直接上程式碼吧:

分頁的使用：

class Home(views.View):
    def get(self, request):
        article_list = models.Article.objects.all()
        totol_num = article_list.count()
        page_num = request.GET.get("page", 1)
        # 分頁例項化傳參
        page_obj = Page(total_num=totol_num, page_num=page_num, every_page_num=9)
        # 根據分頁拿到的start和end切片得到所要的資料
        data = article_list[page_obj.start:page_obj.end]
        # 呼叫html方法得到分頁的html程式碼片段
        page_html = page_obj.html
        return render(request, 'home.html', {'article_list': data, 'page_html': page_html})

ps:在python指令碼中呼叫django環境實現資料庫批量新增資料操作

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "fenye.settings")

        obj_list = [models.Book(name = f"pyhton{i}") for i in range(160)]
        models.Book.objects.bulk_create(obj_list)

    create()
    #
