4,587 PointsGetting an error for the print_register method
I'm following along with the video, but I'm getting an error when I try to run the code for the print_register method.
The error I'm getting:
bank_account.rb:38:in print_register': undefined method
each' for nil:NilClass (NoMethodError)
What exactly is the problem with my loop ? I'm at a total loss, I've been re-watching over and over to see where I could have made a mistake but as far as I can tell, it's the same code as in the video O.o ...
My code:
class BankAccount
attr_reader :name
def initialize(name)
@name = name
@transactions = []
add_transaction("Beginning Balance", 0)
end
def credit(description, amount)
add_transaction(description, amount)
end
def debit(description, amount)
add_transaction(description, -amount)
end
def add_transaction(description, amount)
#push a hash into the array w/2 keys : description & amount)
@transactions.push(description: description, amount: amount)
end
def balance
balance = 0
@transactions.each do |transaction|
balance += transaction[:amount]
end
return balance
end
def to_s
"Name: #{name}, Balance: #{sprintf("%0.2f", balance)}"
end
def print_register
puts "#{name}'s Bank Account"
puts "Description\tAmount"
@transaction.each do |transaction|
puts transaction[:description] + "\t" + sprintf("%0.2f", transaction[:amount])
end
puts "Balance: #{sprintf("0.2f", balance)}"
end
end
bank_account = BankAccount.new("Jason")
bank_account.credit("Paycheck", 100)
bank_account.debit("Groceries", 40)
puts bank_account
puts "Register:"
bank_account.print_register

27,258 PointsIn def print_register, I think you need an "s" after transaction. Your variable is @transactions, with an "s"...
