Title: Code review

I wanted to give you some input on what you have so far.
* Provide example config files for other developers (.env, config/database.yml).
* Having a unique index on city name will be problematic.
* Keep your factories simple. Don't use `rand(n)`. Drop your test db after making these changes.
* Avoid using `_id or .id`. Use the active record object instead.
