Sql 活动记录和操作员

如何将此转换为一个WHERE语句？我想找一份记录，其中一处房产是公寓，也可出售

def apartment
    @apartments_for_sale = Property.where(for_sale: true)
    @real_apartments = @apartments_for_sale.where(apartment: true)
end

---

非常感谢

您应该能够做到：

def apartment
    @apartments = Property.where(for_sale: true, apartment: true)

     #OR via method chaining:

    @apartments = Property.where(for_sale: true).where(apartment: true)
end
