Please have a look at this very simple Rails scaffold app with a modal:
https://github.com/walterdavis/modal-test
git clone it, rake db:migrate, rails s, and look at it in a browser. Add some
posts, then return to the index page and click on the Show link and then the
Modal link (they are different). See how the modal appears and shows you any
post you click on when you use the modal link.
