Setting value as params on creation - ruby-on-rails

Question

Attempting to make different orders where depending on the order there is different revisions_left which is an integer in the migration file.
I pass the params[:orderref] through a button like so <%= link_to 'Package 1', new_order_path(orderref: 1)%> and then am trying to call it in the create method like so
if params[:orderref] == "1"
#order.revisions_left = 1
elsif params[:orderref] == "2"
#order.revisions_left = 2
elsif params[:orderref] == "3"
#order.revisions_left = 3
end
However the revisions_left fails to save and am unsure why
