The render line does not invoke the static_pages controller, it just
invokes the view files for static_pages/home, so it will not call the
static_pages controller to setup your variables. I don't know how your
debug got to that code, I suspect it was from a different part of the
test.  Perhaps you meant redirect_to which will invoke the controller
to perform the action.  You may find this useful -
