部署django app后出现Server Error (500)

Question

我必须使用Django部署PyTorch模型，我有静态文件，包括图像，CSS和javascript文件。通过使用whitenoise和禁用COLLECTSTATIC部署后，我使用Heroku部署后得到服务器错误。需要帮助。我在下面附上了我的settings.py文件代码以供参考

Answer 1

你应该把应用程序迁移到数据库。

试试这个:

第一步:你应该在终端登录到heroku。

heroku login

，然后试试这个:

heroku run python manage.py migrate

，你也可以DEBUG=True让Django显示错误。

Answer 2

你可以试试;

DEBUG = True
ALLOWED_HOSTS = ['*']
