Topic: Primary keys
I am extremely confused about how rails handles primary keys when the migration tool is not used. What if we just create a primary key column called "id" using sql? Rails doesnt seem to auto-increment the id even though the column is called "id". If I understand correctly, rails automatically increment primary keys if the column is called "id", if not, we have to specifically tell rails what the primary key column is. Any direction will be greatly appreciated.
