问题 Currently I have a form called a "form A", I've created a number of views for this form, an edit, create and list. I want to be able to create a form called "form B", that will pull through "form A's ID" as a parent ID. To enable me to have a list of all form B under a "form A" (essential a one to many relationship). So at the moment under my list for "form A" I have this link for each item: {{#link-to 'form-a.form-b.listing' form-a.id}} <!--Link to a controller --> <span class="btn btn

问题 I like to access a controller property within Ember Data Transform. Is there anyway how to do that? Perhaps a few words to my use case. I like to create a custom attribute 'encryptedStrings' and use DS.Transform to encrypt / decrypt the string with a given key by using Stanford Javascript Crypto Library. The key should by part a query param in the uri. get method is defined in DS.Transform but I did not get further. Here the relevant parts of the code: App.EncryptedStringTransform = DS

问题 I am using ember data to get data from a remote server.

Receiving end does not exist. The URL I'm trying to open is: /#/track/85 This is the relevant code: Shoutzor = Ember.Application.create(); Shoutzor.ApplicationAdapter = DS.RESTAdapter.extend({

问题 I have classic multimodel form: a transport document that has many transport_document_rows, as stated in my MODELS: App.TransportDocument = DS.Model.extend number: DS.attr 'string' date: DS.attr 'string' transportDocumentRows: DS.hasMany('App.TransportDocumentRow') App.TransportDocumentRow = DS.Model.extend productName: DS.attr 'string' quantity: DS.attr 'string' transportDocument: DS.belongsTo('App.TransportDocument') I write in console this script: a = App.Invoice.createRecord(); a.get(

问题 I have a list of product-tag that I fetch for my model. Route: model: function() { return { product_tags: this.store.find('product-tag', {merchant: merchId}) } } I have a component that adds tags to the model, however when after I create the record and push it into the model (as suggested on other posts) my UI still isn't updating. addTag: function(name) { tag = this.store.createRecord('product-tag', { name: name }); this.model.product_tags.toArray().addObject(tag); tag.save(); } //model

问题 I'm trying to implement a full scale friending system with Ember (with friend requests that can be accepted or rejected, the ability to cancel friend requests, and unfriending). In order to do this, I have my Rails backend pass three different friendship arrays via JSON to ember, which are captured in the following ember models (extraneous stuff removed): App.User = DS.Model.extend name: DS.attr('string') friendships: DS.hasMany('friendship', { inverse: 'user' }) requestedFriendships: DS

问题 I'm working on a shared library that has internal Ember Data Models that are used by the calling application. However, those DS.Model objects from the library don't find their way into the store for the calling application. library.js DS.SharedLibrary.User = DS.Model.extend({}); DS.SharedLibrary.BaseModel = DS.Model.extend({ createdBy: DS.belongsTo('DS.SharedLibrary.User') }); app.js App.MyModel = DS.SharedLibrary.BaseModel.extend({ customField: DS.attr() }); However, when the adapter goes to

问题 Page has a polymorphic 1:1 relationship with a model called PageContent. PageContent has two subtypes (TextOnly and Video). I want to be able to able to do a findAll for "page" and get all of the content back. What am I doing wrong? JSBin 回答1: This seems to work: http://jsbin.com/names/1/edit Only wrong thing I could see is the App.Page.FIXTURES. It should be: App.Page.FIXTURES = [ { id: 1, title: "Introduction", pageContent: 1, pageContentType: "textOnly" },{ id: 2, title: "Summary",
