• Validations are useful for controlling or limiting what gets saved from a form to a database.
• We'll add validations to ensure each form field has input.

###app/models/contact.rb

class Contact < ActiveRecord::Base
  validates :name, presence: true
  validates :email, presence: true
  validates :comments, presence: true
end

###Terminal

git add .
git commit -m "Added form validations to model"
git push origin contact_form
