在公共文件夹中显示静态图像(rails 4) [英] Display static image in public folder (rails 4)

问题描述

我在公共文件夹中有一些图像，我在控制器中获取了 url /public/link/to/image.jpg.我想在我的视图中显示它，所以我将 url 传递给视图.

I have some images in the public folder, I obtain the url /public/link/to/image.jpg in my controller. I want to display it in my view, so I passed the url to the view.

但是我怎样才能在网页上显示它呢?

But how can I display it on the webpage?

我搜索了帖子，大部分都与assets文件夹中存储的照片有关，可以通过<%= image_tag image-url (filename) %> in view 来检索.

I searched through the post, most of them related to photos stored in assets folder, whichi can be retrieved by <%= image_tag image-url (filename) %> in view.

那么我怎样才能在视图中显示公共文件夹中的图像?

So how could I display image in public folder in view?

我以前从未通过公共文件夹完成过，但如果我不得不猜测，我会说您不需要文件路径的/public"部分.

I've never done it through the public folder before, but if I had to guess I'd say you don't need the "/public" part of the file path.

如果我理解了这个问题，那就应该这样做 - 希望有所帮助.

If I understand the question, that should do it - hope to have helped.
