What are the best practices for error handling in Rails?

In Rails, best practices for error handling include using rescue blocks, custom error classes, and logging errors.

Can you explain how to use rescue blocks effectively?

Sure! Rescue blocks allow you to catch exceptions and handle them gracefully. You can specify which exceptions to rescue and provide fallback logic.

What about logging errors? How should I implement that?

You can use Rails' built-in logger to log errors. It's best to log at different levels (info, warn, error) based on the severity.

Are there any gems that can help with error handling?

Yes, gems like 'exception_notification' can help you send notifications when errors occur, and 'better_errors' can improve debugging.
