前端用户表性别字段不显示，Postman请求正常网页提交失效求助

我创建了用户表，所有功能运行正常，仅性别字段无法正常填充：通过Postman发起POST请求时，性别可以按预期显示，但通过网站前端创建用户后，表格中仅展示邮箱、姓名、激活/禁用状态，性别位置为空，我无法定位问题所在，相关代码如下：

问题核心为字段名不匹配：
表单里性别单选框的name属性设置为Lytis（立陶宛语“性别”的意思），但数据库存储、后端接口接收以及表格渲染用的字段名是gender。Postman请求时直接传了gender字段，所以能正常入库显示，但前端提交表单时，提交的是Lytis字段，后端接口没有对应处理这个字段，所以性别数据没有被存入数据库，表格渲染时自然为空。

修复步骤： #

1. 修改update user.ejs里两个性别单选框的name属性，把Lytis改为gender：

<input type="radio" id="radio-2" name="gender" value="Vyras" <%= user.gender =='Vyras'? 'checked' :''%>>
<input type="radio" id="radio-3" name="gender" value="Moteris" <%= user.gender =='Moteris'? 'checked' :''%>>

2. 找到新增用户页面add-user.ejs，同样把性别单选框的name属性从Lytis改为gender即可。
