Ember数据剥离具有许多关系

Question

我有一个可怕的时间，但我有一个控制器上的以下动作:

saveOrganization: function() {  
  var org = this.get('model');
  var users = org.get('users').then(function() {
    console.log(org); //users are a part of org
    org.save(); //users are not sent to server
  });
}

和相关的组织模型:

export default DS.Model.extend({
  createdAt: DS.attr('date'),
  updatedAt: DS.attr('date'),
  name: DS.attr('string'),
  address: DS.attr('string'),
  city: DS.attr('string'),
  state: DS.attr('string'),
  zip: DS.attr('string'),
  users: DS.hasMany('user',{async:true}),
  totalUsers: function() {
    return this.get('users').get('length');
  }.property('users.@each')
});

和关联的用户模型:

export default DS.Model.extend({
    createdAt: DS.attr('date'),
    updatedAt: DS.attr('date'),
    name: DS.attr('string'),
    email: DS.attr('string'),
    bio: DS.attr('string'),
    picture: DS.attr('string'),
    organization: DS.belongsTo('organization'),
    type: DS.attr('string'),
    username: DS.attr('string'),
    password: DS.attr('string')
});

正如您从注释中看到的，当我将用户数组作为组织的一部分时，我可以看到数据，但是当我保存它时，ember data从未将用户数组作为发送到服务器的数据的一部分发送。

谁能帮我弄清楚发生了什么事?

谢谢。

Stack over flow不会让我在保存emberjs模型时将其标记为Serialize id的副本，但它确实是。Ember Data在这方面是愚蠢的，如果它是一个多对一的关系，它只包括来自belongsTo的id。

App.ApplicationSerializer = DS.RESTSerializer.extend({
 serializeHasMany: function(record, json, relationship) {
    var key = relationship.key;
    var payloadKey = this.keyForRelationship ? this.keyForRelationship(key, "hasMany") : key;
    var relationshipType = RelationshipChange.determineRelationshipType(record.constructor, relationship);
    if (relationshipType === 'manyToNone' || relationshipType === 'manyToMany'
        || relationshipType === 'manyToOne') {  // This is the change
      json[payloadKey] = get(record, key).mapBy('id');
      // TODO support for polymorphic manyToNone and manyToMany relationships
    }
  },
});
