ruby-on-rails-3.2 - Rails 3.2 访问公共镜像

Question

我在 Rails 3.2 上，我的图像im.png位于app/assets/images. 如何在我的网站上访问它？我试过app/assets/images/im.pngand im.png，但都不管用。

Answer 1

Use the image_tag helper:

<%= image_tag('im.png') %>

Which will generate a URL like:

/assets/im.png

Which is a "virtual" URL and doesn't exist on disk - but the asset pipeline will serve it from app/assets/images/im.png where it does in fact reside on disk.

Answer 2

<%= image_tag("im.png") %>

返回图像的 HTML 标记：

<img src="/assets/im.png" />

你可以使用任何一个，你会得到相同的结果。
