Question

我的客户端API以下列格式返回JSON：

{
    "Result": [
        {
            "member": {
                "id": 1,
                "name": "Mark Smith",
                "email_address": "name@email.com",
                "member_type": [
                    "Premium"
                ],
                "privileges": [
                    "MEMBER"
                ]
            },
            "activites": {
                "ActivityId": "15",
                "ActivityName": "Tennie"
            }
        }
    ],
    "ResultCount": 1 
}

我需要映射到我的Ember app模型：

App.Member = DS.Model.extend({                                                                             
  memberid:             DS.attr('number'),
  membername:          DS.attr('string'),
  memberemail:        DS.attr('string'),
  membertype:          DS.attr('string'),
  memberprivileges:         DS.attr('number'),
  activityID:           DS.attr('number')
});                                                                                                          


App.MemberSerializer = DS.RESTSerializer.extend({                                                                  
extractArray: function(store, type, payload, id, requestType){         
...

我尝试使用Serializer来映射json和app模型之间的字段，但不知道如何使用extractArray这样做，因为我找不到任何有关如何操作的教程/示例，所以有人可以请根据我的客户端JSON结构向我提供了如何执行此操作的示例？

我根据詹姆斯的回复做出的补充：

App.ArrayTransform = DS.Transform.extend({
  deserialize: function (serialized) {
    return (Ember.typeOf(serialized) == "array")
      ? serialized
      : []
  },

  serialize: function (deserialized) {
    var type = Ember.typeOf(deserialized)
    if (type == 'array') {
      return deserialized
    } else if (type == 'string') {
      return deserialized.split(',').map(function (item) {
        return jQuery.trim(item)
      });
    } else {
      return []
    }
  }
})


App.register("transform:array", DS.ArrayTransform);

App.Member = DS.Model.extend({                                                                             
    cont : DS.attr('array')    
});

您需要为数组

制作和使用自己的DS.Model对象

/**
 * Configure a transform for DS.Model Arrays
 * DS.attr('array')
 */
App.ArrayTransform = DS.Transform.extend({
  deserialize: function (serialized) {
    return (Ember.typeOf(serialized) == "array")
      ? serialized
      : []
  },

  serialize: function (deserialized) {
    var type = Ember.typeOf(deserialized)
    if (type == 'array') {
      return deserialized
    } else if (type == 'string') {
      return deserialized.split(',').map(function (item) {
        return jQuery.trim(item)
      });
    } else {
      return []
    }
  }
})

试试这个：

App.Member = DS.Model.extend({                                                                             
    memberid: DS.attr('number'),
    membername: DS.attr('string'),
    memberemail: DS.attr('string'),
    membertype: DS.attr('string'),
    memberprivileges: DS.attr('number'),
    activityID: DS.attr('number')
});                                                                                                          


App.MemberSerializer = DS.RESTSerializer.extend({
    attrs: {
        memberid: 'id',
        membername: 'name',
        memberemail: 'email',
        membertype: 'type',
        memberprivileges: 'privileges',
        activityID: 'ActivityId'
    }
});
