I'm working on a personal project and I tried several approaches but none seem to work... I tried several approaches but none seem to work. I've been struggling with this for a few days now and could really use some help. I'm working with a `FileNotFoundError` when trying to upload files using Django 4.0’s FileField. The scenario arises when I attempt to save a model instance after a file has been uploaded through a form. My model is defined as follows: ```python class Document(models.Model): title = models.CharField(max_length=100) file = models.FileField(upload_to='documents/') ``` In my view, I handle the form submission like this: ```python def upload_document(request): if request.method == 'POST': form = DocumentForm(request.POST, request.FILES) if form.is_valid(): document = form.save(commit=False) document.save() return redirect('success_view') else: form = DocumentForm() return render(request, 'upload.html', {'form': form}) ``` The question occurs when I submit the form. The uploaded file is being stored temporarily, but when `document.save()` is called, I get the following behavior message: ``` FileNotFoundError: [Errno 2] No such file or directory: 'documents/your_uploaded_file.pdf' ``` I've checked my MEDIA_URL and MEDIA_ROOT settings in `settings.py`: ```python MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') ``` I ensure that the `media` directory exists and is writable by the server. I’ve also tried debugging by printing the full path of the file being saved: ```python print(document.file.path) ``` This outputs the expected path, but the behavior continues. I've also confirmed that the Django app has permission to write to the `media` directory. The file uploads correctly to the `media/documents/` folder when I check it directly after submitting the form, so I suspect that something is being mishandled during the save operation. Does anyone have insights on why this `FileNotFoundError` might be occurring despite the file being present in the upload directory? Any guidance on best practices for handling file uploads in Django would also be greatly appreciated. My development environment is Windows. What am I doing wrong? My development environment is macOS. Has anyone else encountered this? This is part of a larger application I'm building. Am I missing something obvious?
