Hey! Very cool video! I just have a follow-up question: How do you do Multiple File Upload with Models? For example, if I want to save multiple files in the model, I know you change the IFormFile to a List in the model, but what else changes? Thanks a lot!
Ахаха чувак ты прям осветил все темы которые мне нужны для дипломной )) респект тебе и уважуха. Кстати один вопрос, я четкого ответа нигде не получил, как лучше хранить музыкальные файлы формата mp3 в базе данных как битовый массив или в файловой системе ?
Спасибо, и удачки на задаче. Мп3 от других файлов сильно не отличаются. Если сохронять как файл то придётся стримить как страничка загрузится. Если как бити то их можна в base64 прям в src кидать или тоже стримить но больше памяти и ресурсов занимать в DB будет. Тоже blob дешевле DB. Я предпочитаю сохронять файли на диск. Если будешь сохронять в DB то делай для них отдельную таблицу id, bytes.
I wanna use IFormFile or FormFile method in asp.net mvc too. Can we use it? HttpPostedFileBase is easy but I wanna use only one class for upload images and FormFile seems cool.
Watched the 7 first minutes to get started. Now I has a system that takes the uploaded image. Computes its SHA256 hash and use it as a filename. Writes the copy of the file into a subfolder. Works fairly well, but I have 2 issues. Folder should exist prior to writing file. Kinda makes sense from a technical PoV but on the other hand it would be nice if the proper folder is created if needs be. Actually this is Path.Combine that throws the exception because the path which is combined does not exist. So I shall combine the path on its own line in a try/catch and create the folder if needed. Second issue is I wonder how I should refactor this so that it is clean and reusable amongst my webapp. Creating a service ? I'll probably watch the rest of the video later. Thanks for the help.
Sorry for the late response - you should store files in cloud storage really, having a service for that makes the most sense. I have some videos in my Tricking Library series on that, the project source code is freely available as well.
so something's up with the updated versions from something. Using vs 2022 and even just the stuff form the first 4 mins didnt work... could you help a little? or update the repo? (I think-)the main error I'm getting is in startup.cs, the " app.UseMvcWithDefaultRoute(); ", with the error message being: " System.InvalidOperationException: "Endpoint Routing does not support 'IApplicationBuilder.UseMvc(...)'. To use 'IApplicationBuilder.UseMvc' set 'MvcOptions.EnableEndpointRouting = false' inside 'ConfigureServices(...)." " and idk how I'm supposed to disable that
Great tutorial! I have a question regarding the path for axios.post("/Home/SingleFile", formData). Can I ask you how did the path become "/Home/SingleFile"? Is it "/`controllerName`/`IActionResult name`"? Somehow the path is not working, and console throws an error of 400 :(
Yes the way you think about the path is correct. 400 means there is an error, if you don't hit the back end at all and you are using dotnet core 3 you'll have to submit an intiforgery token too.
@@yoonvak Here's the solution to the issue. stackoverflow.com/a/47633056/5784635 Use @Html.AntiForgeryToken() to generate the anti forgery token and then add it to your request as a __RequestVerificationToken on the request
@@RawCoding Thank you so much! i have a extra question regarding the solution, should I create a new class with the "HttpContextExtensions"? Or can I just add that in the controller where I have the "singleFile" function in it?
Thank you very much for the nice video, I've couple question what is the maximum size for the upload? if you want to upload 10gb files what would be the best approach?
Thank you! Maximum size of upload for IIS is 28MB, you can change this. Please read the docs docs.microsoft.com/en-us/aspnet/core/mvc/models/file-uploads?view=aspnetcore-3.0#troubleshooting
@@RawCoding Files bigger than 1GB normally require MultiReader Filestreaming instead of IFormFile, otherwise it will just crash with Error 404 due to memory restrictions. docs.microsoft.com/de-de/aspnet/core/mvc/models/file-uploads?view=aspnetcore-5.0#upload-large-files-with-streaming Great tutorials anyways!
Thanks for sharing this video. This is a lot clearer video tutorial for uploading a file in ASP.NET core than other video tutorial. Nice and clean! Thanks again! By the way, what if i'll be uploading a doc and pdf file? And how to show the uploaded files in the view page? I hope you could help me out on this. Thanks again!
Hey there just to clarify you want to know how to display the contents of these files on the page? Or do you mean list the files that you have uploaded and perhaps download them?
@@RawCoding Hi there! Sorry can't make replies the past days. Yes, I also wanted to download it by users if possible. So the files can be displayed in list and can be downloaded also if possible. Many thanks raw coding 😊
@@RawCoding I need this because currently I'm making a project in our school where they can upload documents in the database and they can also download it when they need. It's more of a document manager where they can sort there documents or search it rather than having it to folders and many subfolders. Sorry if I make confusions but hoping that you could help me. I'm really stuck on this part. Thanks again.
Sorry, I am having some problems on making this work. The form from the view doesn't reach the parameter in the SingleFile action. It says that it's an unused parameter even though it has the same name
@@RawCoding I tried and it comes with "HTTP Error 500.31 - ANCM Failed to Find Native Dependencies" must be because of the version Edit: Managed to make it work! Thank youu!!!
@@RawCoding I agree. I have been looking and have come up short. The best workaround I have found so far is to use get('key') or get('key') from the console. I have also incorporated a check in my JS function call to ensure the value is there. I'm doing all of this because I am running into an issue with .netcore 3 is closing the connection. I am using the JS fetch API. Any idea's on what closes connections or how to debug the issue prior to reaching the API controller?
Hello ppl! One doubt, if I am to implement this functionality in my online shop "create product" admin section, I would have to wrap the "add new product" section into a form then do a post with all the product details from name, description etc to imageFile right? I mean its the best option given the shop implementation isn't it? and then do the appropiate ammenments into the CreateProduct controller action as you are doing in this video. Then in the index page where the products are being displayed, just select the imageFile prop in product.ImageFile for example in order to display that product image. Am I going in the right direction?
No, you’ll need to add a setting in Progam.cs if you host on IIS you’ll need a setting in your webconfig, if Linux you’ll need to add a setting to your nginx config
@@RawCoding Brother, 1. multiple attachment exists (Hints: foreach (var file in files) ) 2. This is a part of a code. save changes calls latter. My problem: here all file is being uploaded but only one row inserted in database. Please try to provide me a solution. It will helps me a lot.

Notice that in an api web project, the data comes to me in null, I can't upload the image: /
What code are you using to upload the image?
Default model binding is slightly different for API controllers if you added the [ApiControllerAttribute].

You have a single attachment reference, 1 object, Uno variable . You never create more than 1 attachment

I’m on phone. Put the attachment inside your loop. Create a new object for each file
