ValueError：缺少“ favicon.png”的静态文件清单条目

标签： django heroku static whitenoise

我正在尝试将django Web应用程序第一次部署到heroku，但是我仍然收到500个服务器错误。

这是我查看日志时看到的：

在我看来，问题是这个ValueError: Missing staticfiles manifest entry for 'favicon.png' 但是我在唯一引用favicon.png的模板中将其注释掉。我想知道settings.py文件中是否有问题。我在这方面很新，我正在使用whitenoise加载我的静态文件。也许我搞砸了一些路径：

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/3.0/howto/static-files/

STATIC_URL = '/static/'
MEDIA_URL = '/media/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static_in_env')]
VENV_PATH = os.path.dirname(BASE_DIR)
STATIC_ROOT = os.path.join(VENV_PATH, 'static_root')
MEDIA_ROOT = os.path.join(VENV_PATH, 'media_root')

#  Add configuration for static files storage using whitenoise
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

MIDDLEWARE = [
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.middleware.security.SecurityMiddleware',
    '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',
]

关于我在哪里出问题的任何想法吗？

1 个答案:

答案 0 :(得分：2)

我明白为什么这会造成一些混乱，但是就Django而言，您实际上并没有将其注释掉：

    <!-- <link rel="shortcut icon" href="{% static 'favicon.png' %}"> -->

您已在其中添加了HTML注释，这意味着浏览器将不再显示它，但是Django仍将在HTML中生成该行，因此它仍必须处理static指令。

如果您使用如下所示的Django template comments，它将起作用：

    {# <link rel="shortcut icon" href="{% static 'favicon.png' %}"> #}

在部署第一个站点时，如果暂时在设置中对此行进行注释，则可能会更容易：

#  Add configuration for static files storage using whitenoise
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

此设置有助于提高网站的性能，但是这意味着对丢失的静态文件的任何引用都将引发错误。首先，如果没有此功能，则可以更轻松地启动并运行您的网站，然后在确定其他所有功能都可以正常工作时，随后再启用它。
