NoMethodError: undefined method 'each' for #<BankAccount:0x007ff7db82fd40>

Question

I have tried debugging for an hour to no avail.

class BankAccount
    def self.create_for(firstname, lastname)
        @accounts ||= []
        @accounts = BankAccount.new(firstname, lastname)
    end

    def self.find_for(first_name, last_name)
        @accounts.find{|account| account.full_name == "#{first_name} #{last_name}"}
    end

    def initialize(firstname, lastname)
        @balance = 0
        @firstname = firstname
        @lastname = lastname
    end

    def full_name
        "#{@firstname} #{@lastname}"
    end

    def deposit(amount)
        @balance += amount
    end

    def withdraw(amount)
        @balance -= amount
    end
end

And this is my error:

irb(main):045:0> bankaccount = BankAccount.find_for("J","R")
NoMethodError: undefined method `each' for #<BankAccount:0x007ff7db82fd40>

Please rewatch the video, especially 2:28 and make sure your code is correct, especially the self.create_for method with << operator.
