问题描述
我的用户表包含：PK-ID，用户名，密码。 我有三张桌子（笔记本电脑，显示器，电话）-ID-FK，系列，型号 我有userequipmentmapping表，其中包含：id-PK，user_id-FK（来自用户表的ID），laptop_id-FK（来自笔记本电脑表的ID），phone_id-FK（来自电话表的ID），display_id（来自dislpay表的ID），start_date，结束日期。
我想通过UserEquipmentMapping在gridview中按用户搜索，但是考虑到用户名是通过外键从users表传递的，所以我不知道应该在哪里实现搜索模型。 如有任何建议，我们将不胜感激。预先谢谢您！

解决方法
在索引视图_search视图中取消注释。来自UserequipmentmappingSearch模型的所有字段。您可以将输入字段替换为用户，笔记本电脑等的选择字段。搜索模型将做另一件事，所有操作都在填充数据提供者的搜索功能中
