我有一个带有 2 个连接的价格功能，当我使用它来调用价格时，它工作得很好而且很花哨。但是现在当我添加 Kaminari 以便能够分页时，它给了我一个错误，我想知道我是否可以自定义 Kaminari 中的“count *”函数，或者是我调用产品的函数出错了？
这是在我的控制器中
@prices = Price.select("`prices`.*").joins(:retailer, :retailer => :profile).
where(['product_id=? AND size_id=?', params[:prod_id], params[:si_id]]).
group(:retailer_id).order("SUM((prices.price * #{params[:amount].to_i}) + profiles.shippingCost)").page(params[:page])
错误代码：
Mysql2::Error: Column 'retailer_id' in field list is ambiguous: SELECT COUNT(*) AS count_all, retailer_id AS retailer_id FROM `prices` INNER JOIN `retailers` ON `retailers`.`id` = `prices`.`retailer_id` INNER JOIN `profiles` ON `profiles`.`retailer_id` = `retailers`.`id` WHERE (product_id='1' AND size_id='3') GROUP BY retailer_id,retailer_id ORDER BY SUM((prices.price * 1) + profiles.shippingCost)
当我调用没有 Kaminari 的产品时，MYSQL 看起来像这样。
SELECT `prices`.* FROM `prices` INNER JOIN `retailers` ON `retailers`.`id` = `prices`.`retailer_id` INNER JOIN `profiles` ON `profiles`.`retailer_id` = `retailers`.`id` WHERE (product_id='1' AND size_id='3') GROUP BY retailer_id ORDER BY SUM((prices.price * 1) + profiles.shippingCost)
提前致谢！
