlFor(routeName, 1, 2, 3, 10, 1); console.log("inside generated url", url); For this router.js : this.route("scope", { path: '/:scopeId/:scopeData' }, function(){ this

问题 I'm running into a tough bug when trying to save a record with the LocalStorage Adapter that has a hasMany relationship (Using Ember CLI). What I'm trying to do is save a product to a bag when a user clicks on a "Add to Bag" button. I'm getting this error in my console: Uncaught TypeError: Cannot read property 'determineRelationshipType' of undefined Product Model: import DS from 'ember-data'; export default DS.Model.extend({ ... bag: DS.belongsTo('bag') }); Bag Model: import DS from 'ember

问题 It explains here how to observe items in an array with ember. My question is how can I determine the item being added/removed with this method? 回答1: You can use the addArrayObserver method to find items added/removed from an array. The code will look something like this that.get('content').addArrayObserver(this, { willChange: Ember.K, didChange: function(array, start, removeCount, addCount) { alert(array[start]); } }); More information can be found here. Here is a link to a working demo. 来源：

问题 I'm trying to learn ember.js and having a difficult time trying to make the connection between it all. I've gone through the tutorials provided on ember.js, but still a bit confused. The model contains the data that will be saved on the server. The controller has access to the model's data and can decorate it (add its on display data) and send that to the template itself. In the examples, they use the route class to actually get the data from the model. They associate the route with a model

问题 I have a click handler that needs to make several async calls, one after another. I've chosen to structure these calls using promises (RSVP, to be precise). Below, you can see the clickA handler, inside the controller (it's an Ember app, but the problem is more general, I think): App.SomeController = Ember.Controller.extend({ actions: { clickA: function() { var self = this; function startProcess() { return makeAjaxCall(url, { 'foo': self.get('foo') }); } function continueProcess(response) {
