Are you just trying to go to that page? If so then use redirect_to rather than render, this will go to the subjects#index action on subjects and then render it as normal. As you have it you are trying to render the view without calling the action, so @subjects is not set up. If you are trying to do something other than just going to that page then please explain in more detail.
