How to create an object when a check_box is checked?

Is there any way to get a check_box to function in the same way as button_to, for example, so that when the box is checked an object is created?

The code for my button_to is as follows:

<%= button_to("Yes", :action => "create", :controller => "objects", :object => {:boolean => 'true', :object_1.id => current.id}) %>

I want this same event to occur, but when a check_box is checked rather than when a button is clicked. It would be cool if the object could be destroyed when the box is unchecked as well. Is this possible?

In short, no unless you expand your interest into Javascript and AJAX. The long answer is that a checkbox returns no value at all if it is not checked, not a nil value, nothing. The returned parameter looks like this {} ie empty. Whereas you are much safer reacting to a value like {destroy: "yes"} which you can implement with a button.

If you are dead set on a check-box, maybe look at ways of using two checkbox images as your button (one for set, one for not set). Javascript is your friend here, but it is more work and I wouldn't personally do it.
