Question : What is the command for rails to reload the current page after executing code?

I would like the rails app to reload the page that it came from after executing a method.  

I can get it to reload a specific page (redirect_to :action => 'list'), however I want it to reload the page that just executed the method.  So, I tried this:  

redirect_to :action => 'show', :id => @video

with @video being a variable that is being used on the page already, however it says "can't find video without an ID".  So apparently the variable is not being passed to the method.  

I would like to know how to have a method redirect to/render the page that called it anyway, for other uses.

Thanks in advance,
Darin

Here is the method:

redirect_to :back

From the API:

* :back - Back to the page that issued the request. Useful for forms that are triggered from multiple places. Short-hand for redirect_to(request.env["HTTP_REFERER"])

So, you could use the environment variable of the referer, but :back is a shortcut.
