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.
