Question

我有餐厅和评论模型如下所示。评论模型有一个ForeignKey到餐厅。如何在“注释”模型的某些“餐厅”字段和注释字段中执行搜索，以返回餐馆实例列表？

由于

class Restaurant(models.Model):

    name = models.CharField(max_length=100)
    country=models.ForeignKey(Country)
    city=models.ForeignKey(City)
    street=models.CharField(max_length=100)
    street_number=models.PositiveSmallIntegerField()
    postal_code=models.PositiveIntegerField(blank=True, null=True)
    slug = models.SlugField(unique=True)


class Comment(models.Model):

    user = models.ForeignKey(User)
    restaurant = models.ForeignKey(Restaurant)
    submit_date = models.DateTimeField(blank = True, null = False)
    comment = models.TextField()

Answer 1

我认为你应该阅读手册：http://django-haystack.readthedocs.org/en/latest/tutorial.html

寻找多元化：

class RestaurantIndex(indexes.SearchIndex): 
     comments = indexes.MultiValueField() 
     def prepare_comments(self, obj): 
         return [a for a in obj.comment_set.all()]

使用django-haystack在几个表中搜索
