Django没有提供用户在heroku上传的媒体文件

我已经尝试了一切，但不知何故，我无法看到用户上传的图像。我在heroku上部署了代码，每个静态文件都正确加载。用户甚至会纠正图像的路径，但不知何故服务器显示没有找到图像的错误。Django没有提供用户在heroku上传的媒体文件

你做了python manage.py collectstatic吗？ – alejosocorro

@alejosocorro是的，我确实collectstatic。问题是用户上传的媒体文件。他们正在上传，但当我打开它们时，django发生错误，即使位置看起来正确 –

您无法在Heroku上本地保存用户上传的文件。文件系统是短暂的，并且不会在dyno重新启动或并发dynos之间持续存在。你需要把它们上传到更永久的地方;一个流行的选择是亚马逊S3，并且有很多图书馆可以为你做到这一点。

感谢Daniel，但我仍然应该看到图像，直到dyno运行 –

只有当您实际配置了某些服务/媒体/。 WhiteNoise大概用于提供静态资产，默认情况下仅在STATIC_URL中提供服务。 –
