Django將表單上傳到S3 img和表單驗證

我對Django和Python都相當陌生。這是我第一次用django使用表格和上傳文件。我可以上傳並保存到數據庫以正常工作，但無法驗證電子郵件或檢查用戶是否選擇了要上傳的文件。我花了很多時間閱讀文檔，試圖弄清楚這一點。謝謝！Django將表單上傳到S3 img和表單驗證

views.py

def submit_photo(request): 
    if request.method == 'POST': 
     def store_in_s3(filename, content): 
      conn = S3Connection(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY) 
      bucket = conn.create_bucket(AWS_STORAGE_BUCKET_NAME) 
      mime = mimetypes.guess_type(filename)[0] 
      k = Key(bucket) 
      k.key = filename 
      k.set_metadata("Content-Type", mime) 
      k.set_contents_from_file(content) 
      k.set_acl('public-read') 

     if imghdr.what(request.FILES['image_url']): 
      qw = request.FILES['image_url'] 
      filename = qw.name 
      image = filename 
      content = qw.file 
      url = "http://bpd-public.s3.amazonaws.com/" + image 

      data = {image_url : url, user_email : request.POST['user_email'], user_twittername : request.POST['user_twittername'], user_website : request.POST['user_website'], user_desc : request.POST['user_desc']} 
      s = BeerPhotos(data) 
      if s.is_valid(): 
       #import pdb; pdb.set_trace() 
       s.save() 
       store_in_s3(filename, content)  
       return HttpResponseRedirect(reverse('photos.views.thanks')) 
      return s.errors 
     else:   
      return errors 

    else: 
     form = BeerPhotoForm() 

    return render_to_response('photos/submit_photos.html', locals(),context_instance=RequestContext(request)

forms.py

class BeerPhotoForm(forms.Form): 
    image_url = forms.ImageField(widget=forms.FileInput, required=True,label='Beer',help_text='Select a image of no more than 2MB.')
