this can be done without having to pass the current toggle status
the view
<% orders.each do |order| %>
<tr>
<td><%= order.whatever%></td>
<td id="#{order.id}"><%= link_to_remote image_tag("path_to_image"),
url_to_toggle_method(:id => order.id) %></td>
</tr>
<% end %>
the controller
def toggle
@order = Order.find(params[:id])
@order.toggle_the_boolean_attribute_based_on_its_current_value
@order.save(false)
render :update do |page|
page.replace_html "#...@order.id}",
the_new_image_with_link_to_remote
end
end
there are a few things missing and its untested but thats definitely
one way to go. look into render :update.
