Question

我也是新的python也是Django。我知道在这个论坛上发布了同样的问题。但仍然无法弄明白。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')

它向我显示了这个错误

我在之前的帖子中尝试过很多东西，但仍然没有进展。 github repository

您实际上忘了注册您的应用，转到settings.py，您会看到一个名为INSTALLED_APPS的列表，添加您应用的名称first_app。 More info can be found here

INSTALLED_APPS = [
    #names,
    'first_app',
]

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