This is what I am using in one of my projects. It should't be problem to
make it in erb.
--------------------------------
def iframe_helper(if_name)
opts = { controller: 'somectrl', action: 'index', id: @record.id,
iframe: "if_#{if_name}" }
html = "<iframe class='iframe_embedded' id='if_#{if_name}'
name='if_#{if_name}'></iframe>"
html << <<EOJS
<script type="text/javascript">
$(document).ready( function() {
$('#if_#{if_name}').attr('src', '#{url_for(opts)}');
});
</script>
EOJS
html.html_safe
end
----------------------------------
In short:
opts = Hash to make url to display in frame.
iframe html code. if_name=name of iframe.
javascript part which loads iframe code by calling url when document is
loaded. You need jquery for all this to work.
