Rails seeds.rb種子檔案資料

ctrlp>db/seeds.rb種子資料
有了這個就不用一直登打資料了
# This file should contain all the record creation needed to seed the database with its default values.
# The data can then be loaded with the rails db:seed command (or created alongside the database with db:setup).
#
# Examples:
#
#   movies = Movie.create([{ name: 'Star Wars' }, { name: 'Lord of the Rings' }])
#   Character.create(name: 'Luke', movie: movies.first)
或是
u = User.new
u.email = "admin@test.com"           # 可以改成自己的 email
u.password = "123456"                # 最少要六码
u.password_confirmation = "123456"   # 最少要六码
u.is_admin = true
u.save
