django - 带有 Elasticsearch 的 Haystack 拒绝创建搜索索引

Question

我正在使用连接到 Elasticsearch 服务器的 Django(主分支)和 Haystack(主分支)。 Python 版本是 3.4。

搜索索引类如下所示:

class PageIndex(indexes.SearchIndex, indexes.Indexable):
    text = fields.EdgeNgramField(document=True)
    name = fields.EdgeNgramField(model_attr='name', boost=2)
    tags = fields.EdgeNgramField(model_attr='tags', boost=1.5)
    description = fields.EdgeNgramField(model_attr='description_summary', boost=0.9)

    def get_model(self):
        return Page

    def index_queryset(self, using=None):
        return self.get_model().objects.filter(created__lte=datetime.datetime.now())

当我尝试创建索引时，出现以下错误:

> python manage.py update_index                                                                                                                                                                                                                                             Indexing 7 communities

您收到此错误消息是因为在 Django >= 1.6 Options.module_name 更改为 .model_name (这是 widley 滥用的非公共(public) API)所以您只需要更改 haystack 代码 module_name
