问题 I'm just starting to learn ember and am writing a simple app that reads from a database. I've gotten it to work with fixtures how I want and have just started making some progress reading from a database. Right now my problem is that I can't access children elements - I have a parent class that I am responding to with json through a serializer, and I am serving the children elements in the json request. However, I don't know where to go from here to get the parent class in ember to read and

问题 I am using Ember 2.12, there are two controllers - one for applicant and other for coapplicant for our application flow. When the user decides to delete the coapplicant, I am trying to get rid of its state (that unfortunately lives in the coapplicant controller instead of a separate data object). so i am trying to destroy the controller and then recreate it the next time the page loads. in the resetController state, I call this.destroy(); And in the routes/form.js page, in the setupController

问题 I have Esploreo.TE.Views.ItemView = Ember.View.extend({ elementId : "item", templateName : 'itemTemplate' }); and a template like <script type="text/x-handlebars" data-template-name="itemTemplate"> content of templat </script> and all works good.

In previous Ember versions it was possible to write the template code in the definition of view, like this: Esploreo.TE.Views.ItemView = Ember.View.extend({ elementId : "item", template: Em.Handlebars

问题 Trying to wrap my head around how to efficiently model and code a "saved items" list for logged-in users. I want the user to be able to click "save item" from a product page, and it will add the item to a list kept in their user profile that has its own route that displays their items and allows them to manage the list. On that route, anytime there are changes to the list (like, item is removed), it should refresh to reflect the changes. I'd think the user model would look something like this

问题 I have a component with an empty Ember.Component.extend(); and a template. When I delete the js file, the component template still works and renders, but as a view instead of a component. Since the template is in "templates/components/" and Ember can find it and render it, shouldn't Ember be smart enough to render it as a component and not a view? Or is this expected behavior? 来源： https://stackoverflow.com/questions/37846577/ember-js-should-component-templates-turn-into-views-when-the-js-file
