nuby : adding new fields to existing table

Hi, I am starting rails with the clean slate(no legacy tables).I created tables and fields in sqlite using a gui.I am more comfortable this way.I did rake db:migrate. this updated the scheme.rb .After which I created Model .This basically has the same set of field as in scheme.rb for the table. But now when I want new field to the table in sqlite how should go about telling rails to update the scheme.rb and 001_create_table.rb file .Or should I do it manually. what is the normal way of doing this migration.Should I start from rails and it will create the table for me .... THnks Chinna

When you run "rake db:migrate", your schema.rb will get updated, and it will run any migrations that haven't been run.
