我正在尝试使用 Docker、django-pipeline 和 whitenoise 在 Heroku 上部署 Django 项目。容器构建成功,我看到 collectstaticcontainer-name/static 中生成了预期的文件。但是,在访问任何页面时,我都会收到以下 500 错误:

ValueError: Missing staticfiles manifest entry for 'pages/images/favicons/apple-touch-icon-57x57.png'

下面是我的 settings.pyDockerfileheroku.yml。因为我也在使用 django-pipeline,所以我不确定要为 STATICFILES_STORAGE 使用什么设置?我试过了

STATICFILES_STORAGE = 'pipeline.storage.PipelineStorage'

但这会导致文件路径 404ing。

欢迎任何建议。谢谢。

更新

基于 ENDEESA 对 this similar SO post 的回复,我将我的设置更新为以下内容,因为我的静态文件存储在 pages/static/pages 中:

STATIC_URL = "/static/"
STATICFILES_DIRS = [str(BASE_DIR.joinpath("pages/static"))]
STATIC_ROOT = str(BASE_DIR.joinpath("static"))

我还注意到我的顶级 urls.py 文件包含以下行:

urlpatterns += staticfiles_urlpatterns()

据我了解,这对于在开发中提供静态文件很有用,但不应在生产中使用,因此我将其移动为仅在 DEBUG 为 True 时才添加。但遗憾的是,错误仍然存​​在。

更神秘的是,当我运行时

python manage.py findstatic <file-path> --verbosity 2

找到文件:

Found 'images/favicons/apple-touch-icon-57x57.png' here:
/code/pages/static/images/favicons/apple-touch-icon-57x57.png
/code/pages/static/images/favicons/apple-touch-icon-57x57.png
Looking in the following locations:
/code/pages/static
/code/static
/usr/local/lib/python3.8/site-packages/django/contrib/admin/static
/usr/local/lib/python3.8/site-packages/debug_toolbar/static
/usr/local/lib/python3.8/site-packages/django_extensions/static
/usr/local/lib/python3.8/site-packages/rest_framework/static

那么为什么我仍然收到 ValueError: Missing staticfiles manifest entry

最佳答案

已解决

最后,我得出了以下解决方案。我的主要问题是:

  • 静态文件似乎是在发布命令期间收集的,但实际的 STATIC_ROOT 目录在我的容器中是空的。我不确定为什么。我的解决方案是不在 heroku.yml 中将 collectstatic 作为发布命令运行,而是在 Dockerfile 中运行。
  • 注意:为了在我的 Dockerfile 中使用 collectstatic,我需要为所有环境变量设置默认值,包括 SECRET_KEY,后者用于这是我使用 django.core.management.utils 中的 get_random_secret_key() 完成的。谢谢Ryan Knight对于 illustrating this here .
  • 除了我的 settings.py 需要默认 key 外,我的最终静态文件设置如下所示。
  • 因为我使用的是 django-pipeline,所以我的 js 文件无法使用 whitenoise 存储选项正确加载。我最终改用了 pipeline.storage.PipelineStorage
  • 事实证明我根本不需要设置 STATICFILES_DIRS。以前我将其设置为:
STATICFILES_DIRS = [
str(BASE_DIR.joinpath("pages/static")),
str(BASE_DIR.joinpath("staticfiles")),]

两者都是不必要的,因为 app_name/static/app_namedefault place Django will look for static files已经,而且我实际上并没有在 root/staticfiles 中存储额外的非特定于应用程序的文件。所以我删除了这个设置。

  • heroku.yml 中,我删除了 collectstatic 的发布命令。
  • 在我的 Heroku 应用程序管理员的设置页面上,我为 DISABLE_COLLECTSTATIC 添加了一个配置变量,设置为 1
