Question

当我运行python manage.py syncdb时会发生这种情况。当我运行python manage.py syncdb --mysite.settings时也会发生这种情况。不知道从哪里开始：django无法识别我的设置文件，我不知道为什么或如何纠正它。

python ../manage.py syncdb
Traceback (most recent call last):

    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.

来自settings.py

DATABASES = { 
    'default': {
        'ENGINE': 'postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'xxx',                      # Or path to database file if using sqlite3.
        'USER': 'xxx',                      # Not used with sqlite3.
        'PASSWORD': 'xxx',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }   
}

我非常确信它没有找到合适的设置文件。

您好我假设您正在使用heroku测试您的应用并尝试连接到本地数据库？如果是这样，请务必删除这行代码：

# Parse database configuration from $DATABASE_URL
  import dj_database_url
  DATABASES['default'] =  dj_database_url.config()

# Honor the 'X-Forwarded-Proto' header for request.is_secure()
  SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https')

当您要连接到另一台服务器上的数据库时添加它。

正确的看起来像这样。

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': '',                      # Or path to database file if using sqlite3.
        'USER': '',                      # Not used with sqlite3.
        'PASSWORD': '',                  # Not used with sqlite3.
        'HOST': 'localhost', # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

编辑：将主机更改为localhost以反映评论＆amp; manage.py

根据您运行syncdb的方式

python manage.py syncdb --mysite.settings

确保您的manage.py文件具有指定的正确DJANGO_SETTINGS_MODULE

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

然后，您应该能够在没有--mysite.settings

的情况下运行syncdb

python manage.py syncdb

Django和venv：settings.DATABASES配置不正确。请提供ENGINE值
