  ratyrate_rateable "price_for_sale"
end

books/index.html.erb.

<div class="row">
  <div class="col-md-8">
      <table class="cls_book_details" cellspacing="0" cellspacing="0">  
        <tr>
            <%@count =1 %>
            <% @books.each do |book| %>
                <td id="book_details" style="text align:left;"><%=link_to(image_tag(book.book_photos.first.photo.url(:thumb), :title => 'Click for edit'), edit_book_path(book.id))%><br>

                    Author : <%= book.book_auther %><br>
                    <%= rating_for book, "price_for_sale", :enable_half => true %><br/><br>

                <%@count += 1 %>
                <%if @count == 4%>
                    <% @count =1 %>
                    </tr>
                    <tr>

For that you should check your logged in user with your book user. If they are same then prevent him by doing so

if obj.user.id == current_user.id
  flash[:alert] = "You can not rate your own book"
else
  obj.rate params[:score].to_f, current_user, params[:dimension]
end

Your second question's answer is use ajax not to reload page.

Full detail over AJAX in rails http://edgeguides.rubyonrails.org/working_with_javascript_in_rails.html

Here is an good example http://code.tutsplus.com/tutorials/using-unobtrusive-javascript-and-ajax-with-rails-3--net-15243
