How can I handle errors in a Ruby on Rails application?

In Ruby on Rails, you can handle errors using rescue blocks, custom error pages, and middleware.

Can you give me an example of using a rescue block?

Sure! You can wrap your code in a begin-rescue block like this:

begin
  # code that might raise an error
rescue SomeError => e
  # handle the error
end

What about custom error pages?

You can create custom error pages by adding HTML files in the public directory, like 404.html for not found errors.

Is there a way to log errors in Rails?

Yes, Rails automatically logs errors to the log files in the log directory. You can also use tools like Sentry for better tracking.
