Ruby on rails 如何在Jbuilder中合并JSON对象

我正在创建一个rails应用程序，具有主干/木偶前端。 我想获取下面的JSON对象并对其进行转换

这就是它现在的样子

[{
        "total_entries": 4
    },
    {
        "entries": [{
                "user": {
                    "id": 1,
                    "fullname": "Paul Paulsen"
                },
                "reports": [{
                        "id": 1,
                        "name": "Anna Pearson",
                        "relation": "wife",
                        "phone": "2232",
                        "email": "adsas@sss.se"
                    }
                ]
            },
            {
                "user": {
                    "id": 2,
                    "fullname": "Anna Palmgren"
                },
                "reports": [{
                    "id": 3,
                    "name": "Mika",
                    "relation": "Andersen",
                    "phone": "12312321",
                    "email": "aas@sss.se"
                }]
            }
        ]
    }
]

我想让它看起来像这样

[{
        "total_entries": 4
    },
    {
        "entries": [{
                "id": 1,
                "fullname": "Paul Paulsen"
            }, {
                "id": 1,
                "name": "Anna Pearson",
                "relation": "wife",
                "phone": "2232",
                "email": "adsas@sss.se"
            }, {
                "id": 1,
                "fullname": "Anna Palmgren"
            }, {
                "id": 3,
                "name": "Mika",
                "relation": "Andersen",
                "phone": "12312321",
                "email": "aas@sss.se"
            }

        ]
    }
]

这是我使用的Rabl文件/代码

json.array! [0,1] do |index|
  if index == 0
    json.total_entries @total
  else
    json.entries @reports.group_by(&:user) do |user, reports|
      json.user user, :id, :fullname
      json.reports reports do |report|
        json.extract! report, :id, :name, :relation, :phone, :email
      end
    end
  end
end

试试这个ruby代码片段

    x= [{
            "total_entries": 4
        },
        {
            "entries": [{
                    "user": {
                        "id": 1,
                        "fullname": "Paul Paulsen"
                    },
                    "reports": [{
                            "id": 1,
                            "name": "Anna Pearson",
                            "relation": "wife",
                            "phone": "2232",
                            "email": "adsas@sss.se"
                        }
                    ]
                },
                {
                    "user": {
                        "id": 2,
                        "fullname": "Anna Palmgren"
                    },
                    "reports": [{
                        "id": 3,
                        "name": "Mika",
                        "relation": "Andersen",
                        "phone": "12312321",
                        "email": "aas@sss.se"
                    }]
                }
            ]
        }
    ]

   x[1][:entries] = x[1][:entries].map{|p| [p[:user], p[:reports]]}.flatten

这不是语法。你在展示，他们是不同的。对不起，你是对的。我现在已经编辑了。您需要尝试

ActiveRecord:：Base.include\u root\u in\u json=false

以省略根对象ffom响应。别忘了重新启动服务器。
