我完全按照heroku在 https://devcenter.heroku.com/articles/django 上指定的方式进行操作

但是当我运行 heroku run python manage.pysyncdb

它的说法是ImproperlyConfigured:settings.DATABASES配置不正确。请提供 ENGINE 值。检查设置文档以获取更多详细信息。

这就是我的 settings.py 文件的样子。我尝试了所有我找不到的解决方案似乎没有帮助

django_synapse 项目的 Django 设置。

# 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')

# Allow all host headers
ALLOWED_HOSTS = ['*']

# Static asset configuration
import os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_ROOT = 'staticfiles'
STATIC_URL = '/static/'

STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)

最佳答案

苏丹和乔都是正确的,如果你把它们放在一起并挖掘一下它的工作原理,我只是想通过添加对我有帮助的内容来更清楚地阐述它。这些instructions Heroku 网站上解释了如何设置它,包括 Sultan 提到的内容,将此部分添加到 settings.py:

# 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')

# Allow all host headers
ALLOWED_HOSTS = ['*']

# Static asset configuration
import os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
STATIC_ROOT = 'staticfiles'
STATIC_URL = '/static/'

STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)

然后,(以及这些说明中未提及的内容)在您的 Heroku 帐户中转到您的数据库部分并选择您要使用的数据库。转到“连接设置”(两个相反方向的小箭头)并选择 Django 选项。该代码应该类似于 Joe 提到的:

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'your_db_name',
'HOST': 'your_host',
'PORT': '5432',
'USER': 'your_db_user_name',
'PASSWORD': 'your_password',
}
}

将其粘贴到 settings.py 文件的底部并同步您的数据库。
