全面披露:我是 Ember 新手。
我已经启动了一个应用程序，当用户单击下一个按钮时，他们会创建客户模型的实例，并将该模型保存到本地存储中。在下一页上，我希望名字和姓氏都预先填充文本输入。我试图遵循 intro video但我遇到了一个问题。看来我正在创建对象，然后将其成功存储在本地存储中，但是当用户转换到下一页时，找不到模型。这是我的代码:

还有我的 app.js:
App = Ember.Application.create();
App.store = DS.Store.create({
revision: 12,
adapter: DS.LSAdapter.extend()
});
App.Router.map(function() {
// put your routes here
this.route("customer", { path: "/customer" });
this.route("wsnum", {path: "/wsnum"});
});
App.IndexRoute = Ember.Route.extend({
});
App.IndexController = Ember.Controller.extend({
create: function(){
var customer = App.Customer.createRecord({
first:"ron",
last:"testing"
});
console.log('Before the save');
customer.save();
console.log(customer.get('first'));
this.transitionToRoute('customer');
}
});
App.CustomerRoute = Ember.Route.extend({
model: function() {
var customer = App.Customer.find();
console.log(customer.get('first'));
return customer;
}
});
App.WsnumRoute = Ember.Route.extend({
});
var attr = DS.attr;
App.Customer = DS.Model.extend({
first: attr('string'),
last: attr('string')
});
这是一个working example 。有什么想法吗？
最佳答案
在App.CustomerRoute.model()中，这一行:
var customer = App.Customer.find();
将 customer 变量设置为 find() 的结果。 find() 返回所有客户记录的数组。因此，当您在数组上调用 get('first') 时，它是未定义的，因为客户数组没有属性 first。
还有路线
this.route("customer", { path: "/customer" });
可能应该是:
this.route("customer", { path: "/customer/:customer_id" });
因为它似乎是为了显示一个客户而不是他们的列表。
经过此更改，根本不需要 CustomerRoute。所以应用程序看起来像:
App = Ember.Application.create();
App.store = DS.Store.create({
revision: 12,
adapter: DS.LSAdapter.extend()
});
App.Router.map(function() {
this.route("customer", { path: "/customer/:customer_id" });
this.route("wsnum", {path: "/wsnum"});
});
App.IndexController = Ember.Controller.extend({
create: function(){
var controller = this;
var customer = App.Customer.createRecord({
first:"ron",
last:"harmon"
});
customer.save().then(function() {
controller.transitionTo('customer', customer);
});
}
});
var attr = DS.attr;
App.Customer = DS.Model.extend({
first: attr('string'),
last: attr('string')
});
