Python “文档”对象不是可下标的Django

我在上传excel文件并保存该文件时遇到此错误

My model.py文件

class Document(models.Model):
    docfile = models.FileField(upload_to='documents/%Y/%m/%d')

在视图中，我正在将该文件保存到特定位置 views.py文件是

def excel(request):
    print "you in main"
    if request.method == 'POST':
        print "you in post"
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            newdoc = Document(docfile = request.FILES['docfile'])
            path = os.path.join(settings.MEDIA_ROOT, newdoc)
            print path
            print "you in"
            newdoc.save()

            wb = xlrd.open_workbook(path)
            sh = wb.sheet_by_index(0)
            c = 1
            while c < len(sh.col(0)):
                first = sh.col_values(0)[c]
                second = sh.col_values(1)[c]
                c=c+1
            return HttpResponseRedirect(reverse('upload.views.excel'))
    else:
        form = UploadFileForm() # A empty, unbound form
    documents = Document.objects.all()
    return render_to_response('property/list.html',{'documents': documents, 'form': form},context_instance=RequestContext(request))

请帮我解决这个问题

您的问题在这里：

path = os.path.join(settings.MEDIA_ROOT, newdoc)

^newdoc是一个模型实例，您不希望模型本身成为您路径的一部分-您希望上传的文件路径在那里，因此：

path = os.path.join(settings.MEDIA_ROOT, newdoc.docfile)

---

我得到的错误是'FieldFile'对象没有属性'filename'，所以只需要newdoc.docfile，或者如果有合适的属性print dirnewdoc.docfile，则打印内容docfile

path = os.path.join(settings.MEDIA_ROOT, newdoc)

path = os.path.join(settings.MEDIA_ROOT, newdoc.docfile)
