Introduction to Advanced Enum Techniques #

Now that we've covered the basics of defining and using enums in Rails 8, it's time to explore advanced techniques that make enums even more powerful.

Rails 8 introduces enhancements that improve the way developers interact with enums, providing better performance, maintainability, and flexibility.

In this chapter, we will cover:

• Using scopes and custom queries with enums.
• Implementing multiple enums in a single model.
• Dynamically updating enums without breaking existing records.
• Using enums in API responses (serialization techniques).
• Handling deprecated enum values safely.

By the end of this chapter, you'll have a deep understanding of how to maximize enums in real-world Rails applications.
