Audit.Net 不跟踪新值

Question

尝试在使用 .Net Core 和 EF Core 的项目中实施 Audit.Net

示例上下文定义为

  [AuditDbContext(Mode = AuditOptionMode.OptOut, IncludeEntityObjects = true, AuditEventType = "{database}_{context}")]
    public class MyContext : AuditDbContext
    {....

主方法有这个启动代码

using (var scope = host.Services.CreateScope())
            {
                var services = scope.ServiceProvider;
                try
                {
                    var context = services.GetRequiredService<MyContext>();
                    DbInitializer.Initialize(context);

                    Audit.EntityFramework.Configuration.Setup()
                        .ForContext<MyContext>(config => config
                            .IncludeEntityObjects()
                            .AuditEventType("{context}:{database}"))
                        .UseOptOut()
                            .IgnoreAny(t => t.Name.EndsWith("History"));
                }....

那么更新代码就是

var personToUpdate = await _context.People.FirstOrDefaultAsync(p => p.ID == id);
using (var audit = AuditScope.Create("Person:Update", () => personToUpdate ))
{
              
                personToUpdate.FirstName = "audited";
                _context.SaveChanges();
              
}

保存更改后，auditscope.event.target.new 为空

不太确定我错过了什么

Answer 1

您无需创建AuditScope，Audit.EntityFramework 库将在内部创建AuditScope。您只需拨打SaveChanges()

var personToUpdate = await _context.People.FirstOrDefaultAsync(p => p.ID == id);
personToUpdate.FirstName = "audited";
_context.SaveChanges();
