`where.first`じゃなくて`find_by`使った方が綺麗だったりしない？

```
[2] pry(main)> Album.where(id: 1).first
  Album Load (6.1ms)  SELECT `albums`.* FROM `albums` WHERE `albums`.`id` = 1 ORDER BY `albums`.`id` ASC LIMIT 1
=> #<Album id: 1, user_id: 1, name: "A1", created_at: "2013-09-02 06:42:24", updated_at: "2013-09-02 06:42:24">
[3] pry(main)> Album.find_by(id: 1)
  Album Load (0.5ms)  SELECT `albums`.* FROM `albums` WHERE `albums`.`id` = 1 LIMIT 1
=> #<Album id: 1, user_id: 1, name: "A1", created_at: "2013-09-02 06:42:24", updated_at: "2013-09-02 06:42:24">
