Setting a belongsTo Relationship on a Dirty Object in Ember.js

问题

I'm using Ember.js 1.0 and Ember-Data 1.0.0beta2. I have a couple of related models:

Whistlr.Upload = DS.Model.extend
  organizations: DS.hasMany('organization')

Whistlr.Organization = DS.Model.extend
  upload: DS.belongsTo('upload')

The user creates the Upload within the Organization form via Jquery File Upload. In the success callback, I set the relationship like so:

upload = @get('parentView').get('controller').store.createRecord('upload', response.upload)
@get('parentView').get('controller').set('upload', upload)

Unfortunately, it's getting set to null. Is this because I'm trying to set the relationship while both the Organization and Upload instances are dirty?

回答1:

You're setting the upload on the controller instead of on a model. You probably want to do :

@get('parentView').get('controller.model').set('upload', upload)
