settings.DATABASES 配置不正确（Elasticsearch）

Question

我正在使用 elasticsearch 作为我的 Django 应用程序的数据库。但是每当我运行python manage.py rebuild_index 时，都会出现以下错误：

Traceback (most recent call last):
  File "manage.py", line 22, in <module>

    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.

主要错误是：

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.

我也在使用 Haystack 作为我的搜索引擎。我的 Haystack 连接的 settings.py 是：

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',
    }
}

创建一个名为db.sqlite3 的文件，其中manage.py 是，然后运行您正在运行的文件
