Django haystack multivalued不起作用

Question

我已经为我的索引(haystack)添加了一个MultivaluedField,我需要搜索ManyToMany相关字段,但它不起作用.

该引擎是WHOOSH.

这是我的索引的样子:

 class PostIndex(SearchIndex):
     text = CharField(document=True, use_template=True)
     author = CharField(model_attr='author') 
     body = CharField(model_attr='body') 
     pub_date = DateTimeField(model_attr='publish') 
     regions = MultiValueField() 

 def prepare_regions(self, obj):
     return [region.name for region in obj.regions.all()]

这就是我的模型的样子:

 class Post(models.Model):

     title           = models.CharField(_('title'), max_length=200)
     author          = models.ForeignKey(User, blank=True, null=True)
     body            = models.TextField(_('body'), )
     allow_comments  = models.BooleanField(_('allow comments'), default=True)
     publish         = models.DateTimeField(_('publish'), default=datetime.datetime.now)
     categories      = models.ManyToManyField(Category, blank=True)
     tags            = TagField()
     objects         = PublicManager()

     regions         = models.ManyToManyField(Region, blank=True)

如果我使用SearchQuerySet().filter(region__in = words_list)它可以工作.问题是我不知道用户何时搜索某个区域或其他字段,因此我必须使用SearchQuerySet().filter(content__icontains = words_list).并且以这种方式找不到任何东西.

谢谢

谢谢!!

尝试 ：

class PostIndex(SearchIndex):
 text = CharField(document=True, use_template=True)
 author = CharField(model_attr='author') 
 body = CharField(model_attr='body') 
 pub_date = DateTimeField(model_attr='publish') 

 regions = CharField(model_attr='regions')
