如何根据“最佳实践”从第三方抓取的 JSON 请求中获取的数据在模型中创建行

描述问题：

我想从dataforseomodel.create()爬取数据，并通过具有多模型与模型的多关系的方法将它们直接保存在模型数据库中，例如在模型A中

1. 与模型B的多对多关系

2. 与模型C的多对多关系

3. 与模型D的多对多关系

   和模型B与模型C有关系

所以我的问题是如何通过模型A创建方法顺利保存对上述所有模型的JSON响应

响应来自请求：

[
   {
      "title":"title",
      "url":"url",
      "description":"description",
      "pre_snippet":"pre_snippet",
      "extended_snippet":"extended_snippet",
      "images":"images",
      "amp_version":"amp_version",
      "rating":{
         "rating_type":"rating_type",
         "value":"value",
         "votes_count":"votes_count",
         "rating_max":"rating_max"
      },
      "price":{
         "current":"current",
         "regular":"regular",
         "max_value":"max_value"
      },
      "highlighted":{
         "name_highlighted":"name_highlighted"
      }
   },
   {
      "title":"title",
      "url":"url",
      "description":"description",
      "pre_snippet":"pre_snippet",
      "extended_snippet":"extended_snippet",
      "images":"images",
      "amp_version":"amp_version",
      "rating":{
         "rating_type":"rating_type",
         "value":"value",
         "votes_count":"votes_count",
         "rating_max":"rating_max"
      },
      "price":{
         "current":"current",
         "regular":"regular",
         "max_value":"max_value"
      },
      "highlighted":{
         "name_highlighted":"name_highlighted"
      }
   }
]
