Easy Rails controller rate limiting with Rails.cache

15-Nov-2024 116
This makes use of Rails.cache to store a key for 20 seconds. If the method is hit again while the key exists, we return an error. Otherwise we allow the operation to complete. This is a quick and easy way to add a simple rate limit to a controller. For more advanced scenarios I typically use Rack Attack.
