I use the Helhum upload example to upload pdf files. The first upload works fine. But when I try to edit the record and replace the previously uploaded file, I get the following error: "The identity property "xxx.pdf" is no UID. I am using TYPO3 9.
How can I fix it?

When I am trying to upload image using graph EndPoint then images are getting corrupted.

Anything I am missing here?
SharePoint Message When trying to view uploaded (through above code)image. Tried without encoding as well. Even file name is not encoded then also its same behavior.
Note - This issue is with only images. Other files like PDF, CSV are working fine.
Changing form-data to binary solved my problem.
I have Cloudinary API added to my Rails 6 application. Photo extensions and video extension uploads work great. .zip extensions do not. I've run into two errors while trying to upload a zip file.
CloudinaryException (Unsupported ZIP file):
ActiveModel::UnknownAttributeError (unknown attribute 'type' for Photo.)
In my controller for uploading the zip file, I tried to upload a zip file in different ways.
First I tried
#value = Cloudinary::Uploader.upload(params[:downloadable],
folder: "game_zip", resource_type: :raw)
Second I tried
#value = Cloudinary::Uploader.upload(params[:downloadable])
Third I tried
#value = Cloudinary::Uploader.upload(params[:downloadable],
:resource_type => :auto)
I read in Cloudinary documents that using raw file types is how you can upload zip files, I tried what they recommended, but it's not working. Is there a solution or option that I need to add?
Cloudinary recently updated its security policies, and now restricts both pdf and archive file types on new Free accounts.
This can be bypassed by contacting Cloudinary's support, or by upgrading your account.
I want to attach pdf files to my application, this pdf file is stored in "Pages" application of iOS, when I try to attach this file, I am easily able to access the pdf file URL, but when I try to send the pdf to server it gives me the following error :
The file “12312331.pdf” couldn’t be opened because you don’t have permission to view it.
I used UIDocumentBrowserViewController with the desired delegate methods to get the local files,
I have already set the required keys in "Info.plist".
I am working on a rails engine that uploads a excel file, validates it and if there is no error than it will save it to database.
Now when ever a user mounts the engine and than go to the route provided by engine. He will have a form to upload the excel file. There are two buttons on page, i.e, upload and validate.
Once a user choose the file and when he click on upload i want that file only gets uploaded and don't get saved in db. Once i get the message the file is uploaded successfully, than i will validate the file. If it is a valid excel file with valid data than it will be saved into db. Now i am not getting how to go about it. I have seen this Railscasts video on uploading csv and excel file but here he is performing validation and save operation with import action but i want validation and save operation when user clicks on validate action. This Questions seems similar to my problem but i am not getting how do i access that uploaded file. I don't want that file to be saved in database. I mean when a user click on upload button that file gets only uploaded not saved. Than i will validate that file and save it's content to db.
This may seem very easy and simple questions for some experts but i am very new to rails and i am not sure how to go about it.
Someone please help me with a sample code, so that i can understand the workflow. Also note that both upload and validate actions are on same page. So when a file gets uploaded it needs to be stored somewhere temporarily, this is the first problem i am facing. I can do all the task if someone can tell me workflow with a sample code about uploading excel file. I am only having problem here that as both upload and validate action are on same page, so after upload request it needs to be on that page so that i can validate that file.
Any help would be appreciated, I am very beginner at rails and really confused here.
Two options:
Write code to upload the file and save to DB with a validated column set to false. Then the 'validate' button will locate the unvalidated file, validate it and set validated to true. You could have a periodic job deleting unvalidated files of a certain age. If you do this, use a helper gem like Paperclip.
Forego file upload frameworks and just manually save uploaded files to Tempfile.new 'spreadsheet'. This guide takes you through how to do that. Save that filename to session and use it to validate at a later point. When you're finally ready to persist to DB, again, consider using a helper gem.
I am starting up with rails and was going thru the sharebox-tutorial.
Now is it possible with paperclip to first preview the uploaded files and then choose the download link, rather than the file directly being downloaded when link is clicked, as in the tutorial and elsewhere in the internet.
Also, what will be the method to generate a share link unique to every friend email.
While researching, i also found out that files should be uploaded in some other folder but public.
how is it different from storing the files in public folder with the url hashed. the hash url is still accessible when user is logged out.
UPDATE
the preview i am referring to should be after uploading.
