部署到heroku后無法在Django中加載照片

我使用 Django 創建了一個投資組合 博客網站。它在本地運行時運行良好，但在我將它部署到 Heroku 后，訪問投資組合將我重定向到 500 服務器錯誤。我打開除錯模式，當我做同樣的事情時，它沒有拋出 500 服務器錯誤，但是，圖片不會加載。這非常令人困惑，將非常感謝您的幫助......

編輯：將 DEBUG_PROPAGATE_EXCEPTIONS 設定為 True 后，我在 Heroku 日志中收到此錯誤 ValueError: Missing staticfiles manifest entry for 'staticfiles/project1.png'

uj5u.com熱心網友回復：

您的settings.py看起來不錯，嘗試將此代碼添加到 project-name/urls.py

from django.conf import settings
from django.conf.urls.static import static

urlpatterns  = static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) # add static file URL to django urlpatterns

如果您嘗試托管媒體檔案，請注意 Heroku 不支持媒體托管，您可能需要將 Django 應用程式與類似 amazon s3 bucket 的內容連接起來。你可以在這里找到一篇關于它的文章。

如果這對您有用，請接受答案。快樂編碼！
