Use Hashids (http://hashids.org/ruby/) in your Rails app ActiveRecord models.
The Hashid RailsGem is an innovative solution for Ruby on Rails applications that simplifies the way identifiers are managed within your models. Instead of using plain sequential IDs, this gem generates unique, short hash strings, enhancing both the security and aesthetics of your application URLs. With its ability to smoothly integrate into existing systems, developers can upgrade their models without needing to undergo a major overhaul.
What sets Hashid Rails apart is its versatility and ease of use. The underlying database continues to use integers for records, allowing for a seamless transition to hash IDs. This gem is particularly valuable for developers looking to enhance URL readability or obfuscate sensitive identifiers, all while maintaining robust backend functionality.
Unique Hash Generation: Converts sequential IDs into short, unique hashes like "yLA6m0oM," ensuring identifiers are not easily guessable.
Database Compatibility: Maintains integer IDs in the database, offering the flexibility to install or uninstall the gem without impacting existing records.
Simple Installation: Easily add to your Rails application by including it in your Gemfile and executing a single command.
Model Integration: Simply include Hashid Rails in your desired ActiveRecord models, allowing immediate use of hashids throughout your application.
Customizable Configuration: Offers options to customize hashid settings at both the application and model level for tailored behavior.
Find by Hashid: Provides the Model#find_by_hashid method for fetching records using hashids, ensuring compatibility with existing methods that utilize implicit IDs.
Upgrade Support: Includes guidelines for transitioning from pre-1.0 versions while maintaining hashid consistency, alongside detailed configuration updates.
Development-Friendly: Equipped with commands to set up the local development environment, making it easy for contributors to engage with the codebase.

Ruby on Rails, often referred to as Rails, is an open-source web application framework written in Ruby. Known for its convention over configuration and don't repeat yourself (DRY) principles, Rails simplifies and accelerates the development of database-backed web applications.
