How can I handle errors in Ruby on Rails?

In Ruby on Rails, you can handle errors using rescue blocks, custom error classes, and middleware. Would you like examples?

Yes, please provide an example of using rescue blocks.

Sure! You can use a rescue block like this:

begin
  # code that might raise an error
rescue StandardError => e
  puts "Error occurred: \\#{e.message}"
end

This will catch any StandardError and print the error message.

What about custom error classes?

You can create custom error classes by inheriting from StandardError. For example:

class MyCustomError < StandardError; end

Then, you can raise this error in your code when needed.
