Another question about migrations.

When I type:

# =========== rake migration VERSION=1

The value in the schema table change to ‘1’ but none of the down  
commands are issued to drop the respective tables. Am I doing  
something wrong here?

Thanks 🙂

For some reason it is working now. Maybe it was related to my  
previous problem. Thanks.
