Usage of wrong Tenant Database #5957

kpmg created 6 years ago

Good morning,

we use multi tenancy with a host database and separate databases for several tenants. We encountered an issue when loading from the tenant database.

Some more details:

When a file is saved as binary (it could be other data types as well) with selected tenant X it cannot be loaded again in production. If we select the host, save and reload the file it works but it doesn't work on a tenant database.

The upload method is located in the C# Project <ProjectName>.Web.Core in a controller that is derived from <ProjectName>ControllerBase that is derived from AbpController.

The download method is located in the same C# project in FileController also derived from <ProjectName>ControllerBase. The download method is

public async Task<FileResult> DownloadBinaryObject(Guid id, string displayName)
	    {
		    var binary = await _binaryObjectManager.GetOrNullAsync(id);
			var file = new FileContentResult(binary.Bytes, System.Net.Mime.MediaTypeNames.Application.Octet);
		    file.FileDownloadName = displayName;
		    return file;
	    }

The upload method:

        [HttpPost]
        [AbpMvcAuthorize]
        public async Task<JsonResult> UploadFile()
        {
            try
            {
                var file = Request.Form.Files.First();
                byte[] fileBytes;
                using (var stream = file.OpenReadStream())
                {
                    fileBytes = stream.GetAllBytes();
                }

                var fileObject = new BinaryObject(null, fileBytes);
                using (CurrentUnitOfWork.SetTenantId(AbpSession.TenantId))
                {
                    fileObject.TenantId = AbpSession.TenantId;
                    await BinaryObjectManager.SaveAsync(fileObject);
                }
                return Json(new AjaxResponse(new
                {
                    id = fileObject.Id,
                    name = file.FileName,
                    contentType = file.ContentType
                }));
            }
            catch (UserFriendlyException ex)
            {
                return Json(new AjaxResponse(new ErrorInfo(ex.Message)));
            }
        }

How can we resolve this issue?
