想法是如果我已经登入了，然后在输入login的页面时回重定向到相应用户的user下。
我目前的做法是：

if request.user.is_authenticated:
       return HttpResponseRedirect("/account/user/[相应用户名]")

urls.py

    url(r'^login',login_views, name='login'),
    url(r'^logout$',logout_views, name='logout'),
    url(r'^register', register, name='register'),
    url(r'^user/([\w]+)$',Management, name='user'),

不知道有没有比较好的内置函数或者其他的方式来解决呢？谢谢～！
views.py

def login_views(request):
    if request.user.is_authenticated:
        return HttpResponseRedirect("/account/user/das")# redirect test
    else:
        if request.method == 'POST':
            username = request.POST['username']
            password = request.POST['password']

            user_status =authenticate(username=username, password=password)
            if user_status:
                login(request, user_status)
                return JsonResponse({'status':'success','message':'登入成功'})
            else:
                if User.objects.filter(username=username):
                    return JsonResponse({'status':'error', 'message':'密码错误'})
                else:
                    return JsonResponse({'status':'error','message':'用户不存在'})
        return render(request, "sign_in.html")
