如何在Haystack中仅返回特定类型的索引对象 [英] How to return only indexed objects of a specific type in Haystack

问题描述

有没有办法使用SearchQuerySet并将结果限制在特定的索引模型？ ie如果我添加了Note和NoteIndex到Haystack，我可以拉出对应于Note实例的结果？

编辑：

$ b $我已经看了一下，发现有一个名为django_ct的保留字段存储在每个索引模型上。是否可以过滤此字段？什么价值观？

双重编辑：

Nevermind。阅读Haystack源代码后，django_ct在内部是'appname.modelname'，可以通过SearchQuerySet.filter（django_ct ='appname.modelname'）查询

解决方案

根据Haystack文档，SearchQueryset对象有一个名为models（）的方法，将结果限制为这些模型。

例如

  SearchQuerySet（）。models（BlogEntry，Comment）.filter（content ='foo'）
  

如您所见，它使用实际的模型类。我的猜测是它使用它来查找内容类型来执行过滤器。

Is there any way to use SearchQuerySet and restrict the results to only a specific indexed model? i.e. If i add Note and NoteIndex to Haystack, can I pull out just results that correspond to Note instances?

EDIT:

I have had a look and found that there is a reserved field named django_ct that is stored on every indexed model. Is it possible to filter on this field? What values does it take?

DOUBLE EDIT:

Nevermind. After reading the Haystack source code, django_ct is 'appname.modelname' internally and can be querired with SearchQuerySet.filter(django_ct = 'appname.modelname')

解决方案

According to the Haystack documentation, a SearchQueryset object has a method called models() that restricts the results to those models.

e.g.

SearchQuerySet().models(BlogEntry, Comment).filter(content='foo')

As you see, it uses the actual model class. My guess is that it uses this to lookup the content-type to perform filter.
