将 Cookiecutter-Django 应用程序部署到 Heroku 时出错
Error deploying Cookiecutter-Django app to Heroku
我正在使用 Django Cookiecutter 样板，使用 Docker。在本地一切正常，所以现在我正在尝试按照本指南将应用程序部署到 Heroku：Deployment on Heroku。我正在使用 Django 3 和 Rest 框架。 Docker 用于开发。
运行配置命令后，我推送到 Heroku master 并收到此错误：
Error while running '$ python manage.py collectstatic --noinput'.
跟踪如下：

在错误下方，我收到消息以使用此命令禁用收集静态：
$ heroku config:set DISABLE_COLLECTSTATIC=1
我运行上面的命令并继续但是下一个命令不起作用因为Heroku找不到manage.py文件
heroku run python manage.py createsuperuser
我在网上搜索了各种部署指南，但看起来在 Heroku 上部署 Django 应用程序并不像在 Rails.
上那样简单
错误提示应用缺少环境变量SENDGRID_API_KEY。这听起来像是一个文档错误，如果您有时间，我将不胜感激 report it。
基本上，Heroku 的部署假定您使用 Mailgun 作为电子邮件服务，因为它要求您 运行:
heroku addons:create mailgun:starter
但是，您似乎选择了 Sendgrid，这是最近引入的一个选项（参见 PR #2435），但此页面未相应更新。
要解决您的问题，您需要添加 Sendgrid add-on to your app. Once added, from Heroku, you should be able to click the add-on to access your Sendgrid dashboard where you need to create an API key as per this guide and add it the config vars of you Heroku app, following this guide。
