I can't understand why my method isn't correctly formated

Here is the to_s method I wrote

def to_s puts "Name: #{@name}, Balance: #{balance}" end

In my IDE, it returns the right result. Can you please explain me why it isn't accepted ?

David

bank_account.rb
class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
    add_transaction("Beginning Balance", 0)
  end

  def balance
    balance = 0
    @transactions.each do |transaction|
      balance += transaction[:amount]
    end
    balance
  end

  def debit(description, amount)
    add_transaction(description, -amount)
  end

  def credit(description, amount)
    add_transaction(description, amount)
  end

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

  def to_s
    puts "Name: #{@name}, Balance: #{balance}"
  end
end

bank_account = BankAccount.new("David")
bank_account.to_s

Hi David,

I believe that the problem is that you have to remove the puts method and write the to_s method as :

def to_s
    "Name: #{@name}, Balance: #{balance}"
  end

This line:

 puts "Name: #{@name}, Balance: #{balance}"

returns nil from the method and writes the string to the console. That's why you would see the correct string in your IDE but the program would only see nil.

I hope this helps and good luck!
