Question

我正在使用django 1.7.7和django-haystack 2.1.1和elasticsearch。虽然以下代码正常工作：

>>> from accounts.models import CustomUser
>>> SearchQuerySet().models(CustomUser)
[<SearchResult: accounts.customuser (pk=u'552bc0ac1d41c80fe8015208')>]

但是，当我跑步时

>>> SearchQuerySet()

我在stacktrace中遇到以下错误：

AttributeError: 'NoneType' object has no attribute '_meta'

我无法弄清楚如何在SearchQuerySet结果中指定模型（可选），并且没有指定它给出错误的模型。

django haystack AttributeError：＆＃39; NoneType＆＃39;对象没有属性＆＃39; _meta＆＃39;
