基于Ruby关联模型属性的模型排序记录

Question

我有一个库存模型和一个供应模型，而库存属于供应模型。

我想根据供应模型的“ date_received”属性对库存记录进行排序

Stock.where("seller_id = ? AND status = ? AND product_id = ?", @seller_id, "Approved", list_item.product_id)

我在以下方面遇到错误：

Stock.includes(:supply).where("seller_id = ? AND status = ? AND product_id = ?", @seller_id, "Approved", list_item.product_id).order("supply.date_received")

Answer 1

应该是supplies而不是supply试试，

Stock.includes(:supply).where("seller_id = ? AND status = ? AND product_id = ?", @seller_id, "Approved", list_item.product_id).order("supplies.date_received")
