-----5/14/2017----- It is better to use Recipe.where ("prep_time > ?", 10) than Recipe.where("prep_time > 10") because sometimes user does not enter 10 as prep_time, but some strings or something else. That's why we need to check user's input first. localhost:3000?sort=prep_time => sort the index page by prep_time (asc order) 85% of jobs applicants got jobs through referrals.
