问题 I have been bumping my head concerning editing a child record that is already created. I am using thesame form partial for both creating and editing. I am able to create a child record successfully with that form partial, but if I click edit, for some reason, the edit form does not display or contain the just created record, the edit form is basically empty. To reproduce the error , don't add comments via the fixtureAdapter. If the record is in the comment fixtureAdapter you will see the

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 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 need to get the grand total price of all the objects returned from a JSON API. my idea is to create a controller and set a property on it. Then grab the model loop over each object and add to the predefined property that objects total price. Something like this: export default Ember.Controller.extend({ orderTotal: 0, getOrderTotal: function(){ var model = this.get('model'); model.forEach(function(c){ var order_total = this.get('orderTotal') * c.total_price; this.set('orderTotal', order

问题 I'm trying to generate ID's for a model. Ember documentation says that Ember automatically generates IDs for its models. But when I pass data to Firebase and try to display it, the IDs return undefined.
