That line … it appears you forgot to apply `profile_path` function object. Like so  
`profile_pic = models.ImageField(upload_to=profile_path)`

try:

```auto
pip uninstall -y django
pip install django

```

Otherwise the traceback is missing out some lines that could identify the source of the error

Welcome @shaheen-coder !

Let’s take a step back and cover some basics.

What version of Django are you using?

Are you using any custom storage backends?

Is this your development environment or a production environment?

How are you running your project?

hi @KenWhitesell  
im using current version `5.0.7` on linux `4.19` kernel  
and i ain’t using any custom backend storage  
this is not a production code just a prototype.  
that error coming from django/core/files/lock `locks.py`  
i guess its sort of django framework bug

this model migrations and migrate run without any error or caution  
and i tried to add data through admin page then i getting this error

Show your code: model, view and admin.py

These items have little (if anything) to do with uploading files. Uploaded files are not stored in the database. Only the file name is stored in the database.

Almost certainly not. Yes, it’s possible. However, that’s going to be the last conclusion I’d come to - once all other reasonable possibilities have been eliminated.

What operating system are you running this on?

How are you running your project?

What uid is running your code?

What are the permissions on the `BASE_DIR / 'media'` directory?
