Hi all,

I have migrated with some tables in my application. After some days i
need to add few more tables to database. The initial tables in database
have some data. when i try to migrate the database for second time with
rake db:migrate it is saying the alredy table exist

and
rake is aborted. i dont want to loose the old data and i want to add new
tables to alredy exiested database

how to do this. Please help me.

Regards,
Rajkumar.

Care to post your migration script?

I suspect you might be creating a table instead of doing a 'add_column"
