Django haystack elasticsearch自動完成功能不起作用

Question

在數據庫中，我有名稱爲「Product 1」，「Product 2」等的產品。搜索「Produc」應該返回許多值，但我什麼也沒有得到。 我的指數：

from haystack import indexes 

from .models import Product 


class ProductIndex(indexes.SearchIndex, indexes.Indexable): 
    text = indexes.CharField(document=True) 
    id = indexes.IntegerField(model_attr='id') 
    title = indexes.CharField(model_attr='title') 
    slug = indexes.CharField(model_attr='slug') 
    description = indexes.CharField(model_attr='description') 
    content_auto = indexes.NgramField(model_attr='title') 

    def get_model(self): 
     return Product 

    def index_queryset(self, using=None): 
     return self.get_model().objects.all() 

結果從外殼：

In [3]: SearchQuerySet().autocomplete(content_auto='produc') 
Out[3]: [] 

In [4]: SearchQuerySet().autocomplete(content_auto='product') 
Out[4]: [<SearchResult: catalogue.product (pk=u'4')>, <SearchResult:  
catalogue.product (pk=u'9')>, <SearchResult: catalogue.product 
(pk=u'11')>, <SearchResult: catalogue.product (pk=u'16')>, 
<SearchResult: catalogue.product (pk=u'23')>, <SearchResult: 
catalogue.product (pk=u'28')>, <SearchResult: catalogue.product 
(pk=u'30')>, <SearchResult: catalogue.product (pk=u'35')>, <SearchResult: 
catalogue.product (pk=u'42')>, <SearchResult: catalogue.product 
(pk=u'47')>, <SearchResult: catalogue.product (pk=u'54')>, <SearchResult: 
catalogue.product (pk=u'59')>, <SearchResult: catalogue.product 
(pk=u'61')>, <SearchResult: catalogue.product (pk=u'66')>, <SearchResult: 
catalogue.product (pk=u'73')>, <SearchResult: catalogue.product 
(pk=u'78')>, <SearchResult: catalogue.product (pk=u'80')>, <SearchResult: 
catalogue.product (pk=u'85')>, <SearchResult: catalogue.product 
(pk=u'92')>, u'...(remaining elements truncated)...'] 

Answer 1

如果您剛添加的content_auto場，您可能需要運行manage.py rebuild_index創建更新的索引。
