but ,it displays error..
"undefined method `name' for #<Book:0x4779224>" any help pls..

Use an association. if you;ve got

class Book
   belongs_to :subject
end

and then

<% @books.each do |c|%>
<%= c.title%>
<%=c.subject.name%>
<% end %>

You don't need the the :joins option (you may want to use :include)
