幫助我這個代碼T_T爲什麼它繼續顯示語法錯誤，意外「：」 exepcting結束輸入數據庫：{語法錯誤，意外「：」希望結束輸入

database: { 
    total_car_price: 20000, 
    stock_car_price: 20000,

    while true 
     selection = gets.chomp 
     if data.keys.include? selection #make it general that can accept string/integer 
      database[:total_car_price] += data[selection]

請正確格式化您的代碼。 –

嘗試'ruby -w '以獲得有關錯誤發生位置的提示。 –

你試過我的答案嗎？ – araratan

你應該分析你JSON是這樣的：

json = { 
    database: { 
    total_car_price: 20000, 
    stock_car_price: 20000, 
    features: { 
     rim: { 
      '16' => 50, 
      '15' => 30, 
      '14' => 10 
     }, 
     color: { 
      'blue' => 0, 
      'red' => 0, 
      'yellow' => 0 
     }, 
     tint: { 
      '100' => 80, 
      '80' => 50, 
      '50' => 0 
     }, 
     seat: { 
      'leather' => 500, 
      'PVC' => 300 
     } 
    } 
} 
} 

parsed_json = JSON.parse(json.to_json) 

puts "Original price : #{parsed_json['database']['stock_car_price']}"

這裏是工作樣例：
