ruby - 如何在 Grape 中定义哈希数组？

Question

我使用 Ember 作为我的前端和 Grape API 来为我的 API 提供服务。

前端发送类似:

{
  "service"=>{
    "name"=>"Name",
    "duration"=>"30",
    "user"=>nil,
    "organization"=>"org",
    "category"=>nil,
    "description"=>"description",
    "disabled"=>true,
    "color"=>nil,
    "availabilities"=>[
      {
        "day"=>"Saturday",
        "enabled"=>false,
        "timeSlots"=>[
          {
            "startAt"=>"09:00 AM",
            "endAt"=>"05:00 PM"
          }
        ]
      },
      {
        "day"=>"Sunday",
        "enabled"=>false,
        "timeSlots"=>[
          {
            "startAt"=>"09:00 AM",
            "endAt"=>"05:00 PM"
          }
        ]
      },
      {
        "day"=>"Monday",
        "enabled"=>true,
        "timeSlots"=>[
          {
            "startAt"=>"09:00 AM",
            "endAt"=>"05:00 PM"
          },
          {
            "startAt"=>"05:00 AM",
            "endAt"=>"09:00 PM"
          },
          {
            "startAt"=>"05:00 AM",
            "endAt"=>"09:00 PM"
          }
        ]
      },
      {
        "day"=>"Tuesday",
        "enabled"=>true,
        "timeSlots"=>[
          {
            "startAt"=>"09:00 AM",
            "endAt"=>"05:00 PM"
          }
        ]
      },
      {
        "day"=>"Wednesday",
        "enabled"=>true,
        "timeSlots"=>[
          {
            "startAt"=>"09:00 AM",
            "endAt"=>"05:00 PM"
          }
        ]
      },
      {
        "day"=>"Thursday",
        "enabled"=>true,
        "timeSlots"=>[
          {
            "startAt"=>"09:00 AM",
            "endAt"=>"05:00 PM"
          }
        ]
      },
      {
        "day"=>"Friday",
        "enabled"=>true,
        "timeSlots"=>[
          {
            "startAt"=>"09:00 AM",
            "endAt"=>"05:00 PM"
          }
        ]
      }
    ]
  }
}

我正在努力实现 Grape api 接口(interface)来接收有效载荷，我最终得到了类似的东西:

  resource :services do
    params do
      requires :service, type: Hash do
        requires :name, type: String
        requires :organization, type: String
        requires :duration, type: Integer
        requires :category, type: String
        optional :color, type: String
        optional :description, type: String
        optional :disabled, type: Boolean
        requires :availabilities, type: Array do
          requires :day, type: String
          optional :enabled, type: Boolean
          optional :timeSlots, type: Array do
            requires :startAt, type: Time
            requires :endtAt, type: Time
          end
        end
      end
    end
    post do
      puts params
    end
  end

但运气不好，因为我收到以下错误:

ERROR -- service[availabilities][0][timeSlots][0][endtAt] is missing

您可以尝试使用“组”来指示您的数组元素的类型。

示例(更新):

params do
  group :services, type: Array, desc: "An array of services" do
    requires :name, type: String
    requires :organization, type: String
    requires :duration, type: Integer
    ...
  end
end
put '/test' do
  s = []
  params[:services].each do |service|
    s << service
  end
  return s
end
