Question

当debug设置为false时，我收到服务器错误（500），但是当debug = True

时，该站点正常工作

这是Heroku日志： [编辑：在DJANGO日志中更改后的新日志文件]

起初我有一个内部服务器错误，但那是因为我没有把我的SENDGRID API放在我的settings.py中，在添加之后我得到了SERVER ERROR（500）

这是 settings.py

EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = '****'
EMAIL_HOST_PASSWORD = '****'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_BACKEND = "sgbackend.SendGridBackend"
SENDGRID_API_KEY = "***"

ALLOWED_HOSTS = ['www.xxx.com', 'xxx.com']

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'whitenoise.middleware.WhiteNoiseMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
 ###
 ]

     DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

import dj_database_url

db_from_env = dj_database_url.config()
DATABASES['default'].update(db_from_env)

MEDIA_URL = '/media/'
CKEDITOR_UPLOAD_PATH = "uploads/"
CKEDITOR_IMAGE_BACKEND = "pillow"
CKEDITOR_JQUERY_URL = '//code.jquery.com/jquery-3.1.1.min.js'
STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles')
STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(PROJECT_ROOT, 'static'),
)
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

MEDIA_ROOT = os.path.join(PROJECT_ROOT, 'static/media')

静态文件加载在Debug = False

中

这是我尝试 heroku本地网络

的时候

 [WARN] No ENV file found
    22:19:44 web.1   |  [2017-07-29 22:19:44 +0000] [7476] [INFO] Starting gunicorn 19.7.1

我得到了一个不好的请求（400）

PS：所以，有些图片也没有加载，这可能是静态文件的问题吗？但我的CSS加载了一些其他图像。

[编辑]未加载的图像是我在django的管理页面上传时上传的图像。在git push heroku master之后，图片没有加载。

这是我的 wsgi.py

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "techzu.settings")

application = get_wsgi_application()

from whitenoise.django import DjangoWhiteNoise
application = DjangoWhiteNoise(application)

[编辑：ValueError：无法找到'style.css'文件。]

Answer 1

在 settings.py

中添加了此内容

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console'],
             'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'),
        },
    },
}

在日志中收到错误显然，远程服务器和本地计算机中文件夹的名称不匹配

Answer 2

关闭调试时。您需要在列表中提供ALLOWED_HOSTS。请查看Django文档了解更多..

 Debug = False
ALLOWED_HOSTS = ['xyz.com']

Answer 3

你不能在Heroku上使用SQLite3。切换到Postgres。

Answer 4

尝试通过以下方式进行迁移：

heroku运行python manage.py makemigrations

heroku运行python manage.py迁移

我遇到了同样的问题，但这解决了。

Answer 5

您需要提供ALLOWED_HOSTS

Debug = False
ALLOWED_HOSTS = [".herokuapp.com"]

和Heroku你应该使用PostgreSQL

Answer 6

就我而言，这是由于之间的冲突 django staticfiles 和 django _heroku staticfiles

我不得不禁用其中之一。

要么这样做，

 ` INSTALLED_APPS={
            .
            .
            #django.contrib.staticfiles,
  }
  django_heroku.settings(locals())` #in end of settings.py

或者这样做

    `INSTALLED_APPS={
            .
            .
            django.contrib.staticfiles,
      }
     django_heroku.settings(locals(),staticfiles=False)` #in end of settings.py

或者，如果您正在使用 whitenoise ，请禁用 django 和 django_heroku 的静态文件。

当Debug = False时，Heroku服务器错误（500），whitenoise找不到style.css
