我跟着教程学习Django，之前的内容都运行正常，但现在遇到一个问题：我在views.py里尝试用get_context_data()方法给类视图添加新的上下文键值对，但这些数据无法在HTML模板中渲染出来。以下是我目前的代码和情况：

views.py 代码

from django.shortcuts import render
from django.views.generic import TemplateView   

# Create your views here.
def home_page_view(request):
    context = {    
        "inventory_list": ["Widget 1", "Widget 2", "Widget 3"],
        "greeting": "THanK yOu foR viSitiNG!",
    }
    return render(request, "home.html", context)

class AboutPageView(TemplateView):   
    template_name = "about.html"

def get_context_data(self, **kwargs):    # new
    context = super().get_context_data(**kwargs)
    context["contact_address"] = "123 Jones Street"
    context["phone_number"] = "01234 678910"
    return context

about.html 模板代码

<h1>Company About Page</h1>
<p>The company address is {{contact_address}}.</p>
<p>The company phone number is {{phone_number}}.</p>

urls.py 代码

from django.urls import path
from .views import home_page_view, AboutPageView  

urlpatterns = [
    path("about/", AboutPageView.as_view()),   
    path("", home_page_view)
]

当我启动开发服务器访问about页面时，模板中的{{contact_address}}和{{phone_number}}并没有被替换成我设置的具体值，页面输出效果如下：
