Question 1

How to deploy a Rails app to a cloud server?

Accepted Answer

Use platforms like Heroku, AWS Elastic Beanstalk, or Docker containers. Rails applications typically require a web server like Puma, a database setup, and environment configuration. The Rails Guides provide detailed deployment instructions for various environments.

Question 2

Rails vs Django: which should I choose?

Accepted Answer

Both are full-stack frameworks, but Rails uses Ruby and emphasizes convention, while Django uses Python and offers more flexibility. Choose Rails if you prefer Ruby's syntax and rapid development, or Django if you need Python's data science libraries or a more explicit configuration.

Question 3

How to handle file uploads in Rails?

Accepted Answer

Use Active Storage, which is integrated into Rails for handling file attachments to cloud services or local storage. It supports direct uploads, image processing, and is configured via Rails generators, as mentioned in the README's feature list.

Question 4

What's the best way to manage background jobs in Rails?

Accepted Answer

Rails includes Active Job, a framework for declaring and running background jobs with support for multiple queuing backends like Sidekiq or Resque. Set up a queue adapter and define job classes to offload time-consuming tasks.

Question 5

How to add real-time features to a Rails app?

Accepted Answer

Use Action Cable, Rails' WebSocket framework, to implement features like chat or notifications. It integrates seamlessly with the MVC structure and is included in the standard Rails installation, as noted in the README.

Question 6

Rails or Node.js for building a REST API?

Accepted Answer

Rails is faster for conventional APIs with its built-in serializers and routing, while Node.js offers better performance for I/O-heavy operations. If you need rapid development and follow REST conventions, Rails is ideal; for high concurrency with non-blocking I/O, consider Node.js.
