I’m using Windows XP SP2, Ruby 1.8.6 patch 111, Rails 1.2.3

When ever I run $ruby script/generate model someModel  
or $ruby script/generate migration someMigration  
I get migration files that are always prefixed with 001 instead of  
incrementing with each new migration creation. Any suggestions would  
be appreciated 😃

omg, I feel like such an ass. I spent hours digging through the rails  
source printing out variables and hard coding strings, which  
eventually showed me that @mirgation\_directory is relative from where  
you run the generator. Since I has cd’d into myapp/script it was  
looking for db/migrate inside of myapp/script. So to any newbies out  
there who run into this problem stay in your app root directory when  
calling the generate script.
