Hi.

In controller code I’m doing things like:

flash[:success] = “Customer {#@customer.name} has been deleted.”

I know how to escape html in views by using the h() method. How can I  
do  
the same thing here in the controller?

Thanks,  
Zack

I don’t think you would do it there – instead, add  
“h(flash[:success])” to your view. (Keep the presentation separate.)
