如何将模型传递给从Ember 1.6中路由呈现的模板 [英] how to pass a model to a template rendered from a route in Ember 1.6
问题描述
我正在尝试在路由中呈现的模板中设置模型。该模型正在通过模板调用正确捕获:
{{#each itemController =user}}
< div {{bind-attr class =isExpanded:expanded}}>
< div>< button {{actionsayHellothis}}> {{first_name}} {{last_name}}< / button>< / div>
和我的路线:
Newkonf.UsersRoute = Ember.Route.extend({
isExpanded:false,
actions:{
sayHello:function(myModel){
alert('first name:'+ myModel.first_name); //< - 这个工程
// this.render('edit-user',{model:myModel});< ; - 不工作,但不确定,因为这导致我susupec
//它可能https://github.com/emberjs/ember.js/issues/1820
// this.set( 'model',myModel});< - 不工作
this.render('edit-user');
}
}
}
手柄是:
要在这里编辑用户名:{{first_name}}

是的,我可以在UsersRoute中更新消息,它会相应更新,虽然我指出UserController会使UserRoute优先,但是我gue ss不。
这是我的路由器:
Newkonf.Router .map(function(){
// this.resource('posts');
this.route('about',{path:'/ about'});
this.resource('users',{path:'/ users'});
});
thx任何帮助

不得不这样做我的modal.js.hbs:
{{model.first_name}}
因为这没有' t $ {
$ b $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ c>
不知道为什么。
这是我的路线
Newkonf.ApplicationRoute = Ember.Route.extend({
actions:{
somePlace:function(item){
alert('这里我在somePlace:'+ item.last_name); //< - 这个工程
var modalController = this.controllerFor('modal');
modalController.set ('model',item);
var myjt = modalController.get('model');
console.log('my value:'+ myjt.first_name); //< - 这个工程
this.render('modal',{
into:'application',
outlet:'modal3 ,
控制器:modalController
});
}
}
});
,没有控制器
在特定插座上进行渲染需要将该插座命名,并且当您尝试呈现插槽时,该插座将被查看。
在模态的情况下,将其存在于应用程序模板中通常是一个不错的选择,因为应用程序始终在视图中。
actions:{
openModal:function(item){
var modalController = this.controllerFor('modal');
modalController.set('model',item);
this.render('modal',{// template
into:'application',// template the outlet lives in
outlet:'modal',// the outlet's name
控制器:modalController //控制器使用
});
}
}
App.ModalController = Em.ObjectController.extend();
在上述情况下,我正在渲染模板 modal
,进入应用程序
,使用名为 modal的插件
( {{outlet'modal '}}
),我创建了一个控制器来备份我呈现的模板。在这个过程中,我将模型设置在控制器上,这将在模板中使用。

I'm am trying to set a model in a rendered template from a route. The model is being captured correctly via the template call:
{{#each itemController="user"}}
<div {{bind-attr class="isExpanded:expanded"}}>
<div><button {{action "sayHello" this}}>{{first_name}} {{last_name}}</button></div>
and my Route:
Newkonf.UsersRoute = Ember.Route.extend({
isExpanded: false,
actions: {
sayHello: function(myModel){
alert('first name: ' + myModel.first_name); // <- this works
// this.render('edit-user', {model: myModel}); <- doesn't work but not sure since this leads me to susupec
// it might https://github.com/emberjs/ember.js/issues/1820
// this.set('model', myModel}); <- doesn't work
this.render('edit-user');
}
}
}
the handlebars is:
going to edit user here first name: {{first_name}}
edit 1
Yes, I can update the message in UsersRoute and it will update accordingly. I kinda though since I specified UserController that it would cause UserRoute to take precedence but I guess not.
Here is my router:
Newkonf.Router.map(function() {
// this.resource('posts');
this.route('about', { path: '/about'});
this.resource('users', { path: '/users'});
});
thx for any help

had to do my modal.js.hbs like this:
within modal for you:
{{model.first_name}}
because this didn't work:
within modal for you:
{{first_name}}
and not sure why.
here's my Route
Newkonf.ApplicationRoute = Ember.Route.extend({
actions:{
somePlace: function(item){
alert('here i am in somePlace: ' + item.last_name); // <- this works
var modalController = this.controllerFor('modal');
modalController.set('model', item);
var myjt=modalController.get('model');
console.log('my value:' + myjt.first_name); // <- this works
this.render('modal', {
into: 'application',
outlet: 'modal3',
controller: modalController
});
}
}
});
and there is no controller
Rendering to a particular outlet requires both the outlet be named, and the outlet to be in view when you attempt to render to it.
In the case of a modal, having it live in the application template is generally a good choice since the application is always in view.
actions: {
openModal: function(item){
var modalController = this.controllerFor('modal');
modalController.set('model', item);
this.render('modal', { // template
into: 'application', // template the outlet lives in
outlet: 'modal', // the outlet's name
controller: modalController // the controller to use
});
}
}
App.ModalController = Em.ObjectController.extend();
In the case above I'm rendering the template modal
, into application
, using the outlet named modal
( {{outlet 'modal'}}
) and I created a controller to back the template I'm rendering. In the process I set the model on the controller, which would be used in the template.
