FileDB | lightweight C # DLL project | File Utils library

I have developed a personal site in the local with python3.8. when I deployed the AWS ubuntu ec2 sever used the code file which deployed in the local, and when saved my blog contents, there is the following error. By the way, the site can saved well in the sever python3.6 which have been tested .

File "/home/ubuntu/.local/lib/python3.6/site-packages/whoosh/index.py", line 123, in open_dir return FileIndex(storage, schema=schema, indexname=indexname) File "/home/ubuntu/.local/lib/python3.6/site-packages/whoosh/index.py", line 421, in init TOC.read(self.storage, self.indexname, schema=self._schema) File "/home/ubuntu/.local/lib/python3.6/site-packages/whoosh/index.py", line 664, in read segments = stream.read_pickle() File "/home/ubuntu/.local/lib/python3.6/site-packages/whoosh/filedb/structfile.py", line 245, in read_pickle return load_pickle(self.file) ValueError: unsupported pickle protocol: 5

I am wondering is that a possible caused by the file in the local environment.

when I want to build my Alpine Docker I get an error when I define specific python version.

My Dockerfile:

I'm not sure if somehow the directory is wrong or there's just some kind of common mistake in my code, but I just am not able to save my uploaded file to a folder, or more specifically, the media folder as demonstrated in a lot of examples.

I'm just taking a text field and the file and saving it in the DB using Ajax, and it works too, except that whatever file I'm selecting, it's not getting saved in the media folder even if I create one manually nor is it creating one on its own either. I can get this to work without Ajax but not with it. Maybe it's something related to how I'm sending and handling data over Ajax, but I've gone through tons of forums to try and fix it but no results so far. I've double checked everything else such as the settings.py config and the libraries that I've imported, everything looks to be in order. I'm sharing the code below.

Hi everyone. I am trying to map class (FileEntity) to Hibernate using .setAnnotatedClasses() or .setPackagesToScan() methods. But I get the same error over and over again.

the main idea of this code are to loop the folder (files/), take all files from the folder (*.txt), store file name, vei_code, date to File database table. Then take that file content and store it to Content table and so on. Content and File tables are connected by foreign key. If the all store operation was successful to database, file status will be changed to 1 if not it will be 0 and all that file records will be deleted if file status will be 0. But if I want to find all files from database where status is 0 I getting empty array. Any help will be very useful. Code:

I am having trouble saving the file path to a document in my SQL database. I need to save it so I can then retrieve the file at a later stage.

So basically what the app does is that it continuously watching a specific folder for any changes. So when a file is added it detects it and then should save that file in the database. Now I am not sure what the best practice here is to save the file or just the file path?

This is the code I currently testing with:
