Django:Whitenoise无法在生产环境中使用debug false [英] Django: Whitenoise not working in production with debug false

问题描述

我有一个带有whitenoise的Django应用，用于处理静态文件.但是，当我使用Google Lighthouse测试该应用程序时，系统会要求我为我的静态.js和.css文件启用文本压缩.

I have a Django app with whitenoise for static files. But when I test the app with Google Lighthouse I get asked to enable text compression for my static .js and .css files.

我阅读了很多相关文章，但找不到答案.

I read a lot of related posts but couldn´t find an answer.

我还按照Heroku的指南进行了实施. https://devcenter.heroku.com/articles/django-assets

I also followed Heroku´s guide to implement it. https://devcenter.heroku.com/articles/django-assets

设置

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django_user_agents.middleware.UserAgentMiddleware',
]

STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATIC_URL = '/static/'
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

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

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

我也将Dropbox用于媒体文件，但这似乎不是问题，我将其删除，但仍然存在静态文件问题.

I also use Dropbox for media files, but it seems not to be a problem, I i remove it I still have the static files problem.

DEFAULT_FILE_STORAGE = 'storages.backends.dropbox.DropBoxStorage'

要求

我确实将最新的Whitenoise包含在要求中，并且在部署Heroku时不会出错:

I do have the latest Whitenoise included in the requirements and while deploying Heroku gives no error:

whitenoise==4.1.2

在Lighthouse中测试时，要求压缩此文件.它们来自静态"文件夹，我知道在运行Manage.py collectstatic时应该对其进行压缩

When testing in Lighthouse, this files are requested to be compressed. They come from the Static folder and I understand they should be compressed when I run Manage.py collectstatic

…css/bootstrap.min.css(afternoon-wildwood-39943.herokuapp.com)
…js/jquery-3.2.1.min.js(afternoon-wildwood-39943.herokuapp.com)
…js/bootstrap-table.min.js(afternoon-wildwood-39943.herokuapp.com)
…css/Fran%20Style.css(afternoon-wildwood-39943.herokuapp.com)
…js/popper.min.js(afternoon-wildwood-39943.herokuapp.com)

调试设置

我读到也许应该将debug设置为False才能起作用.上面的示例是使用Debug = True完成的.

I read that maybe debug should be set to False to make it work. The example above was done with Debug = True.

DEBUG = bool(os.environ.get('DJANGO_DEBUG', True))

在这种情况下，该应用程序可以正常运行，但是如果将debug设置为False，则会出现500页错误.

The app works fine in this case, but if If turn debug to False, I get and error 500 page.

我在Heroku托管.您可以尝试以下示例: http://afternoon-wildwood-39943.herokuapp.com/网站/

I´m hosting in Heroku. You can try an example in: http://afternoon-wildwood-39943.herokuapp.com/website/

有任何线索吗?预先感谢！

Any clues? Thanks in advance!

推荐答案

感谢Heroku的支持，我为这个问题找到了解决方案.现在，我的应用程序可以正常运行，并且将debug设置为false，我可以得到whitenoise提供的Gzip静态文件.

Thanks to Heroku support I got a solution for this problem. Now my app works fine with debug set to false and I get the Gzip static files served by whitenoise.

Collectstatic

首先，您应该在将应用程序部署到Heroku之前运行collectstatic命令，我一直认为这是部署后要做的事情.

First you should run the collectstatic command BEFORE deploying the app to Heroku, I always thought that was something to do after deployment.

Procfile

在procfile中，您应该添加以下代码行:

In the procfile you should add the following line of code:

release: python manage.py migrate
