ember-data

问题 I would like to use my emberdata as data for creating objects within d3. I try to convert the items from the controllers model into new javascript objects and giving this new array to d3 data. here is the code App.GraphicsView = Ember.View.extend( { didInsertElement: function() { var svg = d3.select("#svg"); var data = this.get('controller').get('model').get('content'); var newData = []; for(var i = 0; i < data.length; i++) { newData.push(data[i]); } var graphics = svg.selectAll("rect") .data

问题 I'm having the following problem. In my app I have a screen to make a new Site . But when I save the new site via an action on the controller, the languages -property isn't sent with the POST -request to the server.

问题 I'm ember.js newbie and facing daily problems :-) Today's problem is my server backend doesn't support sideloading . (If I understood 'sideload' right, it is server returns related models at once with multiple JSON root) for example, my server only returns below per request: for /api/v1/posts.json { posts: [{ id: 91, title: "ember.js" }, { id: 81, title: "ember-data.js" }] } for /api/v1/comments.json { comments: [{ id: 928, postId: 91, }, { id: 927, postId: 92, }] } When I load post model, go

问题 I've got a model called "Membership" that has a string attribute "inviteToken" which I would like to use as my primary key. I've created the following serializer, but cannot get it to pick up the primary key from the JSON. app/serializers/membership.js: import DS from 'ember-data'; export default DS.JSONAPISerializer.extend({ primaryKey: 'invite-token' // also tried 'inviteToken' }); The specific error I'm getting is: Error while processing route: invitations.show Assertion Failed: You must

问题 it's a common pattern to createRecord in the model hook when user enters the route. Sometimes those records remain unused, and they pops up in certain conditions, i.e. in peekAll query, although that is unwanted.

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 2 years ago . I'm an experienced Ember.js developer.

问题 I have two models in ember.js with a one-to-may relationship. Now I want to create a new child object and need to assign an associated parent object. I can't figure out how to do this. My models are defined with the following code: model of parent-object import DS from 'ember-data'; export default DS.Model.extend({ name: DS.attr('string'), children: DS.hasMany('child') }); model of child-object import DS from 'ember-data'; export default DS.Model.extend({ name: DS.attr('string'), parent: DS
