[usmanasif]

Hi, I am using include_association to just include those associations. But other associations with that model also getting include. when creating duplicate = object.amoeba_dup its also dup all other association.
My code :

Here i just include these [:mastermind_modules, :kanban_boards,:sessions, :team, :mastermind_categories, :mastermind_experts] but seller_coupons (associated model) also getting associated.
