Hi all, I'm very new to this community, and I started practicing with Ruby on Rails just recently. I watched the 3 episodes , 72-73-74 for complex forms on railscasts , and I'm trying to deploy a "new" function for my form based on what I saw in the 3 episodes. So, I have a form for my master table, with 2 fields: one is named "from_pl" and the other is named "to_pl". What I'd like to achieve is the possibility of adding (to_pl - from_pl) children to the form with the click on a link. So my model is perfectly shaped, and the link Add child , in the vein of the referenced episode of railscasts is perfectly working, the code in the new.html.erb is <%= link_to_function "Add Child" do |page| page.insert_html :bottom, :percentages, :partial => 'percentage', :object => MatchPercentage.new end %> I'd like to add more than 1 child , and I tried with a loop. So far, using <%= link_to_function "Add Child" do |page| 3.upto(6) do page.insert_html :bottom, :percentages, :partial => 'percentage', :object => MatchPercentage.new end end %> works fine. I'd like to substitute the 3 and the 6 with the values of the 2 fields in the form, which has not yet been submitted. I tried with a lot of different searches on the web, but didn't find anything suitable. Could you please enlighten me if there is a solution or not? Thanks a lot, Kind regards
OK guys, think I solved it by spending a little more time. Instead of using Ruby code for looping, I used js enflation with the page << command. This is what did it for me: <%= link_to_function "Add Child" do |page| page << "for(i=$('from_pl').value;i<=$('to_pl').value;i++) {" page.insert_html :bottom, :percentages, :partial => 'percentage', :object => MatchPercentage.new page << "}" end %> Posting it as maybe someone else will need it. Cheers
