直接上代码吧:

分页的使用：

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)
        # 分页实例化传参
        page_obj = Page(total_num=totol_num, page_num=page_num, every_page_num=9)
        # 根据分页拿到的start和end切片得到所要的数据
        data = article_list[page_obj.start:page_obj.end]
        # 调用html方法得到分页的html代码片段
        page_html = page_obj.html
        return render(request, 'home.html', {'article_list': data, 'page_html': page_html})

ps:在python脚本中调用django环境实现数据库批量添加数据操作

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

if __name__ == "__main__":
    import django
    django.setup()
    from app01 import models


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

    create()
    #
    # def delete():
    #     models.Book.objects.all().delete()

    # delete()
