I’m working through chapter 6 and I made a typo in the ruby script/generate command. I tried to fix it by using rake db:migrate VERSION=0, but then my app produced an error. Then I tried to delete the whole project directory and start over, but now I’m getting an error when running rake db:migrate on page 77. Is there some way I can just start over and zero everything out? I don’t want to mess with fixing it I just want to dump the depot project and related database stuff and start over.
