Just another quick solution. You can generate the Ruby
scaffolding commands using SQL out of the database. Just access
sys.columns or whatever your particular database provides
(INFORMATION_SCHEMA or something). For each column, generate that line
that Ruby wants for a column / table entry. Then you can select as you
want for the Ruby app deleting unwanted column / table lines.

Does anyone have a definitive Ruby generation command for Nifty
using Ruby 4, for an existing database? I could generate the entire
thing via SQL, which I would be happy to provide.
