Ruby密钥和价值投入

Question

嗨即时编程Ruby的新手，我需要一点帮助。

我想在显示客户代码和客户名时进行检查。但我只获取客户代码而不是客户名称。我如何获得客户名？

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 

感谢您的帮助！

您需要删除关键字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 

我删除customernumber == customer[customernumber.to_sym]，因为它已经被gets
