Hello Guys, I am totally new to rails so sorry if I ask some silly questions, I am also totally confused which is likely self inflicted! So I am learning rails and rjs - I have two models Manufacturers Models So Manufacturers would contain things like Ford, Aston Martin and Models would contain the cars like Ford -> Focus, Escort Ferrari => DB7, DB6, DB5 So I have the simple rails framework working, so firstly a index of ''Manufacturers'' would show all the Manufacturer''s, you could then click a Manufacturer and it would display all the models for that Manufacturer, and then you can click a Model and you can ''edit'' that models. But what I want is to have them all on one page - so what I want is the index page has a select, once you select a manufacturer it grabs all the models and now displays them in a ''select'' - you then chose a model and it then loads the ''edit'' page. Now what I have done so far is in my index.erb <h1>Listing Manufacturer</h1> <% form_remote_for "manufacturer", :html => {:id => ''form1'', :name => ''form1''} do |f| %> <table border="1" width="50%"> <tr> <td width="30%">Please select Manufacturer</td> <td><%= collection_select(:manufacturer, :id, @manufacturer, :id, :manufacturer, {:include_blank => ''''}, {:onchange => "document.form1.onsubmit()"}) %></td> </tr> </table> </div> <div id="show_models"></div> <% end %> And my show.rjs will do something like page.replace_html :show_models, :partial => ''show'', :object => @manufacturer Now I tried to do something similar to the index.erb for each ''model'' e.g. <table border="1" width="50%"> <tr> <td width="30%">Please select Model</td> <td><%= collection_select(:model, :id, @manufacturers.models, :id, :title, {:include_blank => ''''}, {:onchange => "document.form1.onsubmit()"}) %></td> </tr> </table> But of course this submits the form to the same controller/action for the manufacturers not the models controller... Anyone got any advice on how to do this sort of thing? Much Appreciated Paul -- Posted via http://www.ruby-forum.com/.
