Thank you very much! I thought I did something wrong.

bert_a: You must be running Rails 2.1 or higher, as this is the new way the migration numbering works. That large number is a timestamp, which stops the problem that occurs when two developers create a new table separately and end up with clashing migration numbers.

I’m not aware of a plugin that reverts it (That doesn’t mean it doesn’t exist though!)

Simply Rails 2 (and all of the other rails books I have) shows the migration file naming convention is
001, 002, etc

When I ran script/generate model User, the migration file was named:
20081110174511_create_users.rb

Why does it have this complex number instead of 001? Is there a way to
redo this and get the simpler name?
