Python settings.DATABASES配置不正确（Elasticsearch）

我正在使用elasticsearch作为Django应用程序的数据库。但是每当我运行

python manage.py rebuild\u index

时，我都会出现以下错误：

我还使用Haystack作为我的搜索引擎。Haystack连接的My settings.py是：

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.elasticsearch2_backend.Elasticsearch2SearchEngine',
        'URL': 'http://127.0.0.1:9200/',
        'INDEX_NAME': 'haystack',
    },
}

在

manage.py

所在的位置创建一个名为

db.sqlite3

的文件，然后运行您正在运行的程序

显示发生错误时的数据库设置我不理解数据库部分。我应该声明数据库设置还是HAYSTACK_连接将扮演数据库连接的角色？？如果我必须编写数据库设置，我应该如何编写以将我的django应用程序与elasticsearch连接？否haystack连接与数据库不同，您需要在设置文件中声明数据库设置，否则它将无法运行我应该在数据库设置中编写什么？除了elasticsearch，我不想使用任何其他数据库。如何为elasticsearch配置数据库？这不会将所有数据保存在sqlite中吗？我还不明白到底发生了什么。你能详细说明一下吗？如果可能，请与meno开始“聊天”，当您使用haystack时，它将重定向到该数据库，该数据库仅用于使django正常运行。我创建了一个数据库，因此我使用它

“default”：{'ENGINE'：'django.db.backends.postgresql_psycopg2'，'NAME'：'core'，'USER'：'USER'，'USER'，'PASSWORD'：'USER'，'HOST'：'10.10.105.253'，'PORT'：''，}

我得到错误

值错误：需要属性名称：第11行第10列（char 274）

请稍等。页面加载速度非常慢。请看我的新问题。它是关于

RequestError:TransportError（400，u'parsing_exception'）

HAYSTACK_CONNECTIONS = {

        'INDEX_NAME': 'haystack',
    },
}

DATABASES = {
