As far as I know, the only thing you need to change is database.yaml.
So I set up it, changing adapter from mysql to sqlite and pointing to
the file, which should play a role of database. Now when I try to run
rake db:create an error pops up saying "Could not find table 'users'".
Why's that and how to override this? By logic, db:create is only
creating a blank database, without any table in it. So, what's the
deal with tables then?
