Hi:

Don’t know if this the right title for what I’m looking for, but  
basically I want to be able to figure out what controller and actions  
are being fired.

Let me describe specifically what I’m looking for:

I have a partial that’s implemented on two pages. This partial has  
actions in it. If the user executes an action in this partial, I want  
the action to complete and then for them to be redirected to the page  
the partial’s in, which would basically be a reload. I found  
“params[:controller]” & “params[:action]” but I really want not the  
current controller and action but the previous one, or even better, the  
page that the partial’s in. How do I do this?

Thanks so much in advance!

Mike
