sql.rb

  before do
    ActiveSupport::Notifications.subscribe('sql.active_record') do |name, starts_at, ends_at, id, payload|
      if /stock_items/.match(payload[:sql]) && /INSERT/.match(payload[:sql])
        puts caller.delete_if { |p| !p.include?("/Users/ryan/Sites/gems/spree") }.join("\n")
        puts "*" * 100
      end
    end
  end
  

This is simple and clever.

Where do you put this ?
Given it's a AS::N subscribe block I would have put it in an initializer, but the before block is not familiar.

Thanks
