I have recently begun the practice of using <%# Ruby on Rails comments %> in my html.erb files, as these do not display in the source code that is then viewable by a user. Is there a way of adding comments to .css files that keeps them private from the eyes of devilish onlookers? ...
I know it's a bad practice to use database in the view. However, I'm also passing the User object and I wonder how I can make it easy to use. I love the way it works in Ruby On Rails.

So I'm trying to get a remove link next to the caption in an emails form. However, my rails voodoo is clearly very weak. It escapes the HTML and I can't figure out how to get it to not. Any hints? = f.input :email, :label => "Email " + link_to_remove_fields("[x]", f) [edit] oh and yes, this does the same thing: = f.input :email, :lab...

What I'd like your advice on is how/where the subnav logic should live in the...
