Rails - Sep 2007 - Better render_if_exists

Hello,

I''m building a little polymorphic page (I mean that you use the same
page to deal with objects coming from different models, for instance
users and products) and I need to render some partial templates if they
exist, and get no error if they don''t (for instance I''ve got a
partial
template called _optional_fields_user which I''d like to load, but
_optional_fields_product doesn''t exist and I''d like to use the
same code
to load both.

So I build a little helper :

def render_if_exists toRender
  begin
    render toRender
  rescue  ActionView::ActionViewError
  end
end

and I call it :

<%=render_if_exists :partial
=>"optional_fields_#{@element.className}"%>

Everything works fine but I think it''s ugly to do it this way, would
anyone have anything better?

Thanks
