django-haystack 对多对多字段( ManyToManyField )进行索引

源自： Django Haystack and Taggit - Stack Overflow

我的错误栈如下：

Is there anybody using Django taggit with haystack? How can we make tags field indexable by haystack?

I have tried:

class EventIndex(indexes.SearchIndex, indexes.Indexable):text = indexes.CharField( model_attr='descr_en', document=True, use_template=True)text_tr = indexes.CharField(model_attr='descr_tr')tags = indexes.MultiValueField()def prepare_text(self, obj):return '%s %s' % (obj.title_en, obj.descr_en)def prepare_text_tr(self, obj):return '%s %s' % (obj.title_tr, obj.descr_tr)def prepare_tags(self, obj):return [tag.name for tag in obj.tags.all()]def get_model(self):return Event

And i am using a custom searchqueryset for multilingual search :

class MlSearchQuerySet(SearchQuerySet):def filter(self, **kwargs):"""Narrows the search based on certain attributes and the default operator."""if 'content' in kwargs:kwd = kwargs.pop('content')currentLngCode = str(get_language())lngCode = settings.LANGUAGE_CODEif currentLngCode == lngCode: kwdkey = "text" kwargs[kwdkey] = kwdelse:kwdkey = "text_%s" % currentLngCodekwargs[kwdkey] = kwdif getattr(settings, 'HAYSTACK_DEFAULT_OPERATOR', DEFAULT_OPERATOR) == 'OR':return self.filter_or(**kwargs)else:return self.filter_and(**kwargs)

To get the tags into the search index we added them to our content template file eg

{{ object.title }}
{{ object.body }}
{% for tag in object.tags.all %} {{ tag.name }} {% endfor %}
{{ object.user.get_full_name }}

We also include it as a MultiValueField

tags = indexes.MultiValueField()def prepare_tags(self, obj):return [tag.name for tag in obj.tags.all()]

Haven't had success trying to make boost work in either case, but the search definitely indexes them correctly.

I have updated my question in order to represent my real code structure better. Because i am not getting any tags related search results with the ways you suggest...

can you include your text template? if your tags are in there they should get indexed, they will be treated the same as any other content in your template.

in 'event_text.txt' i have : {{ object.title }} {{ object.descr }} {% for tag in object.tags.all %} {{ tag.name }} {% endfor %}

hmm seems ok to me - sorry to ask what may be a silly question, but just to make sure; you are reindexing after each change, correct? (ie run "python manage.py rebuild_index")

ah you probably also need to add tags to your prepare_text method - not confident on that but seems like its missing (still new to haystack, you're past my basic knowledge now)
