CONVENTIONS.md file for AI Rails 8 development
  • You MUST NOT try and generate a Rails app from scratch on your own by generating each file. For a NEW app you MUST use rails new first to generate all of the boilerplate files necessary.
  • Create an app in the current directory with rails new .
  • Use Tailwind CSS for styling. Use --css tailwind as an option on the rails new call to do this automatically.
  • Use Ruby 3.2+ and Rails 8.0+ practices.
  • Use the default Minitest approach for testing, do not use RSpec.
  • Default to using SQLite in development. rails new will do this automatically but take care if you write any custom SQL that it is SQLite compatible.
  • An app can be built with a devcontainer such as rails new myapp --devcontainer but only do this if requested directly.
  • Rails apps have a lot of directories to consider, such as app, config, db, etc.
  • Adhere to MVC conventions: singular model names (e.g., Product) map to plural tables (products); controllers are plural.

JWT Auth + Refresh Tokens in Rails

JWT Auth + Refresh Tokens in Rails

This is just some code I recently used in my development application in order to add token-based authentication for my api-only rails app. The api-client was to be consumed by a mobile application, so I needed an authentication solution that would keep the user logged in indefinetly and the only way to do this was either using refresh tokens or sliding sessions.

I also needed a way to both blacklist and whitelist tokens based on a unique identifier (jti)

Before trying it out DIY, I considered using:
