Rewriting an ATM program to require two files - ruby

Question

I've created an ATM program and would like to rewrite certain aspects of it to require two files, one containing the names on the accounts and the money information, the other containing the pin number information here's the current code for the working ATM:
class Account
attr_reader :name, :checking_account, :savings_account, :transfer
def initialize(name, checking_account, savings_account)
#name = name
#checking_account = checking_account
#savings_account = savings_account
#transfer = transfer
end
def pin
#pin = '1234'
end
def display
puts "Welcome back #{name} enter your PIN:"
input = gets.chomp
if input == pin
main_menu
else
bad_pin
end
end
def main_menu
puts """
Welcome back #{name}!
Follow the instructions as follows:
To display Balance press '1'
To make a Withdrawl press '2'
To make a Deposit press '3'
To Transfer funds press '4'
To exit the system press '5'
"""
input = gets.chomp
case input
when '1'
balance
when '2'
withdrawl
when '3'
deposit
when '4'
transfer
else
exit
end
end
def balance
puts "Which balance? Checking or Savings?"
input = gets.chomp
if input =~ /checking/i
puts "Your balance for your Checking Account is: $#{checking_account}."
main_menu
elsif input =~ /savings/i
puts "Your balance for your Savings Account is: $#{savings_account}."
main_menu
else
main_menu
end
end
def withdrawl
puts "Please press '1' to make a withdrawl from checking. Press '2' to make a withdrawl from Savings. Press '3' to go back to the menu."
input = gets.chomp
case input
when '1'
puts "How much would you like to withdrawl?"
input = gets.chomp!
#checking_account -= input.to_f
puts "You have withdrawn $#{input}; you now have $#{checking_account} in your checking. Thank you for using this ATM you will be redirected to the main menu."
main_menu
when '2'
puts "How much would you like to withdraw?"
input = gets.chomp!
#savings_account -= input.to_f
puts "You have withdrawn ${input}; you now have $#{savings_account} in your savings. Thank you for using this ATM you will be redirected to the main menu"
main_menu
else
main_menu
end
end
def deposit
puts "Which account would you like to deposit into: Checkings(1), or Savings(2)?"
input = gets.chomp
if input == '1'
puts "Enter amount to deposit: "
amount = gets.chomp!
#checking_account += amount.to_f
puts "You have made a depost of $#{amount} leaving you with $#{checking_account}. Thank you for using this ATM. You will be redirected to the main menu."
main_menu
elsif input == '2'
puts "Enter amount to deposit: "
amount = gets.chomp!
#savings_account += amount.to_f
puts "You have made a deposit of $#{amount} leaving you with $#{savings_account}. Thank you for using this ATM. You will be redirected to the main menu."
main_menu
else
main_menu
end
end
def transfer
puts "Would you like to transfer funds from Checking(1) or Savings(2)?"
input = gets.chomp
if input == '1'
puts "Enter amount to transfer from Checking to Savings: Current balance #{checking_account}."
amount = gets.chomp
#checking_account -= amount.to_f
#savings_account += amount.to_f
puts "You have successfully transfered #{amount} from your Checking account new balance: #{checking_account}. Savings balance: #{savings_account}. You will be redirected to the main menu."
main_menu
elsif input == '2'
puts "Enter amount to transfer from Savings to Checking: Current balance #{savings_account}."
amount = gets.chomp
#savings_account -= amount.to_f
#checking_account += amount.to_f
puts "You have succesfully transfered #{amount} from your Savings account new balance: #{savings_account}. Checking account balance: #{checking_account}. You will be redirected to the main menu."
main_menu
else
puts "Invalid entry"
exit
end
end
def bad_pin
puts "Access Denied: incorrect PIN"
exit
end
end
my_account = Account.new("Thomas", 500_000, 750_000)
my_account.display
What I want to do is use two separate files, names.text and pins.text one holding the account names and the accounts information(names.txt), the other holding the pin numbers of the account(pins.txt).
names.text I.E.:
my_account = Account.new("Thomas", 500_000, 750_000)
my_account.display
my_account2 = Account.new("Jake", 50_000, 50_000)
my_account.display
my_account3 = Account.new("Anothername", 10, 50)
my_account.display
The file with the pin numbers(pins.txt) I think would look something like this(if not please enlighten me):
my_account #pin = 1234
my_account2 #pin = 2345
my_account3 #pin = 3456
So my questions are:
Where would I need to rewrite this code in order to acquire the information from the files, apart from the obvious pin method.
Would I need to use require or require_relative?
