Pulling values from forms text fields to other locations in ruby on rails html

Question

I am new to ruby on rails and am composing a library for books. Most of it is working except for moving a scanned in isbn from a text field on a page to another text field.

<%= form_for @book, :html => { :class => 'form-horizontal' } do |f| %>
  <div class="control-group">
    <%= f.label :isbn, :class => 'control-label' %>
    <div class="controls">
      <%= f.text_field :isbn, :class => 'text_field' %>
      <%= link_to t('.new_autofill', :default => t("helpers.links.Auto Fill")),
            autofill_books_path( :isbnvalue => :isbn ),
            :class => 'btn btn-primary' %>
    </div>
  </div>
  <div class="control-group">

The code above takes the value isbn and passes it into the controller that sets up the page autofill. I need the isbn text_field value, not its label value which is what I think I am obtaining. How do i grab this value? Thank you for any help.

You can use Javascript to do that as outlined in this SO post.

If you want to do it with rails, you can create a new action in the book controller and link to it in the form instead of autofill_books_path, for instance get_isbn:

def get_isbn
  @isbn = params[:book][:isbn]

  redirect_to autofill_books_path(isbnvalue: @isbn)
end

Of course you should include validation to check if the isbn provided is correct.
