有人能告诉我如何使用属性过滤django-haystack的全文搜索结果吗？我在他们的网站上浏览了教程,但我仍然确定如何使用干草堆.
例如,假设我有一个产品类:
class Product(models.Model):
title = models.CharField(max_length=200)
description = models.TextField()
category = models.CharField(max_length=10)
color = models.CharField(max_length=10)
如果我想在标题和描述上提供全文搜索,并在类别和颜色上过滤(基于下拉列表,而不是自由文本) - 我需要做什么？我可以使用haystack附带的表单和视图吗？
谢谢.
我正试图用后嘶嘶声设置干草堆.当我尝试生成索引[或任何索引命令]时,我收到:
TypeError: Item in ``from list'' not a string
如果我完全删除我的search_indexes.py我得到相同的错误[所以我猜它根本找不到该文件]
什么可能导致这个错误？它设置为自动发现,我确定我的应用程序已安装,因为我正在使用它.
完全追溯:

现在,当我尝试更新或重建索引时,它失败了
Failed to add documents to Solr: [Reason: None]
.
对于所有查询返回0结果,所有搜索也都是错误的.如果我改变为嗖嗖,这项工作.但是,我有一个RealTimeSearch索引集,并且在模型创建期间,我没有得到关于无法写入搜索索引的警告.(我假设数据正在被写入solr索引.
通过直接进入solr启动的端口,我可以看到solr正在运行.
拥有视频模型和搜索索引.使用Django-haystack和Solr.需要按日期/周/月/年的视频视图对结果进行排序.是否可以通过最后一天/周/月/年的观看信息更新搜索索引？
如果只需按日期和总计的视图排序,则可以仅为查看一天的视频更新索引,其中当前视图等于0.
每隔几个小时使用update_index看起来不是一个好主意,因为现在它需要30分钟,所以将来可以采取更多.现在,搜索索引仅针对使用Celery异步任务的已更改对象进行更新.
我正在尝试使用django-haystack在Solr中为模型建立索引，但是它返回以下错误（使用rebuild_index或update_index时）：
Failed to add documents to Solr: [Reason: Error 404 Not Found]
这是search_indexes.py
from haystack import indexes
from haystack.indexes import SearchIndex
from jobpost.models import *
class JobIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
post_type = indexes.CharField(model_attr='post_type')
location = indexes.CharField(model_attr='location')
job_type = indexes.CharField(model_attr='job_type')
company_name = indexes.CharField(model_attr='company_name')
title = indexes.CharField(model_attr='title')
def get_model(self):
return jobpost
def index_queryset(self,**kwargs):
return self.get_model().objects.all()
干草堆连接：
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
'URL': 'http://127.0.0.1:8983/solr',
'SITECONF': 'jobpost.search_sites'
},
}
我已生成schema.xml多次重新启动solr ..将其放置在solr / conf中..不知道是什么问题
我有以下搜索
class ProductIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
destination = indexes.FacetIntegerField(
model_attr='hotel__destination__id')
country = indexes.FacetIntegerField(model_attr='hotel__country__id')
hotel_class = indexes.FacetCharField(model_attr='hotel__hotel_class')
hotel_type = indexes.FacetIntegerField(model_attr='hotel__hotel_type__id')
def get_model(self):
return Product
def index_queryset(self, using=True):
return self.get_model().objects.all()
class DestinationIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
content_auto = indexes.EdgeNgramField(model_attr="foo")
并在settings.py中进行以下设置
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE':
'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
'URL': 'http://127.0.0.1:9200/',
'INDEX_NAME': 'haystack',
},
'autocomplete': {
'ENGINE':
'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
'URL': 'http://127.0.0.1:9200/',
'INDEX_NAME': 'autcomplete',
}
}
但是当我说rebuild_indexes时,两个索引变得相同,它们根据两个索引类进行索引.但是我想要使用ProductIndex索引默认索引,并使用目标索引索引自动完成.
有任何想法吗？
我将 Django 1.5 与 django-haystack 2.0 和 elasticsearch 后端一起使用。我正在尝试通过精确的属性匹配进行搜索。但是，即使我同时使用__exact运算符和 Exact() 类，我也得到了“类似”的结果。我怎样才能防止这种行为？
例如：
# models.py
class Person(models.Model):
name = models.TextField()
# search_indexes.py
class PersonIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
name = indexes.CharField(model_attr="name")
def get_model(self):
return Person
def index_queryset(self, using=None):
return self.get_model().objects.all()
# templates/search/indexes/people/person_text.txt
{{ object.name }}
>>> p1 = Person(name="Simon")
>>> p1.save()
>>> p2 = Person(name="Simons")
>>> p2.save()
$ ./manage.py rebuild_index
>>> person_sqs = SearchQuerySet().models(Person)
>>> person_sqs.filter(name__exact="Simons")
[<SearchResult: people.person (name=u'Simon')>
<SearchResult: people.person (name=u'Simons')>]
>>> person_sqs.filter(name=Exact("Simons", clean=True))
[<SearchResult: people.person (name=u'Simon')> …我正在尝试将Django和Haystack与Elasticsearch一起用作Ubuntu 14.04的后端.我安装了Elasticsearch和Haystack.
