#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
