Question

每当我在django Haystack中使用SearchQuerySet指定.values（）时，我就会得到一个Keyerror。例如，

required_output = SearchQuerySet()[:10]

工作正常。但无论何时，我都会执行以下操作，每次都会抛出KeyError。

required_output = SearchQuerySet().values('title', 'slug')[:10]

这里是错误的引用：

您使用的是什么版本的django-haystack？看起来django-haystack GitHub上有一个未解决的问题。还有一个补丁应该修复它。看起来你必须要么等待合并，要么在本地修补它。
