当DEBUG = False时，我的Django管理面板显示服务器错误（500）

Question

当我的DEBUG = False时显示“错误：-1”，而当我的DEBUG = True时显示“错误：-2”。

我将使用 python 3.7.7 和 django 3.0.4 。

我的settings.py文件是：-

---

DEBUG = False

ALLOWED_HOSTS = ["*"] 

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',

    'home.apps.HomeConfig',
]

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),

这是“ 错误：1 ”...。[当DEBUG = False时]

这是“ 错误：-2 ” ... [当DEBUG = True时]

但是在'DEBUG = True'的时间，我的管理页面已打开，但终端显示以下错误。

[15/Mar/2020 11:15:51] "GET /admin/login/?next=/admin/ HTTP/1.1" 200 1913

每当我尝试在浏览器中打开'/ admin /'时，都会出现错误，但是我的主页[127.0.0.1:8000]可以正常工作。

提前谢谢。

Answer 1

**最后的错误可以解决.. **

我们只能从settings.py删除三行

1> django_heroku.settings(locals()) 这行是在Heroku上部署Django应用所必需的。

2> STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

3> MIDDLEWARE = [ ... 'whitenoise.middleware.WhiteNoiseMiddleware', ]

当DEBUG = False时，第二行和第三行用于在网站上投放静态文件。

消除这三行错误后即可解决， 它将完美运行，没有任何错误。

谢谢您，特别感谢您Alasdair。
