Python Django haystack在国外场地上刻面

是否可以通过搜索索引在外部字段属性上刻面

search_index.py

class ProductIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.EdgeNgramField(
        document=True, use_template=True,
        template_name='/home/wilkinj33/bargainforest/bargainforestenv/motorclass/templates/search/indexes/product_text.txt'
        )

    title = indexes.EdgeNgramField(model_attr='title')
    retailer = indexes.CharField(model_attr='retailer', faceted=True)
    price = indexes.IntegerField(model_attr='price', faceted=True)
    barcode = indexes.CharField(model_attr='barcode')

    def get_model(self):
        return Product

    def index_queryset(self, using=None):
        """Used when the entire index for model is updated."""
        return self.get_model().objects.filter(timestamp__lte=timezone.now())

我想对下面的模型命名属性

class top_category(models.Model):
    class Meta:
        verbose_name_plural = 'Top Categories'

    name = models.CharField(max_length=500)

    def __str__(self):
        return self.name

通过导入相关模型并以正常方式引用模型属性解决。通过导入相关模型并以正常方式引用模型属性解决。
