Won't I be able to add the logic I need for debts using has_many belongs_to? Basically all that I would need is to gather which debts I(as the user) have and be able to(in future) toggle their 'paid/unpaid' status. Or would it be better to have a relationship table? via has_many through?
As of the soft deleting I'm gonna narrow it down haha at first I'm just trying to build some concrete functionality, this is just to show some coding skills for an internship, gonna try 'n develop it much further when I get the time and skills. Anywyay, thanks for helping!
