Something like...
# views/subject/show
<%= link_to 'Would you like to add one?', new_book_path, {:subj => @subject}
%>
# controllers/books_controller
def new
@book = Book.new
@book.subject = params[:subj]
# etc...
end

Subject: [Rails] Set a select box with default value selected
I am relating to the book & subject example mentioned in the tutorial mentioned
here:
http://www.tutorialspoint.com/ruby-on-rails-2.1/rails-examples.htm
There is a file that goes like show_subjects.html.erb and it will list all the
books for that particular subject we've selected.
Suppose if there were no books to show for the subject we can ideally show a
corresponding message like "there are no books for this subject yet"
I'd like to rewrite that is "there are no books for this subject, would you
like to add one?"
Lets say that the 'would you like to add' part is a link to the book create
view where in we add a book. How do I load that page to have its select box
show the subject tht had no books (from where I was initially at)...?
