Question

我一直在使用教程研究django项目，我收到了这条消息。当我点击单选框进行投票时，管理员的计数会上升，但网站会显示错误消息，而不是加载模板。看起来model.py中有错误，所以我添加了它。

views.py

from audioop import reverse
from gc import get_objects

from django.http.response import HttpResponseRedirect
from django.shortcuts import render, get_object_or_404
from django.template.context_processors import request

from polls.models import Question, Choice


# Create your views here.
def index(request):
   latest_question_list = Question.objects.all().order_by('-pub_date')[:5]
   context = {'latest_question_list': latest_question_list}
   return render(request, 'polls/index.html', context)

def detail(request, question_id):
   question = get_object_or_404(Question, pk=question_id)
   return render(request, 'polls/detail.html', { 'question' : question })

def vote(request, question_id):
question = get_object_or_404(Question, pk=question_id)
try:
    selected_choice = question.choice_set.get(pk=request.POST['choice'])
except (KeyError, Choice.DoesNotExist):
    return render(request, 'polls/detail.html', {
        'question' : question,
        'error_message' : "You didn't select a choice",
        })
else:
    selected_choice.votes += 1
    selected_choice.save()
    return HttpResponseRedirect(reverse('polls:results', args=(question.id,)))    

def results(reqeust, question_id):
    question = get_object_or_404(Question, pk=question_id)
    return render(request, 'polls/results.html', { 'question' : question })

我在eclipse中添加了从控制台获得的消息

TypeError: reverse() takes no keyword arguments
[11/Feb/2017 16:50:30] "POST /polls/3/vote/ HTTP/1.1" 500 67663

您使用以下代码行覆盖django reverse方法：

from audioop import reverse

使用django＆＃39;反过来你应该导入它：

from django.urls import reverse

如果你仍然需要音频反转，你可以使用as语法的同义词：

from audioop import reverse as audio_reverse

Django教程：/ polls / 3 / vote / reverse（）中的TypeError不带关键字参数
