我通过为 req.user 提供一个实例在服务器上进行身份验证cds.User
,并添加了一些属性:
User {
id: '110226363079182595683',
attr: { name: 'depth1', email: 'depth1@protonmail.com' },
_roles: { 'identified-user': true, 'authenticated-user': true }
}
这允许我使用经过身份验证的用户调用我的 CDS 服务。
它运作良好。
然后,我在我的 CDS 模式中有一个实体:
entity Comments {
key ID : Integer;
project : Association to Projects;
title : String;
text : String;
CreatedBy : String @cds.on.insert : $user;
CreatedByName : String @cds.on.insert : $user.name;
}
我在 SQLite 数据库上的架构。我启动了服务器,我启动了一个 UI5 应用程序,它允许在 OData V4 中插入评论,这就是发生的事情:

在我的数据库中,CreatedBy
已填充但未填充CreatedByName
。同样在创建请求中,我得到了CreatedByName
服务器的填充并返回它真的很奇怪。
我怎样才能cds.User
在数据库中插入一些属性?!谢谢 !
