ModelForm not submitting data

*#views.py* def check(request): if request.method == 'POST': form = UploadForm(request.POST, request.FILES) form.save() return HttpResponseRedirect("/") else: form = UploadForm() return render(request, 'upload.html', {'form': form}) def

Not able to see the dropdown field for Foreignkey ModelForm.

This is my code: *#models.py* class Subject(models.Model): departement_code=models.CharField(max_length=2,blank=False)
