I am dabbling in some existing code and I am able to render some HAML like this:
.content_container
%strong{:class => "code", :id => "message"} Hello World!
But when the page loads, this HTML is rendered in an existing layout with a lot of the elements already defined.
I looked in config/settings/environment.rb which I was suggested to do by a HAML tutorial, but there was no mention of any other HAML code there.
Any idea how I can overwrite the header or find where the template is predefined?
It sounds like the template is being rendered with a layout. look in
<app_root>/app/views/layouts/for your missing HTML.
