Ruby密鑰和價值投入

Question

嗨即時編程Ruby的新手，我需要一點幫助。

我想在顯示客戶代碼和客戶名時進行檢查。但我只獲取客戶代碼而不是客戶名稱。我如何獲得客戶名？

customer = { 
C00001: "Tyler Dinges", 
C00002: "Jannie de Vries", 
C00003: "Klaas Bruinsma", 
} 

when 'searchcustomer' 
puts "Witch customer are you looking for?" 
customernumber = gets.chomp 
if customer[customernumber.to_sym].nil? 
    puts "customer is not found" 
else 
    customernumber == customer[customernumber.to_sym] 
    customer[customernumber.to_sym] 
    puts "#{customernumber} #{customername} Is a customer!" 
end 

感謝您的幫助！

您需要刪除關鍵字when。

customer = { 
    C00001: "Tyler Dinges", 
    C00002: "Jannie de Vries", 
    C00003: "Klaas Bruinsma", 
} 


puts "Witch customer are you looking for?" 
customernumber = gets.chomp 
if customer[customernumber.to_sym].nil? 
    puts "customer is not found" 
else 
    customername = customer[customernumber.to_sym] 
    puts "#{customernumber} #{customername} Is a customer!" 
end 

我刪除customernumber == customer[customernumber.to_sym]，因爲它已經被gets
