I am trying to implement some ajax forms and I need to have multiple
buttons that submit the whole form.
I initially tried having two submit buttons and I was planning to read
the value of the button in the controller to see which one was
clicked, and then call the appropriate action. There seems to be a
well known issue with Ajax forms that only the first button gets
serialized so you'll always see the same action. There is a workaround
but it's a little ugly..
I found submit_to_remote which I could use to submit the form data to
different actions, but the book I have says that this function is
unpredictable and shouldn't be used. I can't find any other place
that mentions this.
Is this still true? Is it unreliable to use submit_to_remote? Is
there a better way?
