This seems to work. but feels like a hack... Thoughts anyone?
Updated the application.js to run:
$.ajax({
url: '/books',
});
Created a _index.html.erb that has the books view (just copied it from
index.html.erb so I had a partial.
Then in the index.js.erb, added this:
$(".contentCol").html("<%=escape_javascript(render :partial =>"books/
index")%>");
My books controller is the same as the last post...
Thoughts? is this perfect? Crap? Hacky? etc? thxs!!!
