Django Site Can't Find Admin Styling or Media Files when Debug = False

 原文  2020-02-27 16:07:06  8   1    python/ django/ wagtail

Question

I'm having trouble getting my django site running with debug = False.

Info:

  • Currently, Debug = False
  • I am running on my local host
  • I'm using Wagtail. But from what I've read, the problems I'm dealing with are more Django-related.

Problem:

  • When I go to the site on my local host, it can find static files, but it can't get any 'media' files.Example: GET http://127.0.0.1:8000/media/images/block-alphabet-abc.width-400.png Internal Server Error

  • When I log into the admin panel, the look and feel is off in some places (like css components may be missing).

  • When I go to edit a page, the look and feel is still off and the web developer tool has a bunch of 500 errors saying things like the http://127.0.0.1:8000/static/wagtailadmin/js/date-time-chooser.js?v=3a1ab45f is missing.

What I have tried:

  • I have ran python manage.py collectstatic . Doing that does not create the media directory though. It adds the wagtail admin files, but none of them have the little hash at the end.
  • I tried running python manage.py compress, but I keep getting the error that none of the templates have the compression tag (which is true).
  • I added logging, but I'm not sure how to resolve the errors.

Question:
How do I create the media directory? How do I get the wagtail admin files added in the right format so they can be found?

STATIC & MEDIA URLs in settings.py 

# Static files (CSS, JavaScript, Images)

STATICFILES_FINDERS = [
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
]

STATICFILES_DIRS = [
    os.path.join(PROJECT_DIR, 'static'),
]

# ManifestStaticFilesStorage is recommended in production, to prevent outdated
# Javascript / CSS assets being served from cache (e.g. after a Wagtail upgrade).
STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.StaticFilesStorage'

STATIC_ROOT = "/var/www/html/static/"
STATIC_URL = '/static/'

MEDIA_ROOT = "/var/www/html/media/"
MEDIA_URL = '/media/'

Top of the Base.html Template that use STATIC_URL:

{% load static wagtailuserbar %}
{% load wagtailcore_tags %}
{% load wagtailcore_tags site_tags %}
{% load wagtailcore_tags wagtailimages_tags %}

    {% get_global_settings request=request as global_settings %}
    {% if global_settings.site_logo %} 
        {% image global_settings.site_logo width-2000 as site_logo %}
        <link rel="icon" href="{{ site_logo.url }}" type="image/png" sizes="16x16">
    {% endif %}

        {# Global stylesheets #}
        <link rel="stylesheet" type="text/css" href="{% static 'css/sitename.css' %}">

        {% block extra_css %}
        {# Override this in templates to add extra stylesheets #}
        {% endblock %}

    </head>

Django's runserver is not to be used in production. By setting DEBUG to True , you are now running in a production-like environment. runserver won't serve media files , so if you want to mimic a server-style setup on a dev machine, what you should do is install a production-type server such as Apache and set it up to serve media files as you normally would with the proper alias. You would also need to create an alias for static files.
