遍历嵌套哈希/数组

Question

我从api调用获得以下响应代码。我正在尝试将以下数据提取到我的数据库中：

Duration ("5 Hours and 21 Minutes"),
Departure ("From LAX at 2020/10/05 - 16:00),
Arrival ("Arriving in JFK at 2020/10/06 - 21:00"),
Price ("256.46"),
Stops ("0")
Currency ("Euro")
Cabin ("Economy")

我的以下代码获得了一些属性，但就我所知，我发现它变得很难编码和丑陋，并且想知道如何使它变得更好：

  res.data.select do |t|
    puts "Flight's total price:#{t["price"]["currency"]}#{t["price"]["total"]}"  
    t["itineraries"].select do |new_t|  
      puts "Flight's duration is: #{new_t["duration"]}"    
      new_t["segments"].select do |another_t|
        puts "Departue at: #{another_t["departure"]["at"]} from #{another_t["departure"]["iataCode"]}"
        puts "Arriving at: #{another_t["arrival"]["at"]} from #{another_t["arrival"]["iataCode"]}"
      end  
    end  
  end 

以下是变量中保存的api的响应代码
