django-haystack doesn't support 1.9 django?

Question

Django

Good afternoon. Decided to try full-text search. I did everything according to the haystack instructions. I use whoosh.

class NewsIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    title = indexes.CharField(model_attr='title')
    article = indexes.CharField(model_attr='artcile')

    def get_model(self):
        return News

    def index_queryset(self, using=None):
        """Used when the entire index for model is updated."""
        return self.get_model().objects.filter(pub_date__lte=datetime.datetime.now())

When executing a search query, it throws the following error:

Traceback:
File "C:\Python 3.5\lib\site-packages\haystack\query.py" in post_process_results
213. index = ui.get_index(model)

Answer 2

When I upgraded to django 1.9, I also ran into a problem that there are search results, but the object is not available, fell off with the error Model could not be found for SearchResult.
This case, it seems to me, is very similar to mine. I solved my problem like this.
Uninstalled haystack first: pip uninstall django-haystack
Then installed it using a commit that was not in the 2.4.1 branch
-e git://github.com/django-haystack/[email protected]#egg=haystack
