无法导入名称 UploadDocumentForm

Question

我觉得这是一个很常见的错误，可能是因为循环导入的问题。但我在这里找不到具体的问题，结果在views.py的第3行出现了错误。

我跟着这个教程做的： https://docs.djangoproject.com/en/1.6/topics/http/file-uploads/

forms.py

from django import forms

class UploadDocumentForm(forms.Form):
file = forms.FileField(label='Select a file',
help_text='*.odt only')

views.py

from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response
from .forms import UploadDocumentForm

# Create your views here.

def upload_document(request):
if request.method == 'POST':
    form = UploadDocumentForm(request.POST, request.FILES)
    if form.is_valid():
        return HttpResponseRedirect('/success/url/')
else:
    form = UploadDocumentForm()
return render_to_response('upload.html', {'form': form})

谢谢你的帮助！

我把名字从 UploadDocumentForm 改成了 UploadFileForm，结果问题就解决了。
