Question

Is there a way for me to add a separate background image for a specific post on my rails app?

In my rails app I have different mixtapes, and I would like to add a custom background image for some of the mixtapes “show” view (not for every mixtape though).

I would upload the images myself.

Is there a gem or a tutorial that shows me how to accomplish this? Thanks in advance.

There are different ways how to do it, and the easiest one (in my opinion) is to define a CSS selector that is responsible for that and to set it from your Rails application.

Something like the following pseudo-code:

%div{:class => @post.bg_class}

Then your application.css file should include something like:

div.img1 {
    background-image:url(img1.gif);
}
div.img2 {
    ...
}

Or you could style your div directly with the necessary style (not tested this one):

%div{:style => "background-image: #{@post.bg_image};"}

But the difficult part is to find for each different post a background image …
