问题 I'm using Ember-Data beta 3. My Ds.models are similar to the following: App.Item = DS.Model.extend({ itemName: DS.attr('string'), strategy: DS.belongsTo('strat') }); App.Strat = DS.Model.extend({ stratName: DS.attr('string'), items: DS.hasMany('item',{async:true}) }); Using Ember-data's RESTAdapter, I'm able to populate the model using data from my server.

问题 How could I prevent the itemView from being removed and re-rendered back in place when iterating over a controller's arrangedContent , if the observed model's property doesn't change value? Short version below, using a blog post App.Post as example model: Controller: sortProperties: ['createdAt'] Template: {{each arrangedContent}} {{title}} {{body}} {{/each}} objectAt(0).reload() causes the corresponding item to be removed and inserted back in the same place. The problem is that the itemView

问题 In my application, I am doing several find operations. All of them are working, except one, which is being rejected. For debugging purposes, I am sending the requests during startup of the application: preloadData : function () { SettingsApp.Node.find(); SettingsApp.Locator.find(); SettingsApp.Phonelocation.find(); SettingsApp.User.find(CNST.ME_FAKE_DOC_ID); SettingsApp.Company.find(CNST.MY_ORG_FAKE_DOC_ID); }, And this is how it looks in the console: As you can see, all requests are

问题 I'm working on a simple Tag model for one of my projects. I've implemented something similar in Angular, but I wanted to give it a try in Ember. The model code is below Tag = DS.Model.extend { name:DS.attr('string') user:DS.belongsTo('user') appliedTags:DS.hasMany('AppliedTag') obliterate:()-> #destory the associated applied tags this.get('appliedTags').forEach( (appliedTag)-> console.log(Ember.inspect(appliedTag)) appliedTag.destoryRecord() ) #destory the record this.destroyRecord() }

问题 I am experimenting with a Ember app using ember-data and a node.js backend serving data from MySQL using Sequelize.js. My problem: If I have a Comment model associated to a Post model through hasMany the expected JSON by ember-data looks like { "post": { "comment_ids": [1, 2, 3] } } What would be the best way to query / generate this JSON without expensive loops etc. using sequelize? The Comment model has a foreign key with the post_id. 回答1: I went for implementing it like: // include

问题 Using Ember 2.6.0 Have the following routes defined: Router.map(function() { this.route('brands'); this.route('brand', {path: '/brands/:brand_id'}); }); The model for brand is: export default Model.extend({ name: attr('string'), description: attr('string'), dateCreated: attr('date'), lastUpdated: attr('date'), regions: hasMany('region') }); And the model for region is: export default Model.extend({ name: attr('string'), dateCreated: attr('date'), lastUpdated: attr('date'), brand: belongsTo(

问题 I'm using Ember with ember-data and a rails api. I had a createRecord() and save() for the record that was working fine. The payload in the network tab for the post request to create the record in rails looks like: {data: {attributes: { foo: 'bar' } } .
