Rails 3 output flushing

How can I "flush" output in Ruby on Rails 3?

In PHP I would do something l开发者_C百科ike the following:

$i = 0;
$total = count($result);
foreach ( $result as $item ) {
    $i++;
    time_consuming_action($item);
    echo "Finished $i of $total<br>";
    flush();
}

I do believe there is a plugin for that.

STDOUT.flush

works for regular Ruby.

template_streaming does not support Rails 3, yet...
