从服务器到视图的-retrieving数据？
从服务器到视图的-retrieving数据？
提问于 2014-01-03 09:16:44
有没有人碰巧知道如何显示来自服务器的数据，现在我已经在基本的把手中显示了相关的模型，像这样
{{
view Ember.Select
prompt="Organization"
contentBinding="organizations"
optionValuePath="content.id"
optionLabelPath="content.name"
selectionBinding="selectedOrganization"
}}但我需要创造一个有很多形式的..。什么是复制使用视图？正在使用视图，甚至正确的路径去 ?！
{{#each view.anotherField}}
{{view Ember.TextField value=view.name}}
{{/each}}
这里是我的表单的输出，你可以看到组织形式是加倍的JSbin http://jsbin.com/efeReDer/7/edit
今天我想到了这个..。:D Kinda起作用了吗？看上去很丑，http://emberjs.jsbin.com/acUCocu/6/edit
基本上，我做了一个空模型，然后每个循环。在行动上我"store.create".empty对它的记录。请告诉我你对此的想法:)是否也有办法使这些领域变得坚不可摧？当输入被更改时，不需要全部更改它们的内容。干杯,

在这里，你可以找到一个值得研究的例子，我认为你在问什么。

试图将与应用程序模型相关的实体与如何成为displayed.Created (一个将保存来自服务器的数据的成员类App.Person )分开。我没有使用成员-数据，但它很容易取代类的成员数据表示法和虚拟ajax调用与各自的存储调用等，如果需要。
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
创建一个视图，该视图负责每个App.Person实例的呈现方式。例如，partial和layouts已经被用来容纳引导样式，正如我注意到您在示例中使用了一些。
