Assignment

Create a contact list app. Users should be able to create, edit, update, and destroy contacts.

Via API AND UI, you should be able to:

• CRUD contacts
• Request contacts with sorts:
  • in alphabetical order
  • in reverse alphabetical order
  • by creation date
  • by creation date in reverse order

UI should offer an index page, a show page, and forms to edit a Contact. There should also be a delete button.

A Contact is:

• First name, required
• Last name, optional
• Phone Number, required

Validations

• A name can contain letters or a dash or a space
• Must be a phone number with optional country code
• Phone number cannot contain spaces, dashes, or parens
• No uniqueness validation for phone number or name

Bonus

• User can input phone number with parens, spaces, dash but it is stored as a flat number string with country code.
• If you try to enter two users with the same phone number, show a warning message.
