Question

我需要能够像这样对索引中的数据进行排序：

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

换句话说，我需要在URL中传递“sort_by”的值。我试图搜索文档，但我找不到任何例子。

有人能给出一个如何实现这个目标的线索吗？

我正在使用Django Haystack 2.0和SearchView（）

任何线索？

问题应该是。如何通过“points”或“date_inserted”使用以下内容将GET参数传递给订单：

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

Answer 1

覆盖haystack的get_queryset方法并将排序字段添加到索引模型中，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')
