UPDATE 语句与 asp.net mvc 中的 FOREIGN KEY 约束冲突 [关闭]
Posted
技术标签:
【中文标题】UPDATE 语句与 asp.net mvc 中的 FOREIGN KEY 约束冲突 [关闭]【英文标题】：The UPDATE statement conflicted with the FOREIGN KEY constraint in asp.net mvc [closed] 【发布时间】：2021-10-18 17:36:13 【问题描述】：我知道有很多类似的问题，但没有一个可以帮助我解决这个问题。我只是想将 WC_Inbox 表中记录上的Status 的值从Pending 更改为Archived，但我收到了这个错误。我在这里问的主要原因是因为我不明白外键与我要执行的操作有什么关系。

在我的 SQL 数据库中，员工 ID 列上的外键关系已设置为 Cascade，正如在类似帖子中提到的那样。
我还能尝试解决这个问题吗？

【参考方案1】：尝试在隐藏字段中使用模型，因为 ViewBag 数据不会被回发
@Html.HiddenFor(model => model.EmployeeID)
@Html.HiddenFor(model => model.Add_User)
@Html.HiddenFor(model => model.Date_Added)
并从操作中删除绑定，因为恕我直言，您不需要它
public ActionResult Work( WC_Inbox wC_Inbox)
