Add image to layout in ruby on rails

Question

I would like to add an image in my template for my ruby on rails project where i currenly have the code <img src="../../../public/images/rss.jpg" alt="rss feed" /> in a the layout stores.html.erb file however this doesn't seem to load as it looks like its missing a route which i'm not sure what its supposed to be.

Any ideas please?

Answer 1

Anything in the public folder is accessible at the root path (/) so change your img tag to read:

<img src="/images/rss.jpg" alt="rss feed" />

If you wanted to use a rails tag, use this:

<%= image_tag("rss.jpg", :alt => "rss feed") %>

Answer 2

In a Ruby on Rails project by default the root of the HTML source for the server is the public directory. So your link would be:

<img src="images/rss.jpg" alt="rss feed" />

But it is best practice in a Rails project to use the built in helper:

<%= image_tag("rss.jpg", :alt => "rss feed") %>

That will create the correct image link plus if you ever add assert servers, etc it will work with those.
