hello all,

Is there some way to generate migrations from an existing database  
structure? I have the schema.rb file, but it isn’t enough for me. I  
need the migration files…

Please help!

schema.rb is as close as you’re going to get. You could always chop it  
up into migrations if you really wanted to (why?)
