with Ember Data, how do you call commit?

问题

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

I have my store set up like so:

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

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", "");
  }
});

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?

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", "");
  }
});

I've placed a simplified, working example using DS.FixtureAdapter here: http://jsbin.com/ugipap/1/edit

Done, right?

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.
