重定向时的 NoReverseMatch 错误

Question

网址

url(r'^add/$', 'advice.views.add_new_advice'),
url(r'^$', 'advice.views.index'),
url(r'^(?P<advice_id>\d+)/$', 'advice.views.detail'),

视图

def add_new_advice(request):
    if request.method == "POST":
        form = AdviceForm(request.POST)
        if form.is_valid():
            new_advice = form.cleaned_data["advice"]
            advice = Advice(advice = new_advice)
            advice.save()
            return redirect('detail', advice_id = advice.id)
    else:
        form = AdviceForm()

    return render_to_response("create.html", {"form" : form},
                              context_instance=RequestContext(request))

def detail(request, advice_id):
    try:
        advice = Advice.objects.get(pk = advice_id)
    except Advice.DoesNotExist:
        return redirect('index')

    return render_to_response("detail.html", {"advice" : advice})

def index(request):
    advices = Advice.objects.all()
    advice = choice(advices)

    return redirect('detail', advice_id = advice.id)

嘿，我遇到一个问题。每次我想跳转到详细信息的功能时，都会出现 NoReverseMatch 的错误，显示在 / 这个地方。请帮帮我。

NoReverseMatch at /
Reverse for 'detail' with arguments '()' and keyword arguments '{'advice_id': 7}' not found.

你没有调用任何叫做 "detail" 的东西，所以它找不到。你可以在你的 urls.py 文件里添加这个名字，或者使用函数的完整路径，或者直接传递函数本身，而不是用字符串。
