Добрый день. Решил попробовать полнотекстовый поиск. Сделал всё по инструкции haystack. Использую 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())
При выполнение поискового запроса вываливает следующую ошибку:
Traceback:
