How to cache random results using Ember data?

By : Dragos Serghie

should help you out I know this isn't exactly what you are asking for, but I'd have the backend provide the random 15 items, and use the following code.
code :
export default Route.extend({
  async model() {
    let response = await fetch('/api/whatever-endpoint');
    let json = await response.json();

    return { items: json };
export default Controller.extend({
  searchText: '',

  actions: {
    didSubmitForm() {
      // do something here on submit
      // fetch again? add item to list?
      // depends!
    search() {
      let items = this.model.items;
      let randomId = items[Math.floor(Math.random() * items.length].id

      $('#searchbar-form').submit(); // or call a native function here

How about a walk through of the lifecycle of ember/ember-data objects. Or tips/hints for debugging Ember.js and Ember-Da

With these it helps First, is that you will want to use the debug version of ember, not the minified production version. This will give you better ember information in the console.
Secondly, the thing that has been greatly helpful for me, is to add in debugging within all my events in my routes, views, and controllers.
code :
window.App = Ember.Application.create({

    debugMode: false,

    log: function(message, location, data) {
      if (this.debugMode) {
        if (data != null) {
          if (typeof data === 'object') {
            data = Ember.inspect(data);
          console.log('DEBUG: ' + this.appName + ' : ' + location + ' : ' + message);
          return console.log('DEBUG: ' + this.appName + ' : (continued) data: ' + data);
        } else {
          return console.log('DEBUG: ' + this.appName + ' : ' + location + ' : ' + message);
App.ProfileController = Ember.ObjectController.extend({

  setProfile: function() {
    App.log("setting current user's profile", 'App.ProfileController.setProfile', App.currentUser);
  //do other stuff with the profile
App.EventController = Ember.ObjectController.extend({
  init: function() {
    App.log('initializing event controller', 'App.EventController.init');
    return this.set('isLoading', false);
DEBUG: My App Name : App.ApplicationController : application controller initializing
DEBUG: My App Name : App.ApplicationRoute.setupController : setupController called
DEBUG: My App Name : (continued) data: {target: <App.Router:ember249>, namespace: App, container: [object Object], _debugContainerKey: 
DEBUG: My App Name : App.accountController.setCurrentUser : setting applications currentUser object
DEBUG: My App Name : (continued) data: {"id":3,"username":"bob","firstName":"Bob","lastName":"W","updatedAt":"2013-04-16T06:29:39.731Z"}
DEBUG: My App Name : App.EventController.init : initializing event controller
DEBUG: My App Name : App.EventRoute.setupController : setupController called
DEBUG: My App Name : (continued) data: {target: <App.Router:ember249>, namespace: App, container: [object Object], _debugContainerKey: controller:event, _childContainers: [object Object], isLoading: false} 

Ember-Data .find() vs .all() - how to control cache?

By : Mike River

help you fix your problem I was told that in order to not make a request all the time, one can use .all() method to load data that is kept in the store. But how does Ember deal with cache? I have a couple of questions. , So will start by answering question from your comment:
code :
App.ApplicationRoute = Ember.Route.extend({
  model: function({
    return App.Post.find();

Cache data from external api with rails or ember?

By : Randy York
Date : March 29 2020, 07:55 AM
I think the issue was by ths following , You should create a DS.Model for 'contact' and use a has_many on Contacts and Payments model. Then, you could specify 'async: true' like
code :
DS.hasMany('contact', {async: true}),

How to ensure Ember Data remove the cache from store?

By : Jack Long
Date : March 29 2020, 07:55 AM
I hope this helps . Turns out I was using a mixin in my route, and within that mixin the model function actually created a new array using this.store.peekAll().filter() which obviously won't be updated as the array now points to another object /facepalm
