如何从序列化对象(gem Netflix/fast_jsonapi)中跳过关系散列?

{
  "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"
        }
      }
    }
  }
}

您可以使用rails except method从散列中移除属性,在您的案例中可以使用

 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)

输出如下

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

以及 data_hash 将

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