    ABP CLI 和 SUITE的版本是? 错误日志是?

    ABP CLI 是 最新的版本 abp suite update --p 没有看到错误日志,代码到这里就报错了(通用内部方法,调试不了) return await _projectTaskRepository.UpdateAsync(projectTask);

    您直接生成代码试试就知道了,只要是导航的多对多关系,只要做了删除操作,保存时就一定会报错的。

    你用abp suite 可以复现的。没有改动任何代码。

    App logs:

    YourWebHostProject/Logs/logs.txt

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

    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

    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。

    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

    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?
