TextMate Snippet For Load_model Methods In Rails Controllers

        With nested routes, I find I create a lot of controller methods like:

def load_user
  @user = User.find(params[:user_id]) if params[:user_id]

Here's a TextMate snippet, so you can just type: defmodel, TAB, user, TAB, and you're done.

Snippet:
def load_${1:model}
	@$1 = ${1/[[:alpha:]]+|(_)/(?1::\u$0)/g}.find(params[${2::$1_}id])${3: if params[:$1_id]}
end

Activation: defmodel
Scope: source.ruby.rails 

I have this in the Ruby on Rails bundle, but you can put it anywhere. Its the scope that is important.
