forms.py

from django import forms


class UploadDocument(forms.Form):

    passport = forms.ImageField()
    id_license = forms.ImageField()

models.py

from django.conf import settings
from django.db import models


class Document(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL,
                            on_delete=models.CASCADE,)
passport = models.ImageField()
id_license = models.ImageField()

попробуйте этот код:

views.py

def upload_document(request):

if request.method == 'POST':
    form = UploadDocument(request.POST, request.FILES)
    if form.is_valid():
        instance=Document()
        instance.passport=request.FILES['passport']
        instance.id_license=request.FILES['id_license']
        instance.User=request.user
        instance.save()

        return HttpResponseRedirect('/success/url/')
else:
    form = UploadDocument()
return render(request, 'verification/verificate.html', {'form': form})
