It's very strange, but I saw this information in comments of generated schema.rb. # This file is auto-generated from the current state of the database. Instead of editing this file, # please use the migrations feature of Active Record to incrementally modify your database, and # then regenerate this schema definition. # # Note that this schema.rb definition is the authoritative source for your database schema. If you need # to create the application database on another system, you should be using db:schema:load, not running # all the migrations from scratch. The latter is a flawed and unsustainable approach (the more migrations # you'll amass, the slower it'll run and the greater likelihood for issues). # # It's strongly recommended to check this file into your version control system. > > > instead we should use schema.rb and seed.rb scripts.
