To download the dependencies for backend, run:

bundle install

There is some starter code in the db/seeds.rb file so that once you've generated the models, you'll be able to create data to test your application.

You can run your Rails API on localhost:3000 by running:

rails s

There are no tests for this application, so you'll need to check your progress by running the server and using Postman make requests.

We're going to build an API for an apartment management company. Create the following database structure. You will have three models (and their corresponding tables), Apartment, Tenant and Lease, with the following relationships:

• A tenant has many apartments and has many leases
• An apartment has many tenants and has many leases
• A lease belongs to an apartment and belongs to a tenant

The models should have the following attributes (along with any attributes needed to create the relationships defined above):

• Apartment
  • number
• Tenant
  • name (must be present)
  • age (must be >= 18)

Make sure to define validations for your models so that no bad data can be saved to the database.

As a user, I can:

• Create, read, update and delete Apartments
• Create, read, update and delete Tenants
• Create and delete Lease

Follow good API design practices and use RESTful routing conventions. Make sure to handle errors and invalid data by returning the appropriate status code along with a message.
