Django将表单上传到S3 img和表单验证

我对Django和Python都相当陌生。这是我第一次用django使用表格和上传文件。我可以上传并保存到数据库以正常工作，但无法验证电子邮件或检查用户是否选择了要上传的文件。我花了很多时间阅读文档，试图弄清楚这一点。谢谢！Django将表单上传到S3 img和表单验证

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.') 
    user_email = forms.EmailField(required=True,help_text='Please type a valid e-mail address.') 
    user_twittername = forms.CharField() 
    user_website = forms.URLField(max_length=128,) 
    user_desc = forms.CharField(required=True,widget=forms.Textarea,label='Description',)

template.html

<div id="stylized" class="myform"> 
    <form action="." method="post" enctype="multipart/form-data" width="450px"> 
     <h1>Photo Submission</h1> 
     {% for field in form %}

     {% endfor %} 
     <label><span>Click here</span></label>  
    <input type="submit" class="greenbutton" value="Submit your Photo" />

放弃这个现在后。在本地上传，并将在未来提出建议。 – citadelgrad 2010-03-27 01:33:07
