Debug=False
部署时切换到Heroku应用程序时,出现一个有趣的500错误。我在部署时将Debug = True设置为仅用于尝试,它可以正常工作-因此,仅当将Debug设置为False时,此问题才出现。
我不确定从哪里开始。一些搜索使我相信这是引起问题的白噪声,但目前尚不清楚。命令:

我尝试按照此解决方案进行修复,但无济于事;
请参阅以下我的设置:

好吧-经过一番奋斗,我找到了解决我遇到的两个问题的解决方案。
问题1:无法查看heroku日志-源应用程序:我必须首先将LOGGING添加到settings.py文件:
LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'verbose': { 'format': ('%(asctime)s [%(process)d] [%(levelname)s] ' + 'pathname=%(pathname)s lineno=%(lineno)s ' + 'funcname=%(funcName)s %(message)s'), 'datefmt': '%Y-%m-%d %H:%M:%S' }, 'simple': { 'format': '%(levelname)s %(message)s' } }, 'handlers': { 'null': { 'level': 'DEBUG', 'class': 'logging.NullHandler', }, 'console': { 'level': 'DEBUG', 'class': 'logging.StreamHandler', 'formatter': 'verbose' } }, 'loggers': { 'testlogger': { 'handlers': ['console'], 'level': 'INFO', } } }
更重要的是使相关错误通过Heroku日志传播出去。为此,我在settings.py中编写了以下代码:
DEBUG_PROPAGATE_EXCEPTIOnS= True
这给了我一个与我的静态文件相关的错误。更具体地说,它给了我这个错误:
ValueError: Missing staticfiles manifest entry for 'images/favicon.png'问题2:500错误
确定存在静态图像处理错误后,我进行了搜索,并建议有人运行:
python manage.py collectstatic
我这样做了,但是仍然发现错误。接下来的事情是确保Whitenoise被注释掉:
#STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
但是,这导致了错误:
2018-09-13T13:13:49.905187+00:00 app[web.1]: "When using Django Compressor together with staticfiles, " 2018-09-13T13:13:49.905190+00:00 app[web.1]: ImproperlyConfigured: When using Django Compressor together with staticfiles, please add 'compressor.finders.CompressorFinder' to the STATICFILES_FINDERS setting.
我试图添加compressor.finders.CompressorFinder,但这给了我与上面类似的错误。所以我忽略了这一点。经过一番搜索,我发现我必须通过将其添加到settings.py中来基本禁用压缩器(至少据我所知):
COMPRESS_ENABLED = os.environ.get('COMPRESS_ENABLED', False)
这并不能完全解决问题,因为那时我在查找静态文件时遇到了问题。因此,我必须将STATIC_ROOT设置为此:
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
推送到heroku,就可以使用它... Debug = False现在可以工作了
