I have the following helper:
def feeder value=true
if feeder? == value
haml_tag :span, :<, :class => 'selected' do
yield
end
else
yield
end
end
And the following in a view:
- feeder(false) do
= link_to 'Leda', :root
This works as expected in haml non-ugly mode (development environment == haml indented code). However in production mode (e.g. haml ugly rendering) i get this html:
<h1>
<a href="/leda/">Leda</a>
<!-- THIS SHOULD NOT BE HERE >>> -->
<!DOCTYPE html>
<html>
<开发者_开发技巧head>
<meta charset='utf-8'>
<title>Feeder</title>
<meta name="csrf-param" content="authenticity_token"/>
<meta name="csrf-token" content="8kp4xt6ZJU2nL5uLgVBW6BcB/RTA75QwynKvZTMtNF8="/>
<link href="/leda/stylesheets/jquery-ui/smoothness/jquery-ui.css?1297978005" media="screen" rel="stylesheet" type="text/css" />
<link href="/leda/stylesheets/admin.css?1298951622" media="screen" rel="stylesheet" type="text/css" />
<script src="/leda/javascripts/jquery.js?1297978005" type="text/javascript"></script>
<script src="/leda/javascripts/jquery-ui.js?1297978004" type="text/javascript"></script>
<script src="/leda/javascripts/rails.js?1297978005" type="text/javascript"></script>
<script src="/leda/javascripts/application.js?1300153136" type="text/javascript"></script>
</head>
<body>
<div id='wrapper'>
<div id='header'>
<h1>
<a href="/leda/">Leda</a>
<!-- <<< END -->
»
<span class='selected'><a href="/leda/servers/GVM-S1">gvm1</a></span>
</h1>
Replacing the else clause with this:
else
haml_tag :span do
yield
end
end
fixes the problem, but i can't possibly understand why/how. What puzzles more is that it only fails on haml ugly rendering mode.
Why not just do it all in the view, like this?
%span{:class => blah.feeder? && "selected"}= link_to 'Blah', blah
(haml docs on this are right here.)
Your helper version seems unnecessarily complex.
