OK - i have this form, and i works perfect :) <%= form_remote_tag(:update => "status", :url => "/image/worksafe/" + image.id.to_s) %> <%= check_box_tag :worksafe, value = "1", checked = image.worksafe%> <%= submit_tag "Change status", :name => image.sha %> <%= end_form_tag %> however - the submit button is kind of annoying, since you often have to check/uncheck a lot of things at once. So - i made this "standalone" checkbox <%= check_box_tag :worksafe, value = "1", checked = image.worksafe, :onchange => remote_function( :update => "status", :url => "/image/worksafe/" + image.id.to_s )%> but the problem is - when you check/uncheck it the value "1" is never send. This basically means that you can use the button to turn things off, but not on :) I''ll hope you can help. thanks -- Posted via http://www.ruby-forum.com/.
