干草堆搜索很多到很多领域都不行 [英] Haystack search on a many to many field is not working
问题描述
我正在尝试在具有多个字段的模型上运行搜索,并且我想使用此字段过滤搜索。
I'm trying to run a search on a model that has a many to many field, and I want to filter the search using this field.
这是我当前的代码:
search_indexes.py
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()]
listing_text.txt
listing_text.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 %}
尝试做一个简单的搜索,如:
I'm trying to do a simple search like:
search_results = SearchQuerySet().filter(category=query_text).filter
它返回一个空列表。感谢提前。
it returns an empty list. Thanks in advance.
推荐答案
阅读代码我认为问题在这里:
Reading your code I think the problem is here:
{% for category in obj.category.all %}
{{ category.name }}
{% endfor %}
类别不是一个对象,是一个MultiValueField。也许如果你尝试这样的东西:
Category is not an object, is a MultiValueField. Maybe if you try something like:
{% for category in object.category.all %}
{{ category.name }}
{% endfor %}
object.category.all 而不是obj.category.all。我不知道解决方案是这样的,但我确定错误可能在这3行。
object.category.all instead of obj.category.all. I'm not sure the solution is this, but I'm pretty sure the error could be in this 3 lines.
