What are the best practices for error handling in Rails?

In Rails, it's important to handle errors gracefully. Some best practices include using rescue blocks, custom error pages, and logging errors for debugging.

Can you explain how to use rescue blocks effectively?

Sure! Rescue blocks allow you to catch exceptions and handle them without crashing your application. You can specify which exceptions to rescue and provide fallback logic.

What about custom error pages? How do I set those up?

You can create custom error pages by adding HTML files in the public directory for specific HTTP status codes, like 404.html or 500.html.

How can I log errors for debugging?

Rails automatically logs errors to the log files in the log directory. You can also use tools like Sentry or Rollbar for more advanced error tracking.
