Given an application layout like

 Test \<%= stylesheet\_link\_tag 'test.css' %\>

```
<%= javascript_include_tag 'some_js', :cache => true, :charset =>

```

‘utf8’ %\>

 \<%= yield %\> 

and a controller, say

app/controllers/root\_controller.rb:  
class RootController \< ApplicationController  
def index

end  
end

and a view file  
app/views/root/index.html.erb

is it then possible to include a javascript file in the head section  
of the resulting html, which is exclusive to the RootController’s  
index view?

Forgive me if you find this question trivial. I’m learning.
