All of this actuall comes out right. The _problem_ is that ones it compiles
this the first go-round, in my application.haml layout
!!! Strict
%html
%head
%title= "Oyster" + subtitle
= javascript_include_tag :defaults
= stylesheet_link_tag("oyster").downcase
That stylesheet_link_tag("oyster").downcase returns a member of the @tags
array. There's a call to the Rails method tag in there somewhere and because
the page has been compiled that first time tag is still showing up from the
render :partial => "tag", :collection => @tags which [I assume] is basically
a @ tags.each do |tag| and I've seen where that tag from the loop can stay
in or out of "scope" oddly before.
Does that clear it up? [Clear as mud, right?]
