将 django 项目部署到 heroku 时出现服务器错误 (500)

Question

这是我的项目的设置，在此设置中，我进行了不同类型的更改以使其正常工作，但我还没有完成

import os
import django_heroku

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/3.0/howto/deployment/checklist/

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = 'my_secret_key'

这里我把调试从真改成了假

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = False

ALLOWED_HOSTS = ['projects.herokuapp.com']

激活 Django-Heroku。

django_heroku.settings(locals())

这是 wsgi

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'TeckBlog.settings')

application = get_wsgi_application()
