... [transcription-index] as the final mapping would have more than 1 type: [doc, modelresult]
我在一个完全干净的Django上得到了上述错误（即删除了所有以前的迁移和sqlite.db）。 Elasticsearch是6.2.4，elasticsearch_dsl是6.1.0，Django是2.0.5。
然后我运行python manage.py makemigrations和python manage.py migrate，效果很好。在python manage.py createsuperuser之后，我可以登录，看看http://127.0.0.1:8000/admin/elasticsearchapp/transcription/是否为空，但是包含所有正确的字段(identifier, speaker, title, description, trans)。
当我尝试通过运行python manage.py populate来填充我的sqlite.db数据时出现问题，我得到了
raise BulkIndexError('%i document(s) failed to index.' % len(errors), errors)
elasticsearch.helpers.BulkIndexError: ('1 document(s) failed to index.', [{'index': {'_index': 'transcription-index', '_type': 'modelresult', '_id': 'elasticsearchapp.transcription.1', 'status': 400, 'error': {'type': 'illegal_argument_exception', 'reason': 'Rejecting mapping update to [transcription-index] as the final mapping would have more than 1 type: [doc, modelresult]'}
I have read several issues on this, but most of them refer to "Indices created in Elasticsearch 6.0.0 or later may only contain a single mapping type."。但是，我无法看到与我相关的方法？
