I’ve got a 4 step checkout. During the 2nd step, I collect order info
set to a model variable Order and store that in a session var called
session[:order] to process later or repopulate the form if they do not
finish checkout. I do NOT, however want to store the credit card number
the session, yet I still need to carry it over from the 2nd step to the
What’s the best way to carry the CC# over a few steps without storing it
the session and without creating a hidden form input. Class variables?
