Return another object in an object's method

Is there a way to do this in ruby?

a = UnauthenticatedClient.new
a.class #=> #<UnauthenticatedClient>

a.login!("username", "password")
a.class #=> #<AuthenticatedClient>

No, but you can do this:

a = UnauthenticatedClient.new
a.class #=> #<Unauthenticated>

a = a.login!("username", "password")
a.class #=> #<Authenticated>

A method may return a different object, but it cannot change the reference to that object:

class UnauthenticatedClient
  def login!(username, password)
    # do the login process...
    Authenticated.new(authentication_params) # returns a new object of type Authenticated
  end
end

You can also consider using attributes instead of classes to determine whether the client is authenticated or not:

a = Client.new
a.class #=> #<Client>
a.authenticated? # false

a.login!("username", "password")
a.class #=> #<Client>
a.authenticated? # true
