我正在为我的Django项目在Heroku上进行设置。我一直在按照文档的指导操作,但当我执行foreman start
时,出现了一个错误,我无法完全理解。我已经设置好了我的引擎文件,但它似乎不想工作。
完整跟踪信息:

有人建议使用
./manage.py diffsettings
命令并显示DATABASES部分:DATABASES = {'default': {'AUTOCOMMIT': True, 'ENGINE': 'django.db.backends.dummy', 'ATOMIC_REQUESTS': False, 'NAME': '', 'TEST_MIRROR': None, 'CONN_MAX_AGE': 0, 'TEST_NAME': None, 'TIME_ZONE': 'UTC', 'TEST_COLLATION': None, 'PORT': '', 'HOST': '', 'USER': '', 'TEST_CHARSET': None, 'PASSWORD': '', 'OPTIONS': {}}}
我似乎无法弄清它的含义,但表面上看起来不正确。
这是我认为与此问题相关的
settings.py
的一部分:import os
import dj_database_url
ON_HEROKU = os.environ.get('ON_HEROKU')
HEROKU_SERVER = os.environ.get('HEROKU_SERVER')
if ON_HEROKU:
DATABASES = {
'default': {

'NAME': 'postgresql',
}
}
else:
DATABASES = {

'USER': '',
'PASSWORD': '',

'PORT': '',

}
DATABASES['default'] = dj_database_url.config()

ALLOWED_HOSTS = ['*']
