To bootstrap a Rails API with PostgreSQL and JWT authentication, you scaffold a new project using the --api and --database=postgresql flags, then add bcrypt and jwt gems to handle token-based login and protected routes.

The best way to structure ActiveRecord associations in a new Rails app is using conventional MVC scaffolding, which sets up model relationships, validations, scopes, and common queries alongside RESTful controllers and migrations.

Yes, you can use this Rails scaffolding for a full-stack app with view rendering. It targets both API backends and full-stack projects, providing templates for models, controllers, routes, and view rendering alongside MVC architecture.

Yes, you need to install PostgreSQL before scaffolding a Rails application, along with a Ruby/Rails environment. The setup requires PostgreSQL to create and migrate the database for your models.

JWT token handling for protected routes in a Rails API works by using the bcrypt and jwt gems to issue tokens upon login, which are then required in request headers to authenticate and secure access to RESTful controller endpoints.

A limitation of using MVC scaffolding for Ruby on Rails applications is that it generates boilerplate models, controllers, and views, requiring manual customization of the service layer and business logic for complex user-generated content beyond standard REST APIs.
