Answer 1

Have you tried using the sleep method before the erb render?

Answer 2

You can't do what you want in Ruby. You should render your HTML where you could add some javascript or html to redirect after a second or more.

For example add this meta tag

<meta http-equiv="refresh" content="1; url=http://example.com/" />

Where 1 is an amount of seconds
