Django-Haystack - 如何使用獲取參數進行排序？

Question

我需要能夠將數據從這樣的指標進行排序：

http://mywebapp.com/search/?q=something&sort_by=points-desc 

換句話說，我需要在URL中傳遞「sort_by」的價值。我試圖搜索文檔，但我找不到任何示例。

有人可以提供一個關於如何實現這一目標的線索嗎？

我使用Django的草垛2.0和搜索查看（）

任何線索？

的問題應該是。我怎樣才能通過GET參數由「點」或「date_inserted」使用這樣的命令：乾草堆

覆蓋get_queryset方法並添加您的排序字段，索引模式，例如：

class LinkListView(ListView): 
    context_object_name = 「link」 

    def get_queryset(self): 
     sort = self.request.GET.get(‘sort_by’) 
     if sort: 
      return Link.published.filter().order_by('{0}'.format(sort)) 
     else: 
      return Link.published.filter().order_by('-date_inserted')
