Question

我正在使用django1.8和haystack 2.4以及solr 4.10。不知怎的，order_by没有按预期工作，请看下面的代码，

>>> sqs = SearchQuerySet()
>>> sqs = sqs.using('entry').filter(status=0)
>>> for b in sqs.filter(content="see").order_by('title'): print b.title

Answer 1

最近我对haystack order_by的标题也有同样的问题。我使用python lambda函数对对象列表进行排序。

使用标题升序：

sqs = sqs.using('entry').filter(status=0)
sorted_list = sorted([s.object for s in sqs], key=lambda x: x.title, reverse=False)

降序：

sqs = sqs.using('entry').filter(status=0)
    rev_sorted_list = sorted([s.object for s in sqs], key=lambda x: x.title, reverse=True)

sqs.order_by适用于整数字段。

haystack order_by not not proper
