hi

Please use English to describe the problem. Our suite colleagues will check the problem.

ABP Framework version: v8.0.1

UI Type: MVC

Database System: EF Core (SQL Server

Tiered (for MVC) or Auth Server Separated (for Angular): no

Exception message and full stack trace:

Steps to reproduce the issue:

1、use abp suite build entity A，Master type 2、use abp suite build entity B，Child type，set parent is A 3、run system. Create A ， And then Create B，but the B save button is no response

when I search in my application the word $(this).data("projectFlowing-id") and replace the projectflowing placeholder with your entity name as lowercase. the save function can response, but has one inner exception.

2024-01-11 17:44:13.980 +08:00 [ERR] An error occurred while saving the entity changes. See the inner exception for details. Microsoft.EntityFrameworkCore.DbUpdateException: An error occurred while saving the entity changes. See the inner exception for details. ---> Microsoft.Data.SqlClient.SqlException (0x80131904): INSERT 语句与 FOREIGN KEY 约束"FK_AppFlowingReports_AppProjectFlowings_ProjectFlowingId"冲突。该冲突发生于数据库"ProjectReward"，表"dbo.AppProjectFlowings", column 'Id'。 语句已终止。

AppProjectFlowings is Parent Table。 AppFlowingReports is child Table。

多谢，问题已解决。

你好

你改成DeleteBehavior.Cascade, 之后添加新迁移, 数据库就可以了

谢谢，是不是abp suite 生成代码时，不要勾选 数据库迁移，在生成代码之后，在解决方案里边，找到生成的代码，改为 DeleteBehavior.Cascad，然后设置 迁移项目为启动项目，执行迁移的方式即可？

这是EF Core 8 的一个bug

请关注 https://github.com/dotnet/efcore/issues/32383

我会尝试找一个解决方案

好的，感谢大神，期待早日解决。

这是我的到的错误日志

错误日志在哪里能看到，我从YourProjectWebHost目录的 logs文件夹打开的log文件，是没有这个信息的。另外，这个错误有什么处理建议吗

ABP Framework version: v8.0.1

UI Type: MVC

Database System: EF Core (SQL Server

生成的代码，选择 ApplicationTemplate，MVC，MS SQL SERVER 数据库

请你花几分钟， 1、使用abp suite 创建A对象，关联B对象（多对多导航关系）， 2、运行代码 3、创建A对象时，关联选择一个或者多个B对象， 4、编辑A对象，把其中的B对象删除一个，点击保存，报错。

App logs:

YourWebHostProject/Logs/logs.txt

Suite logs: C:\Users\usernmae.abp\suite\logs

查看了，操作后，发现日志没有记录任何报错信息

你先分享一下内部服务器错误的日志.

你用abp suite 可以复现的。没有改动任何代码。
