ActiveRecord SQLite3 "unable to open database file"

I am starting up a Hobo based project that will appear sometime soon. I made a simple mistake, so I thought I should share.

I ran something like this... sudo hobo code_blog
I got a few missing gem problems, so I did a few sudo gem install X.
I did a few ./script/generate hobo_model_resource X.
Finally I get to ./script/generate hobo_migration
and ./script/server

With excitement I fire up firefox and get a lovely screen. I attempt to sign up and get

OK, so do you spot the mistake?

Well it's the sudo in sudo hobo code_blog.

This made the hobo files all owned by sudo.

The fix.. sudo chown nigelthorne code_blog/* obviously with your username and project directory.

We live a learn. :)
