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

HTH,

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)...?
