Как реализовать загрузку файлов на сервер в Django?

# In forms.py...
from django import forms

class UploadFileForm(forms.Form):
    title = forms.CharField(max_length=50)
    file = forms.FileField()

from django.http import HttpResponseRedirect
from django.shortcuts import render
from .forms import UploadFileForm

def upload_file(request):
    if request.method == 'POST':
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/success/url/')
       return render(request, 'upload.html', {'form': form})
    else:
        form = UploadFileForm()
    return render(request, 'upload.html', {'form': form})

from django.db import models

class Article(models.Model):
    file_obj = models.FileField(upload_to='media/')

from django.shortcuts import render
from django.contrib.auth import authenticate
from django.http import HttpResponseRedirect

from .forms import ArticleForm


def Upload_file(request):
  if request.method == 'POST':
    form = ArticleForm(request.POST, request.FILES)
    if form.is_valid():
      form.save()
      return HttpResponseRedirect('/')
  else:
    form = ArticleForm()

  return render(request, 'file_upload.html', {'form': form})

from django.forms import ModelForm
from .models import Article

class ArticleForm(ModelForm):
  class Meta:
    model = Article
    fields = ['file_obj']
