python - "The view didn' t 返回一个 HttpResponse 对象”

Question

这是我遇到的错误: View extraio.file_uploader.views.Upload_File 没有返回 HttpResponse 对象。

谁能看出我在这里做错了什么？我似乎无法弄清楚为什么我会收到该异常，因为我正在返回 HttpResponseRedirect。

from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response
from models import Files
from forms import Upload_File_Form

def Upload_File(request):
    if request.method == 'POST':
        form = Upload_File_Form(request.POST, request.FILES)
        if form.is_valid():
            for f in request.FILES.get_list('file'):
                f.save()
                orgfilename = Files(orgname=f.name)
                orgfilename.save()
            return HttpResponseRedirect('success.html')
        else:
            form = Upload_File_Form()
            return render_to_response('upload.html', {'form': form})

您仅在 POST 请求时返回您的 HttpResponse 对象。像这样重写你的 View

def Upload_File(request):
    form = Upload_File_Form(request.POST or None,
                            request.FILES or None)
    if request.method == 'POST':
        if form.is_valid():
            for f in request.FILES.getlist('file'):
                f.save()
                orgfilename = Files(orgname=f.name)
                orgfilename.save()
            return HttpResponseRedirect('success.html')
   return render_to_response('upload.html', {'form': form},
                             context_instance=RequestContext(request))

编辑:顺便说一句，您忘记在render_to_response 中设置context_instance您也可以使用 render 代替

render(request, 'upload.html', {'form': form})

request.FILES.get_list('file') 应该是 request.FILES.getlist('file')
