Ruby Ruby Objects and Classes Build a Bank Account Class Adding Transactions

Help needed pushing a hash to an array in a method

The task is: Now that the add_transaction method exists, make the add_transaction method append a hash to the @transactions array. The hash should have the keys description and amount, as symbols, and values that match the arguments to the method.

This is what I've done - and it's not passing. Any suggestions?

class BankAccount attr_reader :name

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

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

end

bank_account.rb
class BankAccount
  attr_reader :name

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

end

Hey Caitlin!

This is a little tricky, but here is what I did:

def add_transaction(description, amount)
  @transactions.push({:description => description, :amount => amount})
end

This function uses the .push function to add the hash {:description => description, :amount => amount} to the already existing @transactions array. Does that make sense?

For some reason they've made it so we have to use symbols for the keys in this challenge (r.e. Jacob Herrington's answer above). Maybe mentioning that in the challenge description would be good?
