Why is Rails adding 'localhost:3000/assets' to my image src?

Question

I'm looping over a collection of Movies in my movie like so:

<li>
  <%= link_to image_tag(movie.image.url), movie %>
  <%= link_to sanitize(movie.title), movie %>
</li>

But it's generating the following html:

<img alt="3382" src="http://0.0.0.0:3000/assets/http//s3-eu-west-1.amazonaws.com/ramen-hut/pictures/3382.jpg?1344477777">

It's baffled me, could anyone help on this? WHy is it adding that http://0.0.0.0:3000/assets/ url?

Answer 1

Because : is missing after http in your movie.image.url.

Without http://, Rails thinks this is an asset name and adds the asset prefix.

For example:

<%= image_tag 'http//foo/bar.jpg' %>
<%= image_tag 'http://foo/bar.jpg' %>

Outputs:

<img alt="Bar" src="/assets/http//foo/bar.jpg" />
<img alt="Bar" src="http://foo/bar.jpg" />
