Ugly way of opening a Django shell via a Vagrant command... there must be a better way?

Vagrantfile

Vagrant::Config.run do |config|

        config.vm.box = "lucid64"
        config.vm.box_url = "http://files.vagrantup.com/lucid64.box"

        config.vm.host_name = "myvagrantbox"
        
        # etc.
end


class DjangoShellCommand < Vagrant::Command::Base
  def execute
    # Open the interactive Django shell on the Vagrant box
    exec 'ssh -t myvagrantbox "python manage.py shell"'
  end
end
Vagrant.commands.register(:shell) { DjangoShellCommand }
