Question

我正在尝试在Heroku上部署网络。当我运行heroku run python manage.py migrate时，我会收到一些错误： django.core.exceptions.ImproperlyConfigured: Set the DJANGO_SENTRY_DSN environment variable

我阅读了Cookiecutter上的文档，该文档说我必须指定这些值。但它并没有告诉我目的和方法是什么。我想知道我真的必须指定所有这些值吗？

DJANGO_AWS_ACCESS_KEY_ID    
DJANGO_AWS_SECRET_ACCESS_KEY    
DJANGO_AWS_STORAGE_BUCKET_NAME  
DJANGO_SENTRY_DSN
DJANGO_SENTRY_CLIENT
DJANGO_SENTRY_LOG_LEVEL 
DJANGO_MAILGUN_API_KEY  
DJANGO_MAILGUN_SERVER_NAME

Answer 1

您可以在此处查看所有必要的设置：http://cookiecutter-django.readthedocs.io/en/latest/settings.html

通常，您可以为它定义一个空白值，如：

heroku config：设置DJANGO_AWS_ACCESS_KEY_ID =''

具体来说，如果您不上传到S3，可以将 AWS 值留空，如果禁用哨兵，可以将 SENTRY 值留空，然后您可以离开如果您禁用mailgun，则 MAILGUN 应用。

Answer 2

您正在使用/config/settings内的production.py设置，方法是运行以下行：

heroku config:set DJANGO_SETTINGS_MODULE='config.settings.production'

为heroku创建一个单独的设置文件，而不是SENTRY和其他服务，否则只需取消注释初始化这些服务的行。如果您不使用aw，那么您还希望保留/media和/static本地。
