主なエラーは次のとおりです。私はまた私の検索エンジンのヘイスタックを使用しています

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. 

。ヘイスタック接続のための私のsettings.pyは次のとおりです。

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

Answer 1

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

ファイルを作成manage.pyがどこにあるdb.sqlite3と呼ばれ、その後、あなたは
