If I read things correctly what you are effectively wanting to do something specific when a standard rails form is submitted in the standard way.

Notice that when a form is submitted using e.g.

f.submit "Save Changes"

then

params[:commit] = "Save Changes"

The GOOD thing about this is that it can allow you to do some appropriate branching in the controllers update action.

The BAD thing is that it's brittle. If one day you or someone else decides to change the button text, things break.. which is bad.
