ActiveRecord Queries Aliasing
# Rails 4.0.13
items = ShippingItem.joins(shipment: :booking)
.joins("INNER JOIN (#{
ShippingItem.joins(shipment: :booking).select('max(booking.eta), shipment.dest_site_id').group('shipments.dest_site_id').to_sql
}) AS sub sub.dest_site_id = shipments.dest_site_id AND booking.eta = sub.max_eta")
.order(Shipment.arel_table[:dest_site_id])
# The outer query tables get automagically aliased (`shipments` `shipments_shipping_items`, `shipment_bookings` `shipment_bookings_shipments`)

ActiveRecord Auto Aliasing

-- this particular query fails because we join business_sites on shipments but shipments was aliased shipments_shipping_items
