After checking out Rails v2.1.0\_RC1 this is broken:

@filters = Filter.find(:all)

undefined method `find’ for ActionController::Filters::Filter:Class

It works fine in the console but breaks in the view… any ideas?

Use ::Filter

There is an internatl ActionController class called filter, when ruby  
sees Filter inside a controller it’s search algorithm dictates that  
the one it finds is the ActionController one. ::Filter means ‘start at  
the top level’ and so it will find your class.
