有谁知道如何显示来自服务器的数据，现在我一直在像这样的基本 Handlebars 中显示相关模型
{{
view Ember.Select
prompt="Organization"
contentBinding="organizations"
optionValuePath="content.id"
optionLabelPath="content.name"
selectionBinding="selectedOrganization"
}}
但是我需要创建一个有多种形式的...我使用 View 复制吗？ 使用 View 是正确的道路吗？!
{{#each view.anotherField}}
{{view Ember.TextField value=view.name}}
{{/each}}
这是我的表单的输出，你可以看到组织表单被加倍 JSbin http://jsbin.com/efeReDer/7/edit
今天我想出了这个...:D 有点达到目的吗？看起来很难看 <强> http://emberjs.jsbin.com/acUCocu/6/edit
基本上我做了一个空模型，然后每个循环。 在操作中我“store.create”.empty记录到它。 告诉我你对此的想法:) 还有没有办法让这些字段独立？当输入更改时，无需更改其内容。 干杯，

最佳答案
在这里你可以找到一个我认为你要问的例子

尝试将与应用程序模型相关的实体与其显示方式分开。创建了一个 ember 类 App.Person 来保存来自服务器的数据。我没有使用 ember-data，但如果需要，可以很容易地用 ember-data 表示法替换类，并将虚拟 ajax 调用替换为相应的存储调用等。
App = Ember.Application.create();
App.Router.map(function() {
this.route("persons");
});
App.IndexRoute = Ember.Route.extend({
beforeModel: function() {
this.transitionTo("persons");
}
});
App.PersonsRoute = Ember.Route.extend({
model:function(){
return $.ajax({url:"/"}).then(function(){/*in url it is required to place the actual server address that will return data e.g. from a rest web service*/
/*let's imagine that the following data has been returned from the server*/
/*i.e. two Person entities have already been stored to the server and now are retrieved to display*/
var personsData = [];
var person1 = App.Person.create({id:1,fname:"Person1",lname:"First",genderId:2});
var person2 = App.Person.create({id:2,fname:"Person2",lname:"Second",genderId:1});
personsData.pushObject(person1);
personsData.pushObject(person2);
return personsData;
});
},
setupController:function(controller,model){
/*this could also be retrieved from server*/
/*let's mimic a call*/
$.ajax({url:"/",success:function(){
/*This will run async but ember's binding will preper everything.If this is not acceptable, then initialization of lists' values/dictionary values can take place in any earlier phase of the app. */
var gendersData = [];
gendersData.pushObject(App.Gender.create({id:1,type:"male"}));
gendersData.pushObject(App.Gender.create({id:2,type:"female"}));
controller.set("genders",gendersData);
model.forEach(function(person){
person.set("gender",gendersData.findBy("id",person.get("genderId")));
});
}});
controller.set("model",model);
}
});
App.PersonsController = Ember.ArrayController.extend({
genders:[],
actions:{
addPerson:function(){
this.get("model").pushObject(App.Person.create({id:Date.now(),fname:"",lname:""}));
},
print:function(){
console.log(this.get("model"));
}
}
});
App.PersonFormView = Ember.View.extend({
templateName:"personForm",
/*layoutName:"simple-row"*/
layoutName:"collapsible-row"
});
App.Person = Ember.Object.extend({
id:null,
fname:"",
lname:"",
gender:null
});
App.Gender = Ember.Object.extend({
id:null,
type:null
});
html/hbs
创建了一个 View ，负责处理每个 App.Person 实例的渲染方式。例如，partial 和 layouts 已用于适应引导样式，因为我注意到您在示例中使用了一些。
