Ruby on Rails 显示带有 image_tag src 的图像

Question

I have an image in my app/assets/images folder and I'm in my view page trying to display an image.

<%= image_tag "NoAvatar.png" %>

When I load my page in localhost my image only shows /assets/ in its src path

<img alt="Assets" src="/assets/">

I'm not understanding why this is the issue? Am I doing something wrong? I thought this was how its supposed to link to an image in your pipeline?

Thanks!

Answer 1

rails 3.1 n later have a new feature called 'asset pipeline', u can read it at http://guides.rubyonrails.org/asset_pipeline.html

u can access the image in the view as

= image_tag "/assets/large/icon.png"

the image 'icon.png' resides in 'large' under 'images' in 'assets'

to see how to refer the same image in css, see Rails 3.1 and Image Assets

如果您的图像在资产中，请使用：

<%= image_tag("entretien.jpg", width: 200) %>
