问题
I am using:
django: 1.9.7
django-haystack: 2.5.0
whoosh: 2.7.4
search_index.py
class ProfileIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
last_name= indexes.CharField(model_attr='last_name')
content_auto = indexes.EdgeNgramField(model_attr='first_name')
def get_model(self):
return User
def index_queryset(self, using=None):
"""Used when the entire index for model is updated."""
return self.get_model().objects.all()
user_text.txt
{{ object.last_name }}
in the views.py i try:SearchQuerySet().count() => returns 0
SearchQuerySet().all() => returns None
I've read about some issues with the latest Whoosh implementation in django-haystack but i'm not sure if the problem is in my code

Please see my answer here:
Django Haystack & Whoosh Search Working, But SearchQuerySet Return 0 Results
There is a bug in Django-Haystack with Woosh that means if you use an Ngram or EdgeNGram field SearchQuerySet().count() and SearchQuerySet().all().count() will always return 0 unless you specify a filter.
e.g.
SearchQuerySet().all().count()
>> 0
SearchQuerySet().all().exclude(content='thisshouldnotmatchanything').count()
>> 14 [the total number of indexed objects]
