Question

可以通过表单字段操作用户。但我无法弄清楚如何保存（提交）它们。如果我更改lastName的{{1}}并单击保存按钮，我将收到以下错误：

User

点击保存按钮，我需要更改哪些保存（提交）记录？

的index.html

Uncaught Error: Attempted to handle event `save` on <App.User:ember309:1> while in state rootState.loaded.updated.uncommitted. Called with undefined

app.js

<script type="text/x-handlebars" data-template-name="users">
  <table class='table'>
      {{#each model}}
        <tr>
          <td>{{view Ember.TextField valueBinding='lastName'}}</td>
          {{#with this as model}}
            <td><button {{bindAttr class=":btn isDirty:btn-primary:disabled"}} {{action "save" target="model"}}>save</button></td>
          {{/with}}
        </tr>
      {{/each}}
  </table>
</script>

您可以像这样更改代码

<script type="text/x-handlebars" data-template-name="users">
  <table class='table'>
      {{#each model in controller}}
        <tr>
          <td>{{view Ember.TextField valueBinding='lastName'}}</td>
          <td><button {{bindAttr class=":btn isDirty:btn-primary:disabled"}} {{action "save"}}>save</button></td>
        </tr>
      {{/each}}
  </table>
</script>

使用each model in controller而非#with this as model

然后定义itemController

App.UsersController = Ember.ArrayController.extend({
  itemController: 'user'
});

这样您就可以使用save调用的UserController方法。

最后，请确保保存记录：

App.UserController = Ember.ObjectController.extend({
  save: function() {
    this.get('content.transaction').commit();
  }
})

如何触发提交/保存？
