I have this in app/views/layouts/application.html.slim

doctype html
html
  head
    = stylesheet_link_tag "application"
    = yield :stylesheet    
    = javascript_include_tag "application"
    = yield :javascript

  body
    = render 'gitkit'
    = yield

and this in app/views/application/_gitkit.html.slim

== content_for :javascript do
  = javascript_include_tag "https://ajax.googleapis.com/ajax/libs/googleapis/0.0.4/googleapis.min.js"

div id='gitkit'

Ideally, I should see = javascript_include_tag "https://ajax.googleapis.com/ajax/libs/googleapis/0.0.4/googleapis.min.js" where = yield :javascript is in my layout, but this does not happen. The div id='gitkit' part shows up but the contents of content_for :javascript are nowhere to be found.

<!DOCTYPE html> 
<html> 
  <head> 
    <link href="/assets/application.css" media="screen" rel="stylesheet" type="text/css" />
    <script src="/assets/application.js" type="text/javascript"></script>
  </head> 
  <body>
    <div id="gitkit"> </div> 
  </body>
</html>

I've tried using - content_for, = content_for, and == content_for, all to no avail.

I'm using Rails 3.1.0 with Slim 1.0.2

I think this is not possible if streaming is activated since the content of the layout is generated before the partials. Can you ask on a rails list please?

Please try if the issue is really streaming by turning streaming off:

Slim::Engine.set_default_options :streaming => false

I think I just confirmed the problem here. It looks like you can't capture view data from partials inside layouts, only templates.

Ok, seems that partials don't allow content_for.

@minad Is that a rails or a slim limitation?

I think this statement

partials don't allow content_for

is not true. content_for in partials works just fine.
It does however depend on the order in which the partials / templates are processed. More explanation here http://stackoverflow.com/questions/2026740/rails-using-content-for-after-the-corresponding-yield-inside-layout

Anyway, this is really not a SLIM issue.
