ember.js

问题 Anybody has any ideas or references on how to implement a data persistence layer that uses both a localStorage and a REST remote storage: The data of a certain client is stored with localStorage (using an ember-data indexedDB adapter). The locally stored data is synced with the remote server (using ember-data RESTadapter). The server gathers all data from clients. Using mathematical sets notation: Server = Client1 ∪ Client2 ∪ ... ∪ ClientN where, in general, any record may not be unique to a

问题 How do we check for a value equality in ember.js's If-block helper? {{#if person=="John"}} How do we perform above in handlebars? 回答1: The {{#if}} helper can only test for properties, not arbitrary expressions. The best thing to do in cases like this is therefore to write a property computing whatever conditional you want to test for. personIsJohn: function() { return this.get('person') === 'John'; }.property('person') Then do {{#if personIsJohn}} . Note: If you find this too limiting, you

问题 I am very new at Ember/ED/EmberFire so apologies if this is a trivial question. I am able to save records to Firebase but I am unable to specify relationships to those records in my controller. I am using DEBUG: Ember : 1.10.0 DEBUG: Ember Data : 1.0.0-beta.12 DEBUG: Firebase : 2.2.3 DEBUG: EmberFire : 1.4.3 DEBUG: jQuery : 1.11.2 I have a model as such: var Patient = DS.Model.extend({ lastName: DS.attr('string'), firstName: DS.attr('string'), encounters: DS.hasMany('encounter', {async: true}

问题 Using the last version of ember-js and ember-data, I got an issue when deleting a record. My route : App.ListContactsRoute = Em.Route.extend({ model: function() { App.Contact.find(); }, setupController: function(controller, model) { controller.set('contacts', model); } }); App.EditContactRoute = Em.Route.extend({ setupController: function(controller, model) { this.transaction = controller.get('store').transaction(); this.transaction.add(model); controller.set('content', model); controller.set

问题 I created this simple JsBin to demonstrate what I'm after. JSBIN I have some Fixture data and each item in it has a boolean property called isFavourite. The indexRoute just displays all the available data along with a second section that displays the items that are favourites. Each item also has a class binding to this isFavourite property. If it's a favourite, it'll have red text. There is a second route called dashboard which only displays a subset of the data from the store. There is also

问题 Do action handlers not work directly on view instances? Instead of attaching an action handler within the view, I want to attach it directly on the entire view itself. Sample jsFiddle: http://jsfiddle.net/t3wdG/ UPDATE: My goal is to delegate to specific functions (undo, redo in this case) on the parentView. The reason I have the buttonView is because on click on each button, I want to do something to it, for example add a css class to it. So in effect, I want all my buttons to add a class to

问题 My background is in old-school web development and LAMP stack development mixed with Linux server administration. Meaning I can code HTML, PHP, CSS and JavsScript—as well as manage a Linux server—with ease. But have decided I need to be a bit “modern” as far as web client side technology goes and am teaching myself EmberJS on my Mac OS X 10.9.5 machine. Core versions are as follows: Ember CLI version: 1.13.12 Node JS version: 4.2.2 NPM (Node Package Manager) version: 2.14.10 Watchman: 4.1.0

问题 I have the following problem: A form with a select field for selecting the category of a post. Let's say the post has category 100. In Ember inspector, this is shown as follows: category: <App.Category:ember708:100> When I save the post (via Ember Data 1.0.0 beta 2), the category suddenly changes to: category: 100 And the value is no longer selected in the select list. It is cleared. Code to save: post.save().then( function () { alert("Save OK"); } ) Any idea in which direction I need to

问题 Let's say I have 2 independent set of controllers/models: Dog and Cat . Now, whenever I create new Cat record (or delete existing one) I want Dog controller to observe for creation/deletion of the record and when new Cat record is created I want it to fire some action (for example console.log('Bark!') ). I don't want to send action from Cat controller to Dog controller directly in this case; I want Dog controller to be responsible for itself. In case it is possible, is there any way to tell
