Plugins - error_messages_for clickable links
Add to favoritesWhen you call error_messages_for :model, each attribute name is clickable, taking you to the individual text box where it has issues.
Example:
[div class="errorExplanation" id="errorExplanation"]
[h2]2 errors prohibited this user from being saved[/h2]
[p]There were problems with the following fields:[/p]
[ul]
[li][a href="#user_password"]Password[/a] can't be blank[/li]
[li][a href="#user_email"]Email[/a] can't be blank[/li]
[/ul]
[/div]

I like the idea behind this plugin, but I fear the current implementation puts logic in the Model that should be in the View instead. You may very well want to use the ActiveRecord::Errors#fullmessages method for output other than HTML. For example, the Errors#toxml method uses the full_messages method too.
