seed ride table
For scoped uniqueness constraints, you can put it on just one of the fields.  Also, the validations should be indented just one tab:

```ruby
class Ride < ActiveRecord::Base
  belongs_to :bus

  validates :timeframe, presence: true
  validates :direction, presence: true
  validates :day, presence: true
  validates :bus,
    presence: true,
    uniqueness: { scope: [ :timeframe, :day, :direction ] }
end
```
