settings.DATABASES配置不當

我使用elasticsearch數據庫爲我的Django應用程序（Elasticsearch）。但每當我運行python manage.py rebuild_index我想出了以下錯誤：settings.DATABASES配置不當

    raise ImproperlyConfigured("settings.DATABASES is improperly configured. " 
django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

主要錯誤是：

raise ImproperlyConfigured("settings.DATABASES is improperly configured. " 
    django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

我也是用草堆我的搜索引擎。我對草堆連接settings.py是：

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

顯示數據庫的設置發生了誤差，有 – Exprator

我我不瞭解數據庫部分。我應該聲明DATABASE設置還是HAYSTACK_CONNECTIONS將扮演數據庫連接的角色？如果我必須編寫數據庫設置，應該如何編寫它以將我的django應用程序與elasticsearch連接起來？ –

不是乾草堆連接與數據庫不同，您需要在設置文件中聲明DATABASE設置，否則將不會運行 – Exprator

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.sqlite3', 
     'NAME': 'mydatabase', 
    } 
}

創建一個名爲db.sqlite3文件，其中manage.py是，然後運行你正在運行什麼

將不會保存所有的數據在sqlite中嗎？我還沒有理解到底發生了什麼。你能詳細解釋一下嗎？如果可能的話，請啓動「聊天」跟我 –

沒有，當您使用草垛會重定向到，數據庫只是爲了使Django的正常運行 – Exprator

我有一個數據庫中創建的，所以我用它'「默認」：{ 'ENGINE'：'django.db.backends.postgresql_psycopg2'， 'NAME'：'core'， 'USER'：'user'， 'PASSWORD'：'user'， 'HOST'：'10.10.105.253' ' 'PORT'：'」， }'我被錯誤'ValueError異常：期待屬性名：行11列10（字符274）' –
