导航的逻辑是判断用户是否登录，登录了显示登录看到的信息，没登录显示注册和登录。
渲染文章列表需要先注册admin,然后在admin里加入几篇文章，然后在视图函数里提取文章数据，并渲染到模板。需要注意的是显示用户头像的时候，需要在用户头像路径前加上media/
index.py和logout.py
# 首页 def index(request): article_list = models.Article.objects.all() context = { 'article_list': article_list, } return render(request, 'index.html', context=context) # 注销 def logout(request): auth.logout(request) # request.session.flush() return redirect(reverse('blog:login'))
