问题描述
urls.py以及以下视图：
urlpatterns = [
path('',views.index,name='index'),path('account/',include('django.contrib.auth.urls'),name="login"),path('signup/',views.SignUp.as_view(),name='signup'),path('polls/<int:pk>/',views.DetailView.as_view(),name='detail'),path('polls/<int:pk>/results/',views.ResultsView.as_view(),name='results'),path('polls/<int:week_id>/Vote/',views.Vote,name='Vote'),]
出于某种原因，@login_required
def index(request):
return HttpResponse("Hello,there my frined")
class SignUp(CreateView):
form_class = UserCreationForm
success_url = reverse_lazy('login')
template_name = 'registration/signup.html'
class DetailView(LoginrequiredMixin,DetailView):
model = Week
template_name = "detail.html"
# Problem is here
class ResultsView(LoginrequiredMixin,DetailView):
model = Week
template_name = 'results.html'
类中的 LoginRequiedMixin 产生以下错误：
ResultsView这是我的 File "/Users/user/Projects/cafeteria/weeklydesert/urls.py",line 3,in <module>
from . import views
File "/Users/user/Projects/cafeteria/weeklydesert/views.py",line 25,in <module>
class ResultsView(LoginrequiredMixin,DetailView):
TypeError: Cannot create a consistent method resolution
order (MRO) for bases LoginrequiredMixin,DetailView
results.html去掉mixin形式<h1>Week of: {{ week.coming_monday }}</h1>
<ul>
{% for choice in week.choice_set.all %}
<li>{{ choice.desert_choice }} -- {{ choice.Votes }} Vote{{ choice.Votes|pluralize }}</li>
{% endfor %}
</ul>
<a href="{% url 'detail' week.id %}">Vote again?</a>
后代码运行正常，代码有什么问题？
