Update to Rails 3.2.16. Also a bundle update
Add public/uploads_test to .gitignore
Remove public/uploads_test after rspec run
Change unless/else to if/else in app/views/buy_photos/buy.html.slim
Correct layout for printing
Use .pluck(:name) instead of .map(&:name) on app/views/buy_photos/buy.html.slim

This loads only name on SQL and returns an array

SELECT "students".* FROM "students" INNER JOIN "parentages" ON "students"."id" = "parentages"."student_id" WHERE "parentages"."parent_id" = x
->
SELECT "students"."name" FROM "students" INNER JOIN "parentages" ON "students"."id" = "parentages"."student_id" WHERE "parentages"."parent_id" = x
Add simplecov

Now: 252 / 377 LOC (66.84%)
Review tests and add another basic model tests
Move @buy_photos logic into BuyPhoto model

Well, move logic from view to model
`BuyPhoto::PRICE * @buy_photos.count` into BuyPhoto.price.
in app/views/buy_photos/buy.html.slim
