- 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'.
In this lab, we will be creating a meal delivery service.
- 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:
new Neighborhood()- initialized withname. It returns an object that has attributes ofidandnamedeliveries()- returns a list of all deliveries placed in a neighborhoodcustomers()- returns all of the customers that live in a particular neighborhoodmeals()- returns a unique list of meals that have been ordered in a particular neighborhood (you might want to do this one last)
new Customer()— should expect to be initialized with a name and a neighborhoodId. It returns an object that has attributes ofid,neighborhoodId, andname.deliveries()— returns all of the deliveries that customer has receivedmeals()- returns all meals that a customer has orderedtotalSpent()- returns the total amount that the customer has spent on food.
new Meal()— initialized withtitleandprice. It returns an object that has attributes oftitle,price, andid. 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 thestatickeyword to write a class method.
new Delivery()— initialized withmealId,neighborhoodId, andcustomerId. It returns an object that has attributes ofmealId,neighborhoodId,customerId, andidmeal()- returns the meal associated with a particular deliverycustomer()- returns the customer associated with a particular deliveryneighborhood()- returns the neighborhood associated with a particular delivery
