Ember 2.1.0（CLI）＆Ember Data 2.1.0'belongsTo'使用EmbeddedRecordsMixin POST到API

Question

使用DS.EmbeddedRecordsMixin類使用RESTAdapter向API發佈新記錄。

我錯過了什麼？ Post中的'activity'字段仍然是'null' - 我嘗試了各種實現，但是從我能看到的下面應該工作。

串行器/ useractivity.js

export default DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, { 
    attrs: { 
    activity: { embedded: 'always' } 
    } 
}); 

型號/ useractivity.js

export default DS.Model.extend({ 
    activity: DS.belongsTo('activity', { async: true }), 
    // activity: DS.attr('string'), (using this works fine but I need the link) 
}); 

createRecord行動：

activitysave() { 
     this.store.createRecord('useractivity', { 
      activity: 11, 
      username: "ncole458", 
      activity_type: "physical", 
      activity_duration: "06:17:06", 
      activity_duration_repeats: 1, 
      activity_duration_weeks: 2, 
      activity_start: "2015-08-26", 
      complete_date: null, 
      activity_checkin: 1, 
      last_checkin: "2015-09-06", 
      delete: false, 
     }).save(); 
    } 

API帖子：

{"useractivity":{"activity":null}}

解決辦法如下，如果任何人有這方面的經驗，它應該仍然很好，因爲它應該像上面那樣工作。

export default DS.Model.extend({ 
    activity: DS.attr('string'), 
    activity_details: Ember.computed('activity', function() { 
     var activity_model = this.get("store").find("activity", this.get('activity')); 
     return activity_model; 
    }), 
});
