ember-data

问题 I'm having difficult saving a one-to-many relationship in ember data. I have a relationship like this: App.ParameterSet = DS.Model name: DS.attr("string") regions: DS.hasMany("App.Region") App.Region = DS.Model name: DS.attr("string") If I were to do something like this: parameterSet = App.ParameterSet.find(5) @transaction = @get("store").transaction() @transaction.add(parameterSet) region1 = App.Region.find(10) region2 = App.Region.find(11) parameterSet.set("name", "foo") parameterSet.get(

问题 I have an emberjs application backed by a nodejs server and mongodb . Currently my database is sending documents with an '_id' field. I have the followign code to force Ember to treat '_id' as the primary key : App.ApplicationSerializer = DS.RESTSerializer.extend({ primaryKey: '_id' }); On the other hand i have two models related by a 'hasMany' relationship as such: App.Player = DS.Model.extend({ name: DS.attr('string'), thumbLink: DS.attr('string'), activeGame: DS.belongsTo('game', { async:

问题 I receive JSON Api conform errors from the backend: { "errors": [ { "status": "400", "source": { "pointer": "/data/attributes/description" }, "detail": "This field may not be null." }, { "status": "400", "source": { "pointer": "/data/attributes/due-date" }, "detail": "This field may not be null." }, { "status": "400", "source": { "pointer": "/data/attributes/extra-comments" }, "detail": "This field may not be null." }, { "status": "400", "source": { "pointer": "/data/attributes/name" },

问题 I'm writing an Ember tutorial that I'd like to run on top of a very simple API I've created in Flask. PUT, DELETE, and GET requests made from ember-data behave as expected. The POST request throws an error and does not complete. The POST Ajax request is canceled before it's sent. This behavior is intermittent. If I set a breakpoint and follow it through the Ember internals then by the time I'm done, the request will often succeed. When running the API locally the error is thrown but the new

问题 How come Ember model store query doesn't update template model data and find does? // This doesn't update the template, when loading website no information is displayed but the data is loaded model: function() { var parentModel = this.modelFor("server.view"); return this.store.query("server", { server_address: parentModel.server_address }); } // This works without any problems model: function() { var parentModel = this.modelFor("server.view"); return this.store.find("server", 1); } 回答1: So I

问题 I am looking into how to show proper deletion error message in ember when there is an error coming back from the server. I looked at this topic and followed its suggestion: Ember Data delete fails, how to rollback My code is just like it, I return a 400 and my catch fires and logs, but nothing happens, when I pause it in the debugger though and try to rollback, I get Error: Assertion Failed: calling set on destroyed object So A) I cannot rollback B) the error is eaten normally. Here is my

问题 I am struggling to a Service's promised data in a Route. The problem occurs when I am transitioning to the Route at application init; that is, if I load the application, then transition, everything is fine, because the promise is already fulfilled, but if I hit browser reload on that Route, the offending lines won't run. The Service is: // services/lime-core.js import Ember from 'ember'; export default Ember.Service.extend({ store: Ember.inject.service(), resources: null, init() { this.set(

问题 I'm trying to learn ember but having a hard time finding out why my data from the backend is not showing up. I'm using Ember Data with mirage fixtures. The data is showing up. Only if I introduce simple relationships the data from those relationships is not showing up in my app. Is there a general way how to debug when you just get <!----> in your ember app? mirage/fixtures/contacts.js export default [ { id: 1, userName: "Barack Obama", profilePictureUrl: "/img/profilepics/barack.png",

问题 I'm using ember-data's fixtures adapter extensively to provide a lot of set-up data in my app. For one model ("Structure"), there is an array of embedded related objects ("Overlays"). When I load a Structure instance from the store, then query its overlays property, I get this error: Uncaught Error: assertion failed: Unable to find fixtures for model type App.Overlay Both models are defined as follows (with a few other fields/relationships removed for clarity): App.Structure = DS.Model.extend
