Django的文件上传

Question

这里是欣赏代码：

def index(request): 
    if request.method == 'POST': 
     a=request.POST 
#  logging.debug(a["title"]) 
#  logging.debug(a["file"]) 
     #form = UploadFileForm() 
     form = UploadFileForm(request.POST, request.FILES) 
     #handle_uploaded_file(request.FILES['file']) 
     if form.is_valid(): 
      handle_uploaded_file(request.FILES['file']) 
      return HttpResponseRedirect('/') 
    else: 
     form = UploadFileForm() 
    return render('upload.html', {'form': form}) 


def handle_uploaded_file(file): 
# logging.debug("upload_here") 
    if file: 
     destination = open('/tmp/'+file.name, 'wb+') 
     #destination = open('/tmp', 'wb+') 
     for chunk in file.chunks(): 
      destination.write(chunk) 
     destination.close() 

这里是机型代码：

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

这里是upload.html代码：

{% block upload %} 

<form enctype="multipart/form-data" method="post" action="/upload/"> 

    {% csrf_token %} 
    <table> 
     <tr><td> 
      <input type="file" value="title" name="title" id="title" /><br /> 
      <input type="submit" value="Submit" id="Save"/> 
     </td></tr> 
    </table> 
</form> 
{% endblock %} 

选择文件后，按提交按钮，出现错误：

AttributeError的在/上传/

'WSGIRequest' 对象有没有属性 '块'

请求方法：POST 请求URL：http://www.mywebsite.com/upload/ Django的版本：1.3 异常类型：AttributeError的 异常值：

'WSGIRequest'对象没有属性'块'

异常位置：/usr/src/wpcms/views.py在handle_uploaded_file中，第63行

任何想法我在这里做错了吗？我忘了设置线吗？或者，一条进口线？ 谢谢。

Answer 1

有多种问题。这是一个可行的固定版本：

1）更改模板的实际形式：

<form enctype="multipart/form-data" method="post" action="/upload/"> 
    {% csrf_token %} 
    <table> 
     {{form.as_table}} 
    </table> 
    <input type="submit" value="Submit" id="Save"/> 
</form> 

2）更新您的形式在FileField或删除不必要的类型：

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

3）更新您的视图添加CSRF：

def index(request): 
    if request.method == 'POST': 
     a=request.POST 
     form = UploadFileForm(request.POST, request.FILES) 
     if form.is_valid(): 
      handle_uploaded_file(request.FILES['file']) 
      return HttpResponseRedirect('/') 
    else: 
     form = UploadFileForm() 

    c = {'form': form} 
    c.update(csrf(request)) 
    return render_to_response('upload.html', c) 

希望这有助于！
