Question

有没有办法导入没有primaryKey或relatedByAttribute的魔法记录数据？

我的JSON看起来像这样。如您所见，这是员工也可以访问的服务列表。我也没有唯一的身份证明。

{
   "status":0,
   "statusMessage":"Call success",
   "details":{
      "items":[
         {
            "status":0,
            "statusMessage":"Employee service schedule list returned",
            "details":{
               "itemsReturned":2,
               "items":[
                  {

使用没有唯一ID的魔法记录导入这些内容的最佳方法是什么？

Answer 1

MagicalRecord导入仍然可以使用此数据。由于您通过json密钥获得了相关对象，因此我们可以知道您希望将核心数据实体与之相关联。此外，只要您正确地将json属性映射到核心数据属性，这也为导入库提供了足够的信息，以确定与导入内容相关的内容。
