Adding composite index to pre-existent table

rubyonrails-talk

Hello everybody, I'm a newbie in RoR. In order to create a table I've created a migration with the 'rails generate model...' command. Now I would like to add a composite index over two columns of this table with another, new, migration. Is it possible? I've read the documentation about the add_index transformation but I can't create the new migration from command line. I think I can edit the 'create table' migration file, but I would like to have a different migration (generated by 'rails' command).

Thanks in advance for your help,

Federico

of course

rails generate migration do_blah will create a new migration called do_blah
