Is cookies[:my_key] just a single value? If so then do as I suggested
in my previous post
@my_key = cookies[:my_key]
and then it will be available in @my_key in the view.

I don't know what you are using the cookie for of course, but have you
considered using the session variable instead? That might be simpler
if it does what you need.
