Xapian motorlu Django-samanlık: model ManyToManyField

Question

içeriyorsa update_index çalıştırılamıyor Django'yu 1.7'ye yükselttikten sonra update_index yönetim komutunu çalıştıramıyorum.

KeyError: u'manager' 

Ben python2.7.6, Django 1.7, django-samanlık 2.3.1, arama motoru kullanmak: Xapian

Sorun görünür düşünüyorum çünkü 1.7 eklenti yönteminden Django ManyRelatedManager çağrısı() ve şimdi /haystack/fields.py dosyasında bu durum ateşleniyor.

if callable(current_object): 
    return current_object() 

Ama çağrı MANAGER_NAME içinde

biz uygun yöntemle

def __call__(self, **kwargs): 
     # We use **kwargs rather than a kwarg argument to enforce the 
     # `manager='manager_name'` syntax. 
     manager = getattr(self.model, kwargs.pop('manager')) 

sayesinde görebileceğiniz nasıl tanımlanmalıdır.

Answer 1

Dizeler veya tamsayılar dizisini döndürmek için özel bir yöntem kullanın (çok karmaşık bir indeks alanında daha karmaşık bilgileri saklamak istiyorsanız, dize desenlerini kullanın). Faceting ve otomatik tamamlanması için alanlar dahil olmak üzere solr için

class MyModelIndex(indexes.SearchIndex, indexes.Indexable): 
    my_m2m_field = indexes.CharField() 

    def prepare_my_m2m_field(self, my_model): 
     return [m2m.prop for m2m in my_model.m2m_field.all()] 

Saha beyanı:

<field name="my_m2m_field" type="text_general" indexed="true" stored="true" multiValued="true"/> 
<field name="my_m2m_field_exact" type="string" indexed="true" stored="false" multiValued="true"/> 
<field name="my_m2m_field_ac" type="ngram" indexed="true" stored="true" multiValued="true" 
     termVectors="true" termPositions="true" termOffsets="true"/> 
<copyField source="my_m2m_field" dest="emotion_exact" /> 
<copyField source="my_m2m_field" dest="emotion_ac" />
