作成しようとしているRubyメソッドに問題があります

Question

次のコードを実行しようとしていますが、私が必要とする応答が得られません。私は、クライアントの詳細ハッシュで子どもへの答えを設定したい。私はかなり私の子供のメソッドでget.chompがあるので、私はかなり確信していますが、私は私のハッシュにそれをシャベルすることができます私は整数にその応答を設定することはできません。ここで

# Get following details from client: 
# name 
# age 
# number of children 
# decor theme 
# handicap 
# if handicap ask if they would like wheelchair ramp or elevator. 
# Program should also: 
# Print the hash back to screen when designer answers all questions 
# Give the user the option to update a key. Exit if user says "n." If  user enters "key," program should ask for new key value and update key. (Strings have methods to turn them into symbols.) 
# Print latest version of hash, exit 


def children(response) 
until response == "y" || response == "n" 
     puts "Invalid response, Please enter Y/N only!" 
     response = gets.chomp.downcase 
    end 
     if response == "y" 
     puts "How many children do you have?" 
     number_of_children = gets.chomp.to_i 
     else response == "n" 
     number_of_children = 0 
     end 
end 




client_details = {} 

# ---- Driver Code ---- 

puts "Welcome to the Client Information Form!" 

# ---- get the user name ---- 
puts "Please enter the Clients Full Name:" 
client_details[:name] = gets.chomp 
# ---- get the user age ---- 
puts "Please enter #{client_details[:name]} age:" 
client_details[:age] = gets.chomp.to_i 
# ---- find out if the user has children ---- 
puts "Does #{client_details[:name]} have any children? (Please enter Y/N only)" 
children_input = gets.chomp.downcase.to_s 
children(children_input) 



client_details[:children] = children(children_input) 
p client_details 

は、私は、コードを実行したときに何が起こるかです：

'Welcome to the Client Information Form! 
Please enter the Clients Full Name: 
Art V 
Please enter Art V age: 
55 
Does Art V have any children? (Please enter Y/N only) 
y 
How many children do you have? 
8 
How many children do you have? 
8 
{:name=>"Art V", :age=>55, :children=>8} 

Answer 1

あなたが重複した出力を得る理由は、あなたが二回childrenメソッドを呼び出しているということです。

# this is the first time here 
children_input = gets.chomp.downcase.to_s 
children(children_input) 

# and this is the second time here 
client_details[:children] = children(children_input) 

あなたの場合一度だけ呼びたい場合は、戻り値を保存/保存する必要があります。例：

children_input = gets.chomp.downcase.to_s 
num_children = children(children_input) 
client_details[:children] = num_children
