ActiveRecord callbacks

Add callbacks

• username validation should fail both for :username => :admin and :username => 'admin' (always work with symbol)
• username should be saved and validated "downcased"

Add controller (and routes) for users

• index: show all users template
• show: show user info template

Add gems

• 'sextant'
• 'hirb'
• 'faker'

Misc

If you want to generate users for testing, add this to User model:

def self.random_user
  User.create(
    first_name: Faker::Name.first_name,
    last_name: Faker::Name.last_name,
    age: rand(18..100),
    username: Faker::Name.first_name.downcase
  )
end

Run from console with: 100.times { User.random_user }
