Ruby on rails 如何在JSON API输出中包含模型

您好，我正在创建一个API。我有一个

用户

和

个人资料

模型。用户有一个配置文件

当我得到一个用户端点时，我希望在端点中包含配置文件信息（属性）

到目前为止，我的终点是这样的

 {
    "data" => {
      "id" => user.id.to_s,
      "type" => "users",
      "attributes" => {
        "email" => user.email
      },
      "relationships" => {
        "profile" => {
          "data" => {
            "id" => user.profile.id.to_s,
            "type" => "profiles"
          }
        }
      }
    }
  }

  {
    "data" => {
      "id" => User.last.id.to_s,
      "type" => "users",
      "attributes" => {
        "email" => new_email
      },
      "relationships" => {
        "profile" => {
          "data" => {
            "id" => User.last.profile.id.to_s,
            "type" => "profiles"
          }
        }
      }
    }],
    "included": [
      {
        "type": "profiles",
        "id": "42",
        "attributes": {
          "first_name": "John",
          "last_name": "Smith"
        }
      }
    ]
  }

应该是这样的

 {
    "data" => {
      "id" => user.id.to_s,
      "type" => "users",
      "attributes" => {
        "email" => user.email
      },
      "relationships" => {
        "profile" => {
          "data" => {
            "id" => user.profile.id.to_s,
            "type" => "profiles"
          }
        }
      }
    }
  }

  {
    "data" => {
      "id" => User.last.id.to_s,
      "type" => "users",
      "attributes" => {
        "email" => new_email
      },
      "relationships" => {
        "profile" => {
          "data" => {
            "id" => User.last.profile.id.to_s,
            "type" => "profiles"
          }
        }
      }
    }],
    "included": [
      {
        "type": "profiles",
        "id": "42",
        "attributes": {
          "first_name": "John",
          "last_name": "Smith"
        }
      }
    ]
  }

这是我的用户序列化程序

class UserSerializer < ActiveModel::Serializer
  attributes :email
  has_one :profile
end

class UserSerializer

这是我在用户控制器中的显示操作

module V1
  class UsersController < ApiController
    before_action :set_user, only: [:show, :update, :destroy]

    def show
      render json: @user, include: params[:include], status: :ok
    end


    private

    def set_user
      @user = User.find(params[:id])
    end

    def user_params
      attribute_params.permit(:email, :password, roles: [])
    end

    def assign_roles
    end
  end
end

模块V1
类UsersController

它的设置方式非常完美。我所要做的就是在uri中传递它

像这样

 {
    "data" => {
      "id" => user.id.to_s,
      "type" => "users",
      "attributes" => {
        "email" => user.email
      },
      "relationships" => {
        "profile" => {
          "data" => {
            "id" => user.profile.id.to_s,
            "type" => "profiles"
          }
        }
      }
    }
  }

  {
    "data" => {
      "id" => User.last.id.to_s,
      "type" => "users",
      "attributes" => {
        "email" => new_email
      },
      "relationships" => {
        "profile" => {
          "data" => {
            "id" => User.last.profile.id.to_s,
            "type" => "profiles"
          }
        }
      }
    }],
    "included": [
      {
        "type": "profiles",
        "id": "42",
        "attributes": {
          "first_name": "John",
          "last_name": "Smith"
        }
      }
    ]
  }

get”/v1/用户？页面[number]=1和页面[size]=3&include=profile

在我的表演中

params[：include]

=“profile”
