用参数‘()和关键字参数’{‘请求’：<WSGIRequest: POST‘/search/’>}反转。0已尝试的模式：[]

Question

我有个问题：

为什么会有这个错误？用参数“()”和关键字参数“{‘请求’：}”反向查找“index”。0已尝试的模式：[]

views.py
def index(request):
...
def book(request, cate):
...
def search(request):
    if request.method == 'POST':
        searchbooktitle = request.POST.get('search')
        print(searchbooktitle)
        try:
            searchbook = Book.objects.filter(title__contains=searchbooktitle)
            return redirect(book, request=request, cate=searchbook.pk)
        except:
            print(request)
            return redirect(index, request=request)
    return redirect(index, request=request)

urls.py
urlpatterns = [
    url(r'^index/$', views.index, name='index'),
    url(r'^book/(?P<cate>[a-zA-Z]+)/$', views.book, name='book'),
    url(r'^chapter/(?P<pk>[0-9]+)/$', views.chapter, name='chapter'),
    url(r'^content/(?P<bookpk>[0-9]+)/(?P<chapterpk>[0-9]+)/$', views.content, name='content'),
    url(r'^search/$', views.search, name='search'),
]


Traceback Switch to copy-and-paste view

您不应该在重定向中传递请求。将return redirect(index, request=request)更改为return redirect('/index/')

请参考https://docs.djangoproject.com/en/1.11/topics/http/shortcuts/#django.shortcuts.redirect了解有关重定向的更多信息。
