Daily Lunch Lab

Objectives

  • Build a domain model with class relations using JavaScript iterator methods
  • Use JavaScript to answer questions about data stored in our application
  • In this lab, we're using a global store variable to manage application state; it's our frontend 'database'.

Instructions

In this lab, we will be creating a meal delivery service.

The Domain

  • A meal has many customers
  • A delivery belongs to a meal, belongs to a customer, and belongs to a neighborhood
  • A customer has many deliveries
  • A customer has many meals through deliveries
  • A customer belongs to a neighborhood
  • A neighborhood has many deliveries
  • A neighborhood has many customers through deliveries
  • A neighborhood has many meals through deliveries

Please note: the tests do not check these methods in order. Some of these methods rely on the relationships between classes to be working already. Use the tests as a guide and refer to this reading if you need more information about what a method is supposed to be doing.

You will be modeling the following:

Neighborhood class:

  • new Neighborhood() - initialized with name. It returns an object that has attributes of id and name
  • deliveries() - returns a list of all deliveries placed in a neighborhood
  • customers() - returns all of the customers that live in a particular neighborhood
  • meals() - returns a unique list of meals that have been ordered in a particular neighborhood (you might want to do this one last)

Customer class:

  • new Customer() — should expect to be initialized with a name and a neighborhoodId. It returns an object that has attributes of id, neighborhoodId, and name.
  • deliveries() — returns all of the deliveries that customer has received
  • meals() - returns all meals that a customer has ordered
  • totalSpent() - returns the total amount that the customer has spent on food.

Meal class:

  • new Meal() — initialized with title and price. It returns an object that has attributes of title, price, and id. Meal Ids should automatically increment.
  • deliveries() - returns all of the deliveries associated with a particular meal.
  • customers() - returns all of the customers who have had the meal delivered. Be careful not to return the same customer twice if they have ordered this meal multiple times.
  • byPrice() - A class method that orders all meal instances by their price in descending order. Use the static keyword to write a class method.

Delivery class:

  • new Delivery() — initialized with mealId, neighborhoodId, and customerId. It returns an object that has attributes of mealId, neighborhoodId, customerId, and id
  • meal() - returns the meal associated with a particular delivery
  • customer() - returns the customer associated with a particular delivery
  • neighborhood() - returns the neighborhood associated with a particular delivery
