day25 stark组件开发之排序功能

基类新增排序条件请求函数

    order_list = []

    def get_order_list(self):
        return self.order_list or ['-id', ]

基类中页面函数逻辑变更

 def changelist_view(self, request):
        """
        列表页面
        :param request:
        :return:
        """

        queryset = self.model_class.objects.all().order_by(*order_list)
        # ########## 1. 处理分页 ##########
        all_count = queryset.count()

        query_params = request.GET.copy()
        query_params._mutable = True

        pager = Pagination(
            current_page=request.GET.get('page'),
            all_count=all_count,
            base_url=request.path_info,
            query_params=query_params,
            per_page=self.per_page_count,
        )

        data_list = queryset[pager.start:pager.end]

        # ########## 2. 处理表格 ##########
        list_display = self.get_list_display()
        # 1. 处理表格的表头
        header_list = []
        if list_display:

                header_list.append(verbose_name)
        else:

        return render(

stark组件可以自定义传排序条件
