A simple Rails banking app. Users can be created in console. You can create Users through console and add credit to their account.
User.create login: 'satoshi',password: 'nakomoto',:password_confirmation: 'nakomoto'
User.find_by_login('satoshi').account.add_credit 100
Users are able to sign in with their login and password. After login the User can make payments to other Users until they get an Account::BalanceExceededException because they tried to pay an amount which they don't have. It is also impossible to try and pay a negative amount in order to credit their account, a Transfer::NegativeAmountException is raised.
On the account page there is an audit trail so we can see how we got to the current balance.
