Django：CSRF令牌丢失或不正确

Question

错误位于位置http://127.0.0.1:8000/fileupload/form.py

我有Django的1.3版。我尝试按照其他人的问题指定localhost：8000，但这对我不起作用。我正在尝试使用文件上传表单，但是收到一个错误，form.py没有CSRF令牌。

form.py：

class UploadFileForm(forms.Form):

    title = forms.CharField(max_length=50)
    file  = forms.FileField()

views.py：

def upload_file(request):

    c = {}
    c.update(csrf(request))

    if (not request.user.is_authenticated()) or (request.user == None):
      return HttpResponseRedirect("/?error=11")


    if request.method == 'POST':
      form = c['UploadFileForm'] = UploadFileForm(request.POST, request.FILES,  c, context_instance=RequestContext(request))

      if c['UploadFileForm'].is_valid():
        handle_uploaded_file(request.FILES['file'])
        return HttpResponseRedirect('/success/url/')

    else:
        form = c['UploadFileForm'] = UploadFileForm()
    return render_to_response('fileupload/upload.html', {'form': c['UploadFileForm']})

upload.html：

{% block main_content %}


  <form action="fileupload/form.py" enctype="multipart/form-data" method="POST">
    {% csrf_token %}
    <table>

      <tr><td>Title:</td><td><input type="text" name="title" /></td></tr>
      <tr><td>File:</td><td><input type="file" name="file" /></td></tr>
    </table>
      <input type="submit" value="Submit" class = "float_right button_input" />

  </form>

{% endblock main_content %}

我很沮丧，请告诉我一些尝试的方法。谢谢

您需要传递RequestContextrender_to_response作为csrf_token

为此：（ views.py ）

from django.template import RequestContext

...

return render_to_response('fileupload/upload.html', {'form': c['UploadFileForm']},  RequestContext(request))
# Added RequestContext

这会将csrf的令牌传递到模板。
