I’m having some problems with observe_form and several multiple selects.
My form contains 5 multiple selects and I would like to send the
selected values from each of them to my controller.
Usually you would create a string of the values in the :with parameter,
but it would be quite ugly to make a oneliner looping through select
boxes to find selected indexes.
How does people usually solve this?
I tried making a function that returns a string of parameters, but I
just got bogus calling it from :with.
