问题描述
我有两个模型,MyModel和MyOptions。
I have two models, MyModel and MyOptions.
MyModel有一个myValue属性归属于('myOption)和myName('string')。
MyModel has a myValue property belongsTo('myOption), and myName('string').
在视图中,我有一个myName输入和一个选择,其中包含模型MyOptions的可能值。
In the view, I have an input for myName and a select with possible values of the model MyOptions.
当我选择一个新的相关行,我希望myModel是脏的。如果我更改了myName,myModel(正确)会变脏。
When I select a new related row, I expect myModel to be 'dirty'. If I change myName, myModel gets 'dirty' (correctly).
我做错了什么?
谢谢
window.App = Ember.Application.create();
App.ApplicationAdapter = DS.FixtureAdapter.extend();
App.IndexController = Ember.ObjectController.extend({
});
App.IndexRoute = Ember.Route.extend({
model: function() {
return Ember.RSVP.hash({
myModel: this.store.find('myModel', 1),
myOptions: this.store.find('myOption')
});
},
});
App.MyOption = DS.Model.extend({
name: DS.attr('name')
});
App.MyOption.FIXTURES = [
{ name: 'User a', id: 1 },
{ name: 'User b', id: 2 },
{ name: 'User c', id: 3 },
];
App.MyModel = DS.Model.extend({
myValue: DS.belongsTo('myOption'),
myName: DS.attr('string')
});
App.MyModel.FIXTURES = [
{
id: 1,
myValue: 2
}
];
<script type="text/x-handlebars" data-template-name="index">
<h1>Test</h1>
<lablel>My Value</label>{{input value=myModel.myValue.id}}
<lablel>My Name</label>{{input value=myModel.myName}}
{{view "select"
content=myOptions
selectionBinding=myModel.myValue
optionLabelPath="content.name"}}
{{myModel.isDirty}}
</script>
推荐答案
ember-data不能处理关系的肮脏,然而。您需要在用户空间中实现它。
ember-data doesn't handle dirtyness for relationships, yet. You would need to implement it in user-space.
