Practice Code Challenge - Pet Shelter

Introduction

A local pet shelter has tapped you to build their database and connect it with Active Record.

Getting started

Relationship

• What associations will this need?
• (i.e. has_many, has_many through, and belongs_to)

Shelter

• Shelter#pets returns all pets associated with the shelter
• Shelter#adopters returns all the people who have adopted from this shelter
• Shelter#current_pets returns only the pets associated with the shelter who haven't been adopted
• Shelter#adopted_pets returns only the pets associated with the shelter who have been adopted

Pet

• Pet#shelter returns an instance of the shelter that pet is associated with
• Pet#adopter returns an instance of the person who adopted the pet, if any
• Pet.oldest returns the oldest pet by age
• Pet.average_age returns the average age of all pets
• Pet#in_dog_years returns the age in dog years of a pet if their species is dog (one human year is roughly five dog years and yes I know this is a gross oversimplification)

Adopter

• Adopter#pets returns all pets adopted by this person
• Adopter#shelters returns every shelter the person has adopted from
• Adopter#full_name returns the adopter's combined first and last names
• Adopter#adopt(pet) takes in an instance of a Pet, changes the pet's adopted? status to true, and associates the pet with the adopter if they're not already adopted
• Adopter#fav_pet returns the type of pet (species) they've adopted most of or nil if they've adopted no pets

Reminder

Even older pets need love!
