ASP.NET 样板实体立即提交

Question

I've started working with Entities within ASP.NET Boilerplate. Im trying to get my entities to commit to the database immediately but i cant seem to do it.

I am calling await CreateAsync(EntityDto); .

I've tried overriding the CreateAsync within my controller to include CurrentUnitOfWork.SaveChanges(); .

I have also tried to wrap the code in a unit of work.

        using (var unitOfWork = _unitOfWorkManager.Begin())
        {
            var entityDto = await CreateAsync(entityDto);
            await unitOfWork.CompleteAsync();
        }

But it never seems to commit to the database immediately.

Any help would be much apricated.

Answer 1

According to official document , all you need is to use the SaveChanges or SaveChangesAsync method of the current unit of work.

Note that if the current unit of work is transactional, all changes in the transaction are rolled back if an exception occurs. Even the saved changes.

Answer 2

ABP's Conventional Unit of Work is scoped around your Controller action and The unit of work is ambient .

You should require a new unit of work with TransactionScopeOption.RequiresNew :

using (var unitOfWork = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew))
{
    var entityDto = await CreateAsync(entityDto);
    await unitOfWork.CompleteAsync();
}

Alternatively, you can suppress the unit of work with TransactionScopeOption.Suppress :

using (var unitOfWork = _unitOfWorkManager.Begin(TransactionScopeOption.Suppress))
{
    var entityDto = await CreateAsync(entityDto);
    await unitOfWork.CompleteAsync();
}
