                profile = get_object_or_404(User, user=request.user)
                return render(request, 'registration/home.html', {'profile': profile})

              return HttpResponseRedirect(
                  reverse('user_profile_view', args=[request.user.username],    current_app='app'))

所以我实际上要做的是允许一个用户名出现在url中的用户登录，但是由于登录名是REDIRECT，url='/accounts/home\u page'不能像我使用重定向一样使用动态参数。但是我犯了这个错误，请问我做错了什么。 提前谢谢！！！你知道吗

#views.py    
class UserProfileView(View):
        @method_decorator(login_required)
        def get(self, request, username):
            if request.user.username == username:
                profile = get_object_or_404(UserExtended, user=request.user)
                return render(request, 'registration/home.html', {'profile': profile})
            else:
                raise Http404


    @login_required
    def home_page(request):
        return HttpResponseRedirect(
            reverse('app:user_profile_view',
                    args=[request.user.username],  current_app='app'))

所以当我跟着@ShanWang说我得到了错误时，我改变了答案：

TypeError异常值：get（）得到意外的关键字参数“username” 因为我的def get(self, request, username):是def get(self, request, user):，所以我改变了这个

if request.user.username == user: 

至

 if request.user.username == username:

成功了
