django.core.exceptions.AppRegistryNotReady：应用程序尚未加载。当我导入模型时

Question

我是新蟒蛇也是Django。我知道这个论坛上发布了同样的问题。但是，仍然想不通。 创建了一个模型，需要导入我的 views.py 文件，以便我可以渲染我的数据。

这是我的 views.py

from  first_app.models import Topic, webpage, AccessRecord 
from django.shortcuts import render
from django.http import HttpResponse
# from django.apps import AppConfig
# Create your views here.
def index(request): 
webpage_list = AccessRecord.objects.order_by('date')
date_dict = {'acess_records': webpage_list}
return render(request, 'first_app/index.html')

它向我展示了这个错误

我尝试了上一篇文章中的许多东西，但仍然没有进展。 GitHub 存储库

>你居然忘了注册你的应用，去settings.py，你会看到一个名为INSTALLED_APPS的列表，添加你的应用名称first_app。 更多信息可以在这里找到

INSTALLED_APPS = [
#names,
'first_app',
]
