预编译上传的资产 [英] Precompiling uploaded assets

问题描述

我有一个用户上传图片的rails 3.1应用程序。我将它们存储在/ assets / images中，因为这是image_tag寻找的路径，而不是public / images。

在开发中一切正常，但我部署到Heroku和它给我这个错误：

ActionView :: Template :: Error（image_name.jpeg未预编译）

处理这种情况的正确方法是什么？有没有办法在上传后编译图像，或者我应该将它们存储在其他地方？ p>您不得在Heroku上使用文件系统来存储上传内容。 与上传的图像，因为它假定它正在看文件系统。如果您使用 image_tag ，则必须传递完整的网址，而不仅仅是图片名称。 b

I have a rails 3.1 application where users upload pictures. I am storing them in /assets/images since that is the path image_tag looks for instead of public/images.

Everything works fine in development but I deployed to Heroku and it gives me this error:

ActionView::Template::Error (image_name.jpeg isn't precompiled)

What is the right way to handle such a situation? Is there a way to compile images after uploading or should I store them somewhere else?

解决方案

• You must not use the filesystem on Heroku to store uploads.

• You should not use image_path with uploaded images, since that assumes it is looking at the filesystem. If you use image_tag, you must pass a complete URL, not just an image name.
