我已经从我找到的各种文档和示例中编译了这个示例,但是我还没有找到一个完整的示例,使用路由器和ember-data来简单地创建一个新记录,所以这是我的重点。
http://jsfiddle.net/dmazza/Hb6BQ/4/
我有一个人(DS.Model),带有firstName和lastName。
我有一个带索引和创建路径的路由器,其中创建表单出现在PeopleView的插座中。
我正在使用Ember.TextField绑定到使用App.Person.createRecord({})创建的新Person的属性,作为PersonCreateController的内容。
请注意,我有意在@wycats的推荐下为每个插座使用单独的控制器:https://github.com/emberjs/ember.js/issues/1050#issuecomment-6497907
我似乎一遍又一遍地遇到同样的问题。我尝试使用像App.Person.find()这样的方法,它会告诉我:
Uncaught TypeError: Cannot read property 'find' of undefined

随着在pre4中引入新的Ember路由器,我想我会更新这个答案。这是对我有用的(警告:CoffeeScript):
App.Router.map ->
@resource "posts", ->
@route "new"
App.PostsNewRoute = Ember.Route.extend
setupController: (controller, model) ->
controller.set 'content', {}
App.PostsNewController = Ember.ObjectController.extend
submitForm: (event) ->
App.Post.createRecord @content
@transitionToRoute 'posts.index'
App.PostsNewView = Ember.View.extend
controller: 'App.PostsNewController'
我的模板看起来像这样:
<script type="text/x-handlebars" data-template-name="posts/new">
<div class="row">
<div class="span12">
<form class="create-post">
<fieldset>
<legend>{{_ "Post"}}</legend>
<label>{{_ "Post Title"}}</label>
{{view Ember.TextField valueBinding="postTitle"}}
<!-- etc. etc. -->
</fieldset>
</form>
</div>
</div>
<div class="row">
<div class="span12 push-right">
<a class="btn btn-primary" {{action "submitForm"}}>{{_ "Save"}}</a>
{{#linkTo "posts.index" class="btn"}}{{_ "Cancel"}}{{/linkTo}}
</div>
</div>
</script>
我很想听听有关我的方法的评论。
