在我的审计上设置AuditReport并保存后,(在调试器中它填充了一个代理),数据库中仍然没有条目,我不明白为什么。以下是相关课程:
public class AuditReport
{
[Key]
[ForeignKey("Audit")]
[Column("AuditReport_ID")]
public int ID { get; set; }
[Required]
public virtual Audit Audit { get; set; }
}
public class Audit
{
[Key]
public int GeneratedID { get; set; }
[Index("Audit_ID", IsUnique = true)]
public int Audit_ID { get; set; }
public virtual AuditReport AuditReport { get; set; }
}
新的AuditReport已创建的方法
public async override Task SaveChangesAsync()
{
using (var dbAccess = new DatabaseAccess())
{
var foundAudit = dbAccess.Audits.Include("AuditReport").Include("AuditReport.Stellungnahmen").SingleOrDefault(_ => _.Audit_ID == Audit.Audit_ID);
if (foundAudit != null)
{
if (foundAudit.AuditReport == null)
{
foundAudit.AuditReport = dbAccess.AuditReports.Create();
foundAudit.AuditReport.Audit = foundAudit;
}
else
foundAudit.AuditReport.Stellungnahmen.ToList().ForEach(_ => dbAccess.Entry(_).State = EntityState.Deleted);
foreach (var item in Stellungnahmen.Where(_ => _.IsChecked == true))
foundAudit.AuditReport.Stellungnahmen.Add(dbAccess.Stellungnahmen.SingleOrDefault(_ => _.KeyWord == item.KeyWord));
}
await dbAccess.SaveChangesAsync();
}
}
正如我已经说过的,我已经调试了它,一切看起来都很好。

尝试删除ID上的[Key]
,因为您已经[ForeignKey]
atrribute。
