如何从序列化对象中跳过关系哈希

Question

如何跳过序列化对象（gem Netflix / fast_jsonapi）中的关系哈希？

{
  "data": {
    "id": "3",
    "type": "movie",
    "attributes": {
      "name": "test movie",
      "year": null
    },
    "relationships": {
      "actors": {
        "data": [
          {
            "id": "1",
            "type": "actor"
          },
          {
            "id": "2",
            "type": "actor"
          }
        ]
      },
      "owner": {
        "data": {
          "id": "3",
          "type": "user"
        }
      }
    }
  }
}

在可以使用的情况下，可以使用rails除了方法从哈希中删除属性

 data_hash = {"data": {"id": "3","type": "movie","attributes": {"name": "test movie","year":''},"relationships": {"actors": {"data": [{"id": "1","type": "actor"},{"id": "2","type": "actor"}]},"owner": {"data": {"id": "3","type": "user"}}}}}
 data_hash[:data].except!(:relationships)

您将得到如下输出

{:id=>"3", :type=>"movie", :attributes=>{:name=>"test movie", :year=>""}}

data_hash将

{:data=>{:id=>"3", :type=>"movie", :attributes=>{:name=>"test movie", :year=>""}}}
