3. django 后台响应部分

   from django_datatables_view.base_datatable_view import BaseDatatableView
   

   def proxyAdmin(req):

       #rows=Proxy.objects.all()[:100]

       return render_to_response('data/proxyadmin.html')

   
   

   class ProxyListJson(BaseDatatableView):

       # The model we're going to show

       model = Proxy #要分页的类

   
   

       # define the columns that will be returned

       columns = ['ip', 'description', 'score', 'logdate'] #需要显示的字段

   
   

       # define column names that will be used in sorting

       # order is important and should be same as order of columns

       # displayed by datatables. For non sortable columns use empty

       # value like ''

       order_columns = ['ip','description', 'score', 'logdate'] #排序

   
   

       # set max limit of records returned, this is used to protect our site if someone tries to attack our site

       # and make it return huge amount of data

       max_display_length = 500

   
   

       def render_column(self, row, column):

               return super(ProxyListJson, self).render_column(row, column)

   
   

       def filter_queryset(self, qs):

           # use parameters passed in GET request to filter queryset

           qs_params = None

           search = self.request.GET.get(u'sSearch', None)

           if search: #模糊搜索

               q = Q(ip__contains=search)|Q(description__contains=search)

               qs_params = qs_params | q if qs_params else q

           

               qs = qs.filter(qs_params)

   
   

           return qs

4. URLS配置

   url(r'^paging_proxy/$', ProxyListJson.as_view(), name='proxy_list_json'),
