I already generated a class by "script/generate model blah blah1:string"
How would I add a "blah2:string" to the existing model? Is there a script or do I have to manually edit the database and every file?
A:
You can create new migration of change table.. Check this.. See section 3.2

I read that, I'm not sure where I enter the code. Do I create a new file with the code in it and execute it with Ruby?

Create a migration and your code in that migration. Run the rake task to execute it

A:
Create migration:
./script/generate migration AddBlah2ToBlah blah2:string
This will create migration in db/migrate ruby file with migration - you can check if it correctly added column to table. Then run:
rake db:migrate
or in production environment:
rake db:migrate RAILS_ENV=production
This will add column to your database and you can use it in Rails:
@blah = Blah.first
@blah.blah2 = "new string"
...
