redirect destination to the same page

I can't find it even if I look into it, so I have a question.
As for how to use redirect_to, I can specify this page, but is it possible to transition to the same page or update the page?

What I want to do is update the page when certain actions occur on the controller.

I don't want you to move pages if possible because there are actions that span multiple pages and it takes a lot of time to move pages every time. Is there such a way?
