Rails - Mar 2006 - simple migration problem

Hi:

I''m running RoR 1.1

I''m going through the Agile book Depot example and I want to generate
my
next migration file so i''m typing

./script/generate migration depot

I was sort of expecting to get the file 002_depot.rb .. instead i''m 
being informed that there already exists a migration named depot..and no 
new file is generated..

should I be using a new name? I tried that accidentally and got 
002_help.rb

?

The agile book came out while migrations were a work in progress, so it 
doesn''t really cover this.

If you look at the file you create you will notice that the migration 
creates a class with a name the same as you gave in the migration:

class Products < ActiveRecord::Migration
...
end

this is without the 001_ or 002_, so you would have a clas name conflict 
if you use the same name twice.

Here is a link to some docs:

Different name definitely.

To get help, just leave out the final arg:
./script/generate migration

Did you know that if you generate model Foo that it will create the  
migration for create_foos automatically?

Thank you Rob and Sean... the class name argument makes perfect sense.

cheers!
