After reading a bunch of Ruby tutorials, I decide to write fake ATM bank software. I've tried to use OOP design and just want to know if I'm on the right road.
require "yaml"
require 'colorize'
class Person
attr_accessor :info
def initialize(info={})
@info = info
end
def change_info(info={})
self.info = info
end
def full_name
full_name =info[:first_name]
if !@middle_name.nil?
full_name += " "
full_name += info[:middle_name]
end
full_name += ' '
full_name += info[:last_name]
full_name
end
end
module Transaction
#contains all the operation need to manage a bank
def balance
# return balance for each new object
puts"-----------------------------------"
puts" Accounts balance - #{@account_number}"
puts"-----------------------------------"
puts "Your actual balance is $#{info[:balance]}"
puts"-----------------------------------"
end
def deposit(amount)
#add amount to the balance and return the aggregated amount
depo_trans = @info[:balance] += amount
@deposit.push(depo_trans)
end
def withdrawal(amount)
depo_withdrawal = @info[:balance] -= amount
@withdrawal.push(amount)
end
def transac_info
count = 0
transac_counter = count += 1
puts"--------------------------------"
puts" Transaction Lists-#{@info[:first_name]} "
puts"---------------------------------"

puts"-----------Deposit---------------"
[email protected]{|trans| puts "$#{trans}"}
puts"Total deposit"

puts"$#{total}"

[email protected]{|withd| puts "$#{withd}"}
diff =less.sum
puts "Total withdrawal"
puts"$#{diff}"
puts"-----------Bank Balance----------"
bank_bal = total + diff
puts "$#{bank_bal}"
end
def transfer( account_number,pin, amount)
origin = @info[:balance]
lists=BankAccount.account_list
lists.each do |list|
if account_number == list[:account_number] && list[:pin] == pin

exit
