Ruby Objects and Classes Transactions, Credits and Debits

I'm following along with the video in Sublime and Ruby, and when I run the program I get this error message:

ruby bank_account.rb bank_account.rb:11:in add_transaction': undefined methodpush' for nil:NilClass (NoMethodError) from bank_account.rb:25:in `<main>'

Here's my code:

class BankAccount
    attr_reader :name

    def initialize(name)
        @name = name
        @transations = []
    end

    def add_transaction(description, amount)
        @transactions.push(description: description, amount: amount)
    end
end

bank_account = BankAccount.new("Joy")
bank_account.add_transaction("Groceries", 40)

Why in the world is it not recognizing the push method?

I think it may be, because you have (def add_transaction) and underneath that, you have @transactions.push .Further down, you have bank_account.add_transaction, on the very bottom line.

So, I think that you have to maintain consistency as far as whether or not you want to have (transaction, or transactions) ; and than stick with the same form.

As far as I can tell, you did the actual coding correctly, but there are some small typos.

def initialize(name) @name = name @transations = []

I think the typo above is causing your issue, this should be @transactions rather than @transations

no problem, I have had countless issues caused by a small typo already, part of the learning curve!

happy coding!
