NHibernate SaveOrUpdate存储库不会更新，而是保存数据

Question

我有两个控制器为SaveOrUpdate调用相同的CommandHandler。其中一个Controller是普通的MVC 控制器，而另一个是WebAPI ApiController 。两者在Save中工作正常但在更新时它只适用于普通的MVC控制器，不适用于 ApiController 。

我检查了来自ApiController的ViewModel，其填充与普通Controller完全相同。我还对数据库进行了一些跟踪，似乎它没有运行Update Query，只是忽略了提交的数据。

这是代码

public class SaveOrUpdateRequestNameChangeCommandHandler : ICommandHandler<SaveOrUpdateRequestNameChangeCommand>
{
    private readonly INHibernateRepository<RequestStatus> requestStatusRepository;

    private readonly INHibernateRepository<RequestNameChange> requestNameChangeRepository;

    public SaveOrUpdateRequestNameChangeCommandHandler(
        INHibernateRepository<RequestStatus> requestStatusRepository,
        INHibernateRepository<RequestNameChange> requestNameChangeRepository)
    {
        this.requestStatusRepository = requestStatusRepository;
        this.requestNameChangeRepository = requestNameChangeRepository;
    }

    public void Handle(SaveOrUpdateRequestNameChangeCommand command)
    {           
        var requestNameChange = command.RequestNameChangeId.HasValue
            ? requestNameChangeRepository.Get(command.RequestNameChangeId.Value)
            : new RequestNameChange();

        requestNameChange.Username = command.Username;
        requestNameChange.OriginalFirstName = command.OriginalFirstName;
        requestNameChange.OriginalLastName = command.OriginalLastName;
        requestNameChange.NewFirstName = command.NewFirstName;
        requestNameChange.NewLastName = command.NewLastName;
        requestNameChange.EffectiveDate = command.EffectiveDate;
        requestNameChange.NewEmailAddress = command.NewEmailAddress;
        requestNameChange.IsRetailUser = command.IsRetailUser;
        requestNameChange.SpecialRequirements = command.SpecialRequirements;
        requestNameChange.Notes = command.Notes;
        requestNameChange.ServiceDeskId = command.ServiceDeskId;
        requestNameChange.ServiceDeskUrl = command.ServiceDeskUrl;
        if (command.RequestStatusId != null)
            requestNameChange.RequestStatus = requestStatusRepository.Get(command.RequestStatusId.Value);
        requestNameChange.DateCreated = command.DateCreated;
        requestNameChange.CreatedBy = command.CreatedBy;

        requestNameChangeRepository.SaveOrUpdate(requestNameChange);

        command.RequestNameChangeId = requestNameChange.Id;
    }
}

我不确定我做错了什么，这让我在过去的几天里发疯了。

以下是来自普通控制器

的值

这是来自 ApiController

的值

正如你所看到的，除了CreatedBy之外它们完全相同（不要担心这个，我确实在我的测试中使这个相同）但是它们来自ApiController的一个不会更新值。

非常感谢任何帮助。

以下是控制器

的代码

[HttpPost]
[Transaction]
public ActionResult SaveOrUpdate(RequestNameChangesViewModel viewModel, [DataSourceRequest]DataSourceRequest request)
{
    if (ModelState.IsValid)
    {
        var command = new SaveOrUpdateRequestNameChangeCommand(
                        viewModel.RequestNameChangeId,
                        viewModel.Username,
                        viewModel.OriginalFirstName,
                        viewModel.OriginalLastName,
                        viewModel.NewFirstName,
                        viewModel.NewLastName,
                        viewModel.EffectiveDate,
                        viewModel.NewEmailAddress,
                        viewModel.IsRetailUser,
                        viewModel.SpecialRequirements,
                        viewModel.Notes,
                        viewModel.ServiceDeskId,
                        viewModel.ServiceDeskUrl,
                        viewModel.RequestStatusId,
                        viewModel.DateCreated,
                        viewModel.CreatedBy
                        );

        if (ModelState.IsValid)
        {
            commandProcessor.Process(command);
            viewModel.RequestNameChangeId = command.RequestNameChangeId;
        }
    }

    var result = new[] { viewModel }.ToDataSourceResult(request, ModelState);

    return Json(result);
}       

这是ApiController的代码

// POST Api/<controller>
[Transaction]
public void Post(RequestNameChangesViewModel viewModel)
{
    if (ModelState.IsValid)
    {
        var command = new SaveOrUpdateRequestNameChangeCommand(
            viewModel.RequestNameChangeId,
            viewModel.Username,
            viewModel.OriginalFirstName,
            viewModel.OriginalLastName,
            viewModel.NewFirstName,
            viewModel.NewLastName,
            viewModel.EffectiveDate,
            viewModel.NewEmailAddress,
            viewModel.IsRetailUser,
            viewModel.SpecialRequirements,
            viewModel.Notes,
            viewModel.ServiceDeskId,
            viewModel.ServiceDeskUrl,
            viewModel.RequestNameChangeId,
            viewModel.DateCreated,
            viewModel.CreatedBy
            );

        if (ModelState.IsValid)
        {
            commandProcessor.Process(command);
            viewModel.RequestNameChangeId = command.RequestNameChangeId;
        }
    }
}

// PUT Api/<controller>/5
[Transaction]
public void Put(int id, RequestNameChangesViewModel viewModel)
{
    if (ModelState.IsValid)
    {
        var command = new SaveOrUpdateRequestNameChangeCommand(
            viewModel.RequestNameChangeId,
            viewModel.Username,
            viewModel.OriginalFirstName,
            viewModel.OriginalLastName,
            viewModel.NewFirstName,
            viewModel.NewLastName,
            viewModel.EffectiveDate,
            viewModel.NewEmailAddress,
            viewModel.IsRetailUser,
            viewModel.SpecialRequirements,
            viewModel.Notes,
            viewModel.ServiceDeskId,
            viewModel.ServiceDeskUrl,
            viewModel.RequestNameChangeId,
            viewModel.DateCreated,
            viewModel.CreatedBy
            );

        if (ModelState.IsValid)
        {
            commandProcessor.Process(command);
            viewModel.RequestNameChangeId = command.RequestNameChangeId;
        }
    }
}

在我看来，在API方法中没有使用id字段，不应该将它设置为命令对象吗？

// PUT Api/<controller>/5
[Transaction]
public void Put(int id, RequestNameChangesViewModel viewModel)
{
    if (ModelState.IsValid)
    {
        var command = new SaveOrUpdateRequestNameChangeCommand(
            id,
            viewModel.Username,
            viewModel.OriginalFirstName,
            viewModel.OriginalLastName,
            viewModel.NewFirstName,
            viewModel.NewLastName,
            viewModel.EffectiveDate,
            viewModel.NewEmailAddress,
            viewModel.IsRetailUser,
            viewModel.SpecialRequirements,
            viewModel.Notes,
            viewModel.ServiceDeskId,
            viewModel.ServiceDeskUrl,
            viewModel.RequestNameChangeId,
            viewModel.DateCreated,
            viewModel.CreatedBy
            );

        if (ModelState.IsValid)
        {
            commandProcessor.Process(command);
            viewModel.RequestNameChangeId = command.RequestNameChangeId;
        }
    }
}

Answer 2

之后

requestNameChangeRepository.SaveOrUpdate(requestNameChange);

只需提交更改即可添加此代码。

requestNameChangeRepository.DbContext.CommitChanges();
