在ember-data升级后无法创建记录 [英] Cannot create record after ember-data upgrade

问题描述

在最新的ember-data 1.0发行版之后，创建记录时遇到了一些问题。我在发行说明中阅读 - https://github.com/emberjs/data/ blob / master / TRANSITION.md ：

  App.NewPostRoute = Ember.Route.extend（{
 model：function（）{
 return App.Post.createRecord（）; 
} 
}）; 
  

现在替换为：

  App.NewPostRoute = Ember.Route.extend（{
 model：function（）{
 return this.store.createRecord（'post'）; 
} 
}）; 
  

但是在我的控制器中，我无法弄清楚如何调用createRecord（）方法，如下所示：

  addNewTrip：function（）{
 var tripDeparature = this.get（tripDeparature）; 
 var tripArrival = this.get（tripArrival）; 
 var trips = App.Trips.createRecord（{
 tripDeparature：tripDeparature，
 tripArrival：tripArrival，
 isCompleted：false 
}）; 
 trip.save（）; 
 this.set（tripDeparture，）; 
 this.set（tripArrival，）; 
} 
  

它会抛出一个错误：...没有方法'createRecord'这是预计在新版本之后），但我无法弄清楚如何正确调用createRecord。非常感谢任何帮助。

解决方案

而不是 App.Trips.createRecord（parameters ...） 使用 this.store.createRecord（'tripps'，参数...）。

你的代码将成为：

  addNewTrip：function（）{
 var tripDeparature = this.get（tripDeparature ）; 
 var tripArrival = this.get（tripArrival）; 
 var trip = this.store.createRecord（'tripps'，{
 tripDeparature：tripDeparature，
 tripArrival：tripArrival，
 isCompleted：false 
}）; 
 trip.save（）; 
 this.set（tripDeparture，）; 
 this.set（tripArrival，）; 
} 
  

After the latest ember-data 1.0 release, I have had some problems creating records. I read in the release notes - https://github.com/emberjs/data/blob/master/TRANSITION.md that:

App.NewPostRoute = Ember.Route.extend({
  model: function() {
    return App.Post.createRecord();
  }
});

is now replaced with:

App.NewPostRoute = Ember.Route.extend({
  model: function() {
    return this.store.createRecord('post');
  }
});

However in my controller I cannot figure it out how to call the createRecord() method, as I have something like this:

addNewTrip:function() {
    var tripDeparature = this.get("tripDeparature");
    var tripArrival = this.get("tripArrival");
    var trips = App.Trips.createRecord({
         tripDeparature: tripDeparature,
         tripArrival:tripArrival,
         isCompleted:false
    });
    trip.save();
    this.set("tripDeparture","");
    this.set("tripArrival","");
}

And it throws an error: ...has no method 'createRecord' (which is expected after the new release), but I cannot figure it out how to call the createRecord correctly. Any help is greatly appreciated.

解决方案

Instead of App.Trips.createRecord(parameters ...) use this.store.createRecord('trips', parameters ...).

Your code will become:

addNewTrip:function() {
    var tripDeparature = this.get("tripDeparature");
    var tripArrival = this.get("tripArrival");
    var trip = this.store.createRecord('trips', {
         tripDeparature: tripDeparature,
         tripArrival:tripArrival,
         isCompleted:false
    });
    trip.save();
    this.set("tripDeparture","");
    this.set("tripArrival","");
}
