This PR should have these lines removed, not commented out.

Also, see here where the db to connect to is set.  Otherwise, did you just mean to configure it not to connect to any db?

(not that I agree with the specific way this is done...)

```ruby
database_yml = File.expand_path('../internal/config/database.yml', __FILE__)
db_name = ENV['DB'] || 'sqlite3'
ActiveRecord::Base.configurations = active_record_configuration
config = ActiveRecord::Base.configurations[db_name]
ActiveRecord::Base.establish_connection(db_name)
ActiveRecord::Base.connection
```
