In the year 20XX, Inventables is expanding, aiming to capture the hot vehicle rental market for vacationing X-Carve owners. We've procured a sizable vehicle fleet and built a website allowing customers to make rental reservations. Initial customer feedback has been mostly positive, except that over the recent Election Day holiday weekend we took more reservations than we had vehicles in our fleet and were unable to fulfill some of the reservations!
We want you to help us update the app to ensure that we won't take more reservations than we can fulfill so that we don't run into this problem again.
The project is organized following Rails conventions, with model classes in app/models/, controllers in app/controllers/, and views in app/views/. Tests are in test/models/ and test/controllers/. The Rails routes file is config/routes.rb and the database schema is db/schema.db.
A particular category of vehicle. A vehicle category has a name, such as "SUV", "Sedan", or "Convertible", and a daily_price, in dollars, to rent a vehicle in that category.
As you will see below, we make reservations at the category level — that is, a customer will make a reservation for "a sedan" and we will fulfill it with any one of the sedans in our rental fleet.
A vehicle make and model. Each vehicle model belongs to a vehicle category. Vehicle models also have a make identifying the manufacturer, such as "Ford" or "Honda", and a name identifying the model name, such as "Focus" or "Pilot".
A specific vehicle from our rental fleet. Each vehicle belongs to a vehicle model. A vehicle also has a year, such as 2019 and a commissioned_on date when it was added to the rental fleet. A vehicle can be removed from the rental fleet by setting a decommissioned_on date.
A customer's vehicle reservation. A reservation belongs to a vehicle category, as mentioned above. A reservation also has a start_date and an end_date, and a total_price in dollars.
Implement validations in the Reservation model or the ReservationsController to prevent the Rentables app from creating reservations if its fleet doesn't have enough vehicles in the category to fulfill a reservation for the requested date range.
We've added some tests in test/integration/reservation_flow_test.rb covering creating reservations. One of these tests is failing — we need to get it to pass.
