Awesome! The only thing more fun than writing code is deleting code.

Re: using ActiveRecord::Validations::ClassMethods
params is simply Rails' version of @input.
If you name your keys "user[id]" and "user[name]" in the HTML, then
@input.user should contain a Hash like { 'id' => ..., 'name' => ... } (maybe
the keys are Symbols; I don't remember at the moment)

Hah, yeah, the bracket is missing.
