如何用django生成博客系统出问题：Reverse for 'archives' with arguments '('', '')' not found？

Question

问题遇到的现象和发生背景

环境：python3.10+django3.2.13
问题描述：

http://localhost:8001/login/

本地登录页正常，登录后跳转到index.html出错。

问题相关代码，请勿粘贴截图

1、index.html引用的base.html相关部分：（index.html代码已经在下面的回复中做了补充）

 <div class="panel-body">
                        {% archives as date_list %}
                        <ul>
                            {% for date in date_list %}
                            <li>
                                <a href="{% url 'blog:archives' date.year date.month %}">
                                    {{ date.year }} 年 {{ date.month }}月</a>
                            </li>
                            {% empty %}
                            暂无归档！
                            {% endfor %}
                        </ul>
                    </div>

2、views.py中的

def archives(request, year, month):
   blog_list = models.Blog.objects.filter(created_time__year=year, created_time__month=month).order_by('-created_time')
   return render(request, 'blog/index.html', context={'blog_list':blog_list})

3、blog\url.py中的patterns设置：

 from django.urls import path,re_path
from . import views
app_name = 'blog'
urlpatterns = [
    path('',views.indexview.as_view(),name='index'),
    path('myindex/<int:loguserid>/',views.myindex.as_view(),name='myindex'),
    path('authorindex/<int:id>/',views.authorindex.as_view(),name='authorindex'),
    re_path('blog/(?P<pk>[0-9]+)/',views.blogdetailview.as_view(),name='detail'),
    re_path('archives/(?P<year>[0-9]{4})/(?P<month>[0-9]{1,2})/', views.archives, name='archives'),
    re_path('category/(?P<pk>[0-9]+)/', views.categoryview.as_view(), name='category'),
    re_path('tag/(?P<pk>[0-9]+)/', views.tagview.as_view(), name='tag'),
    path('search/', views.search, name='search'),
    path('login/', views.login,name='login'),
    path('registe/', views.registe,name='registe'),
    path('logout/',views.logout,name='logout'),
    path('test_ckeditor_front/',views.test_ckeditor_front),
]

运行结果及报错内容

我的解答思路和尝试过的方法

1、检查index.html及base.html；
2、检查archives函数；
3、检查urls.py设置；

我想要达到的结果

正常出现博客首页。

Answer 1

index.html代码：

{% extends 'base.html' %}
{% block main %}
{% if error_msg %}
<p>{{ error_msg }}</p>
{% endif %}
{% for blog in blog_list %}
