Django Haystack在内容类型对象上引发属性错误

时间：2014-05-26 17:14:25

标签： python django django-haystack whoosh

这有点奇怪，因为Xapian中没有出现错误。

我在django-haystack==1.2.7和Whoosh==2.4.1。它能够构建索引，但是当我运行搜索时，它的说法是

AttributeError at /search
'NoneType' object has no attribute 'concrete_model'

确切的回溯就在这里

我一直在使用django.contrib.comments（因为django框架版本是1.4.2），异常是在

引发的 
{% get_comment_count for entry as comment_count %}

这有点奇怪，因为它不是搜索的一部分！

搜索视图端点返回

SearchView().__call__(request)

我无法弄清楚至少有什么不对，最近发生了什么。 任何新的领导都会非常有帮助
