我正在尝试对具有多对多字段的模型进行搜索,并且我想使用此字段过滤搜索。
这是我当前的代码:
search_indexes.py
class ListingInex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
business_name = indexes.CharField(model_attr='business_name')
category = indexes.MultiValueField(indexed=True, stored=True)
city = indexes.CharField(model_attr='city')
neighborhood= indexes.CharField(model_attr='neighborhood')
state = indexes.CharField(model_attr='state')
address = indexes.CharField(model_attr='address')
zip_code = indexes.CharField(model_attr='zip_code')
phone_number = indexes.CharField(model_attr='phone_number')
def get_model(self):
return listing
def index_queryset(self, using=None):
return self.get_model().objects.all()
def prepare_category(self, obj):
return [category.name for category in obj.category_set.all()]
列表文本.txt
{{ object.business_name }}
{{ object.state }}
{{object.city}}
{{object.zip_code}}
{{object.phone_number}}
{{object.neighborhood}}
{% for category in obj.category.all %}
{{ category.name }}
{% endfor %}
我正在尝试进行简单的搜索,例如:
search_results = SearchQuerySet().filter(category=query_text).filter
它返回一个空列表。提前致谢。
