问题 I've been Googling for a while now, but haven't found any good solution. The root of the problem is that my records aren't being set to isDirty when using this method: DS.JSONTransforms.object = { deserialize: function(serialized) { return Ember.isNone(serialized) ? {} : serialized; }, serialize: function(deserialized) { return Ember.isNone(deserialized) ? {} : deserialized; } } From what I gather this is an old method that apparently still works, since it handles the JSON objects I'm

问题 I have two models that are many to many. They're used on the first page of my app and I'm having trouble loading them. Both models only have a handful of items (<200) and I'd like to just load both models completely in one findAll request each. But as the first model gets loaded, Ember starts fetching the missing data for the second model, item by item. If I try to just load the models separately, I get an error and have to set {async:true} for the hasMany attr. For some reason though, Ember

问题 In my model, I have a queryParam status which is set to refreshModel true in my route. queryParams: { status: { refreshModel: true } } In my controller, this param is set to 'opened' by default : App.ConversationsController = Ember.ArrayController.extend({ queryParams: ['status'] status: 'opened' }); Everytime I set this param to something else, for example 'all', Ember-data resets it to 'opened' and makes two calls instead of one to my model hook, and this behavior has been observed with

问题 Unfortunately, ActiveModel::Serializers does not currently support validation errors, though they're scheduled for 1.0. Until then, I've got to hack a solution of my own. The big problem? I have no idea what format Ember Data's ActiveModelAdapter expects these errors to be in. I tried simply passing in the errors property, but Ember Data didn't pick up on it: class MySerializer < ActiveModel::Serializer attributes :errors end So what should I pass in instead? 回答1: I use this method to render

问题 I have a component which creates record for a specific model like this: export default Ember.Component.extend({ store: Ember.inject.service(), addRecord(account) { this.get('store').createRecord('update', { authUid: account.get('authUid'), service: account.get('platform') }); } }); I have another component that needs to observe changes done to a particular model (i.e. if records are added or deleted), and show them in that component. export default Ember.Component.extend({ store: Ember.inject

问题 I've been at this for a couple hours, fiddling with a number of different combinations to get this working. LO.List = DS.Model.extend({ name: DS.attr('string'), listItems: DS.hasMany('LO.ListItem', { embedded: true }) }); var lists = LO.store.findAll(LO.List), firstList = lists.objectAt(0), listItems = firstList.get('listItems'), firstListItemId = listItems.objectAt(0).get('id'); console.log(firstListItemId) // [object Object] http://jsfiddle.net/pjmorse/65eRS/ It seems that the 'embedded'

问题 store.findRecord('school', school_id, { include: [ 'students', 'students.records' ].join(',') Using the above code fetching school, students, students' records data in inital load. In the initial load, I don't need students.records (only listing students initially) Need student records only when clicking some button (All Students Performance - to display a performance chart) Is there any way to fetch associated records separately and link with the existing model I have sperate api endpoint

问题 I've successfully setup Ember CLI and Firebase and I'm attempting to bring some basic data into my templates. My 'title' and 'subtitle' data are apparent in the Ember Inspector, as well as my Firebase project dashboard. However, {{foo.title}} and {{foo.subtitle}} are coming back empty and undefined in the browser. Why is that? Here's my code: application.js (adapter) import DS from 'ember-data'; export default DS.FirebaseAdapter.extend({ firebase: new window.Firebase('https://<firebase

问题 This is my sample drop down <select name="newType" class="parts-select full-width-combo" onchange={{action "loadFilter" value="target.value" }}> <option value="" selected hidden >Select </option> {{#each model as |item|}} <option value="{{item.id}}">{{item.description}}</option> {{/each}} </select> from the relevant template action I wanted to set this selected item dynamically. As an example it default selected by "Select" and then based on some button click on that page and need to set my
