wsgi.py
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings.prod") # mysite.settings.prod when in prod
application = get_wsgi_application()

我找到了我的解决方案。
步骤 1
将其添加到生产设置文件(此代码的来源来自此处(：
# Logging
LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'handlers': {
'console': {
'class': 'logging.StreamHandler',
},
},
'loggers': {
'django': {
'handlers': ['console'],
'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'),
},
},
}
步骤 2
确保在本地运行python manage.py collectstatic --noinput并使用git push heroku master将代码推送到 Heroku 服务器。在 Heroku CLI 中也使用heroku run python manage.py collectstatic --noinput执行此操作
步骤 3
使用heroku logs --tail捕获将通过调用步骤 1 中的代码突出显示的任何错误。就我而言，我有：
ValueError: Missing staticfiles manifest entry for 'assets/css/main.css'
此外，我使用以下代码来消除有关 psycog 二进制库的警告。
conn = psycopg2.connect(DATABASE_URL, sslmode='require')
并import psycopg2在我的基本设置文件中。
最后，在其他地方有一些关于白噪声和静态文件目录的讨论。
我使用了以下设置：
import os
import dj_database_url
import django_heroku
import psycopg2
# import sys
# from secrets import *
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
PROJECT_ROOT = os.path.dirname(os.path.abspath(__file__))

最后，在wsgi.py文件中，确保此配置：
