在ElasticSearch/Django中重建搜索索引时出错

Question

当我跑的时候

./manage.py search_index --rebuild

我得到以下错误：

 elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'Root mapping definition has unsupported parameters:  [bodystyle : {type=text}] [model : {type=text}] [carclass : {type=text}] [version : {type=text}]')

我试着改变我的ElasticSearch的版本。我的当前版本是：

$curl-xget'localhost:9200'{“name”：“mokbeeq”,“cluster_name”：“elasticsearch”,“cluster_uuid”：“pf_z62bbtl-jq31hsuahqa”,“version”：{“number”：“5.6.8”,“build_hash”：“688ecce”,“build_date”：“2018-02-16t16:46:30.010z”,“build_snapshot”：false,“lucene_version”：“6.6.1”},“tagline”：“您知道，用于搜索”}

我的documents.py代码如下：

from django_elasticsearch_dsl import Document
from django_elasticsearch_dsl.registries import registry
from products.models import Product_Model


@registry.register_document
class CarDocument(Document):
    class Index:
        # Name of the Elasticsearch index
        name = 'cars'
        # See Elasticsearch Indices API reference for available settings
        settings = {'number_of_shards': 1,
                    'number_of_replicas': 0}

class Django:
    model = Product_Model # The model associated with this Document

    # The fields of the model you want to be indexed in Elasticsearch
    fields = [
        'model',
        'version',
        'carclass',
        'bodystyle',
    ]

是否迁移到elasticsearch版本6/7？尝试升级django_elasticsearch_dsl版本
