将 Django 应用程序部署到 Heroku 无法加载静态文件

Question

我已成功将我的 django 应用部署到 heroku。但由于某种原因，他们无法加载模板和静态文件。

我的目录是这样的： eximia（项目目录）

• eximia：init.py asgi.py settings.py wsgi.pyurls.py
• web：模板，静态：web：style.css，图片：（所有图片都在这个文件夹中）

其余文件都是普通的典型django应用文件。

我的settings.py如下：

Django settings for eximia project.

Generated by 'django-admin startproject' using Django 3.1.

我对 django 很陌生，这是我的第一个网站。因此，如果有任何帮助，我将不胜感激！谢谢！ :D

Answer 1

要在 Heroku 中提供静态文件，您必须使用 Whitenoise。 如果您不知道如何使用，请查看 Heroku 文档Here

Answer 2

我认为您有一个不与任何特定应用绑定的全局 static 文件夹。
如果您在每个应用程序中都有静态文件夹，那么 django 收集静态文件并将它们放入 staticfiles 不会有问题，但在您的情况下，您需要告诉 django 存在全局 static 与特定应用无关的文件夹以从中收集静态文件：

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