Rails - May 2006 - label tag with errors?

I''d like to create a label tag that has a special css class if has
errors.
So Ideally, I''d like:

<%=
label(''object'',''property'',''Property'')
%>

To generate:

<label for="object_property">Property</label>

And if there are errors on object.property, generate this:

<label for="object_property"
class="fieldWithErrors">Property</label>

First of all, is there an easy way to do this?

I''m assuming there isn''t, so I thought it shouldn''t
be too hard to create my
own helped to do this, but after taking a look at the source for the other
tags (text_field, check_box, etc.), it''s not clear how to do it.  Any
ideas?

Paul,

You can do this by creating a custom form builder.  Do some research on that. 
Here is a place to start:
