Rails - Sep 2005 - Updating DB Schema

If you update your database schema will Rails automatically recognize  
the changes? For instance, if you add columns to an existing table  
that already has a model associated with it, will Rails need to be  
told of the changes?

If not, how do you incorporate the changes into your Rails app,  
without blowing away any existing configuration you''ve done?

Thanks,
Nathan

Rails will automatically recognize the new columns.  However, if you
create specific attribute readers / writers, those will not be updated
automatically.

Rails will automatically recognize changes you make to the database.
However, if you used scaffolding you will need to re-run the scaffolding
script or make the changes manually to your views.
