How can I handle errors and logging in Ruby?

In Ruby, you can use the begin-rescue block for error handling. For logging, the Logger class is very useful.

Can you show me a simple example of using begin-rescue?

Sure! Here's a basic example:

begin
  # code that might raise an error
  result = 10 / 0
rescue ZeroDivisionError => e
  puts "Error: #{e.message}"
end

What about logging? How do I set that up?

You can set up logging like this:

require 'logger'
logger = Logger.new('application.log')
logger.info('This is an info message')
logger.error('This is an error message')

How can I log exceptions that occur in my code?

You can log exceptions in the rescue block like this:

begin
  # code that might raise an error
rescue => e
  logger.error("Exception occurred: #{e.message}")
end
