Print Instead Of Logger (ARCH6157)

Key ruby.logging.puts-instead-of-logger · Severity warning · Category logging

Writing to stdout with puts or print lacks log levels, timestamps, and a configurable sink. Production code should use the framework logger.

Incorrect

def charge(order)
  puts "Processing order #{order.id}"
  gateway.charge(order)
end

Correct

def charge(order)
  Rails.logger.info("Processing order", order_id: order.id)
  gateway.charge(order)
end

Fix

Use Rails.logger or a configured Logger instance instead of puts/print.
