set_redirect_status.rb

# Add "status: :see_other" to redirects without explicit redirect status
#
# This is useful for migration to Turbo: https://turbo.hotwired.dev/handbook/drive#redirecting-after-a-form-submission
#
# Usage:
#
# ack redirect_to app/controllers | cut -f 1 -d : | sort -u | while read FILE; do ruby set_redirect_status.rb $FILE; done
