#performed? is an option when getting ActionController::DoubleRenderError

You can avoid `ActionController::DoubleRenderError (Can only render or redirect once per action)` with `#performed?`

For example

def index
  redirect_to not_found_path unless authenticated?
  render :action => 'update' unless performed?
end
