How can I debug Active Record issues in my Rails application?

To debug Active Record issues, start by checking the logs for any error messages. You can also use rails console to test queries.

If there are no errors in the logs, try using ActiveRecord::Base.logger = Logger.new(STDOUT) to get more detailed output.

Are there any tools that can help with debugging?

How can I optimize my Active Record queries?

You can optimize queries by using select to limit fields, includes to avoid N+1 queries, and where to filter results.
