ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: in rails query

Question

您好，我已经包含了给定的代码

 Spree::Order.includes(:ship_address).where('ship_address.country_id = ?', 52).references(:spree_address).count

我遇到了给定的错误

 (1.1ms)  SELECT COUNT(DISTINCT "spree_orders"."id") FROM "spree_orders" LEFT OUTER JOIN "spree_addresses" ON "spree_addresses"."id" = "spree_orders"."ship_address_id" WHERE (ship_address.country_id = 52)

签到大礼包model

belongs_to :ship_address, foreign_key: :ship_address_id, class_name: 'Spree::Address'
    alias_attribute :shipping_address, :ship_address

请指导我如何解决这个错误。
