使用Ember Data，你如何调用commit？ [英] with Ember Data, how do you call commit?

问题描述

我正在尝试使用所有最后的路线和数据填充垃圾来构建一个简单的Todo列表。您可以找到我的完整的回购 here

I am trying to build a simple Todo List using all the last routes and data stuff for ember. You can find my full repo here

我有我的商店设置如下：

I have my store set up like so:

EmberTodo.Store = DS.Store.extend({
  revision: 11,
  adapter: DS.RESTAdapter.create({bulkCommit: false})
});

给我麻烦的代码行来自于：

The line of code that is giving me trouble comes from here:

EmberTodo.CreateItemView = Ember.TextField.extend({
  insertNewline: function() {
    EmberTodo.Item.createRecord({description: this.get('value')});
    this.set("value", "");
  }
});

根据我的理解，调用 createRecord 不要创建记录，而是需要在某个地方调用 commit（）。但是，我无法弄明白哪里。任何人都有什么想法？

From what I understand, calling createRecord doesn't create the record, but instead I need to call commit() somewhere. However, I cannot figure out where. Anyone have any ideas?

当然可以。为了使这个工作尽可能小的

Sure. To get this working with the smallest possible

EmberTodo.CreateItemView = Ember.TextField.extend({
  insertNewline: function() {
    item = EmberTodo.Item.createRecord({description: this.get('value')});
    item.get('transaction').commit();
    this.set("value", "");
  }
});

我已经使用DS.FixtureAdapter放置了一个简化的工作示例： http://jsbin.com/ugipap/1/edit

完成，对吗？

Done, right?

Kinda。事实上，你真的不希望从一个角度来做这样的事情。考虑重构将逻辑转移到控制器层，或者可能根据情况将路由器移动。

Kinda. Thing is, you really don't want to be doing this kinda thing from within a view. Consider refactoring to move this logic into the controller layer, or possibly the router depending on the situation.
