在带有动态分段路由器v2的模型中使用ajax加载的最佳方法是什么 [英] What is the best way to use ajax loading for model with dynamic segments router v2
问题描述
我正在面对动态细分路由器v2的问题。
是js的链接 http://jsfiddle.net/q9zvU/5/
I'm facing the problem with dynamic segments router v2. here is the link for js "http://jsfiddle.net/q9zvU/5/".
var App = Ember.Application.create();
App.deferReadiness();
App.ApplicationView = Ember.View.extend({
templateName: 'campaign-app'
})
App.Router.map(function(match) {
this.route('campaigns', {path: '/:type'})
})
App.CampaignsRoute = Ember.Route.extend({
model: function() {
alert('called model method');
var data;
$.ajax({
url: '/echo/json/',
async: false,
data: {
json: JSON.encode([{
name: 'Campaign 1',
type: 'scheduled'
}, {
name: 'Campaign 2',
type: 'scheduled'
}, {
name: 'Campaign 2',
type: 'draft'
}])
},
dataType: 'json',
success: function(json) {
alert(JSON.stringify(json));
data = json;
}
})
return data;
},
renderTemplate: function() {
this.render({outlet: 'campaigns'});
}
})
App.CampaignsView = Ember.CollectionView.extend({
itemViewClass: Ember.View.extend({
templateName: 'campaigns'
})
})
App.advanceReadiness();
路线的模型方法不是通过linkTo和transitionTo调用的。 (在ember的文档中明确说明)。
但就我而言,我确实需要一个点来从路由中的ajax请求加载数据。
The model method of route isn't calling with linkTo and transitionTo. (It is clearly stated in ember's doc). But for my case, I really need to have a point to load the data from ajax request in route.

推荐答案
Ember模型挂钩上的文档:
Ember Documentation on the model hook:
您可以实现一个钩子来将URL转换为此
路由的模型。
"A hook you can implement to convert the URL into the model for this route."
因此,模型挂钩只是在页面刷新时调用。但这使很多人感到困惑:-)。因此,在这种情况下,这不是正确的选择。我认为您应该在这种情况下使用setupController挂钩。试试这个:
So the model hook is just called on page refresh. But this confuses a lot of people :-). So, this is not the right hook in this case. I think you should use the setupController hook for this case. Try this:
App.CampaignsRoute = Ember.Route.extend({
setupController: function(controller) {
alert('called setupController method');
var data;
$.ajax({
url: '/echo/json/',
async: false,
data: {
json: JSON.encode([{
name: 'Campaign 1',
type: 'scheduled'
}, {
name: 'Campaign 2',
type: 'scheduled'
}, {
name: 'Campaign 2',
type: 'draft'
}])
},
dataType: 'json',
success: function(json) {
alert(JSON.stringify(json));
data = json;
}
});
controller.set("model",data);
}
});
一些额外的说明:您似乎没有包裹您的包裹很尴尬Ember.Object中的对象。通常,您不使用普通的JS对象。
A little extra remark: It seems awkward that you do not wrap your objects in an Ember.Object. Normally you do not work on ordinary JS objects.
