Sigh. It is an existing database (not setup just for Ruby or Rails) with
70,000 records. No auto-increment running on the database because that
been handled by our current main application. If I do anything with
such that Rails implementation of Active Record relies on the database
autoincrement, it is not going to happen because the database does not
that function in this application.
If the Active Record implementation on Rails can calculate the next id,
it won’t create interference. I just don’t understand how Rails
the next unique id if that is not handled by the database.
