Answer 1

A simple approach without ajax could be using a checkbox inside a form and submitting the form with the checkbox javascript onclick event.

Example:

---

View:

<% form_for @rsvp, :id => "rsvp" do |f| %>
  <%= f.check_box :called, :onclick => "$('#rsvp').submit()" %>
<% end %>

this if you are using JQuery... with prototype the onclick string will be:

$('rsvp').submit()

Controller:

@rsvp = Rsvp.find(params[:id])
if @rsvp.update_attributes(params[:rsvp])
  # success
else 
  # fail
end
