Activities of "kkmy"

Hello,

Is it possible to declare some enums to be skipped when generating proxies? That is, I do not want to create frontend proxies for them when I type "generate-proxy".

Thanks.

This works, thank you so much.

Hello,

I have a join query like this:

var result = await
(
    from car in await _carRepository.GetQueryableAsync()
    join iu in await _identityUserRepository.GetQueryableAsync() on car.CreatorId equals iu.Id
    where car.Code == "CAR-1"
    select new CarDto
    {
        Id = car.Id,
        Code = car.Code,
        CreatedAt = car.CreationTime,
        CreatedBy = iu.Name
    }
).FirstOrDefaultAsync();

However, this does not work since IdentityUserRepository does not have a GetQueryableAsync() method. What should be the approach here if I want to get the creator name in a join query?

Thanks.

Got it!

Oh I see!

Does this mean that it is better to add app.UseAbpStudioLink(); again after the next version? Or let it be removed like this?

It worked perfectly, thank you so much!

Though, I really wonder what is the corelation between AbpStudioLink and IRemoteStreamContent if it is not a secret? :) What makes it does not work?

public async Task< IRemoteStreamContent > ExportAsync(ExportDto input)
{
    var contents = new Dictionary<string, byte[]>();
    var discardedContents = new Dictionary<string, byte[]>();

    FillMuyCompressionItems(ref contents, ref discardedContents);
    FillMlCompressionItems(ref contents, ref discardedContents);
    FillAkbCompressionItems(ref contents, ref discardedContents);
    FillCkCompressionItems(ref contents, ref discardedContents);

    var zipFileName = "EXPORT.zip";

    var mainZipFileStream = new FileStream(Path.Join(Path.GetTempPath(), zipFileName), FileMode.Create, FileAccess.ReadWrite);

    using (var zipArchive = new ZipArchive(mainZipFileStream, ZipArchiveMode.Create, true))
    {
        for (var i = 0; i < contents.Count; i++)
        {
            var item = contents.ElementAt(i);
            
            using var originalFileStream = new MemoryStream(item.Value);

            var zipEntry = zipArchive.CreateEntry(item.Key, CompressionLevel.Fastest);

            await using var zipEntryStream = zipEntry.Open();

            await originalFileStream.CopyToAsync(zipEntryStream);
        }
    }

    mainZipFileStream.Seek(0, SeekOrigin.Begin);

    return new RemoteStreamContent(mainZipFileStream, zipFileName, FileTypes.Zip.ContentType);
}

public async Task< FileStreamResult > ExportAsync(ExportDto input)
{
    var contents = new Dictionary<string, byte[]>();
    var discardedContents = new Dictionary<string, byte[]>();

    FillMuyCompressionItems(ref contents, ref discardedContents);
    FillMlCompressionItems(ref contents, ref discardedContents);
    FillAkbCompressionItems(ref contents, ref discardedContents);
    FillCkCompressionItems(ref contents, ref discardedContents);

    var zipFileName = "EXPORT.zip";

    var mainZipFileStream = new FileStream(Path.Join(Path.GetTempPath(), zipFileName), FileMode.Create, FileAccess.ReadWrite);

    using (var zipArchive = new ZipArchive(mainZipFileStream, ZipArchiveMode.Create, true))
    {        
        for (var i = 0; i < contents.Count; i++)
        {
            var item = contents.ElementAt(i);
        
            var originalFileStream = new FileStream(Path.Join(Path.GetTempPath(), item.Key), FileMode.Create, FileAccess.ReadWrite);
            await originalFileStream.WriteAsync(item.Value);
            originalFileStream.Seek(0, SeekOrigin.Begin);
        
            var zipEntry = zipArchive.CreateEntry(item.Key, CompressionLevel.Fastest);

            await using(var zipEntryStream = zipEntry.Open())
            await using (originalFileStream)
            {
                await originalFileStream.CopyToAsync(zipEntryStream);
            }
        }
    }

    mainZipFileStream.Seek(0, SeekOrigin.Begin);

    return new FileStreamResult(mainZipFileStream, FileTypes.Zip.ContentType);
}

Is there an example for this? Because I have written it like the following:

public async Task< **FileStreamResult** > ExportAsync()
{
    ...
    
    return new FileStreamResult(zipFileStream, FileTypes.Zip.ContentType);
}

However, proxy generation is failed:

Hello,

I have a big zip file in the server (5GB). I am trying to send the file to the front end so that the user can download it.

return new RemoteStreamContent(zipFileStream, zipFileName, FileTypes.Zip.ContentType);

This approach works for moderate files, however gives an error for big files.

What should be the approach for big files?

Thank you.
