Question

我是编程Ruby的新手，我需要一些帮助。

我想在检查时显示客户代码和客户名称。但我只得到客户代码而不是客户名称。我如何获得客户名称？

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when关键字。

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

我删除了customernumber == customer[customernumber.to_sym]，因为它已由gets

分配

Ruby Key和值put
