问题 I'm writing an action handler in route:application : actions: { changeFoo(foo) { // I want to change the fooId queryParam to foo.get('id') } } The problem is that the only documented ways I can find to change the query params are transitionTo('some.route', someModel, { queryParams: { ... } } and the replaceWith version of the same. But I'm in route:application , so I don't know the current route's name. That means I don't know what the first argument to transitionTo would be. Is there another

问题 I'm using Twitter Bootstrap and have a navbar with a regular link and a dropdown link. Using ember's link-to helper, the regular link automatically gets the "active" class when clicked, as do the menu items in the dropdown menu.

问题 So I have a view that implements fixed header by watching scroll event on the window. didInsertElement: function () { var self = this; $(window).on("scroll resize", function () { if (self.onWindowScroll) { Ember.run.throttle(self, 'onWindowScroll', 150); } }); }, onWindowScroll: function () { //do stuff }, willDestroyElement: function () { this.set('onWindowScroll', null); } This works but I was wondering if there is a cleaner approach for removing the logic attached to the scroll event.

Each record is DS.Model, say Client {{# each item in controller}} {{item.balance}} {{/each}} balance is a property of the Client model and a call to item.balance will fetch the property from the model directly. I want to apply some formatting to balance to display in a money format. The easy way to do this is to add a computed property, balanceMoney, to the Client object and do the formatting there: App

问题 Ember data expects my server to return the full object after each successful POST . However, my API only returns a kind of meta-object that contains the id . When Ember receives this object, the existing data in the record gets deleted except for the id . So for example, when I do this: var asset = App.Asset.store.createRecord('asset',{name: 'foo.ai', paths: ['/path/foo.ai', '/another/path/foo.ai'], type: 'ai', hash: '1234567890123456789012345678901234567890', datecreated: 'Sun, 12 Jan 2014
