Rails - Jun 2005 - auto generating a login instead of using signup

Hi All,

 I''m using the generic salted login generator in my app to create user
accounts. I also have a model/controller called staffmember.
 What I would like to do is when an administrator creates a new
staffmember, I would like my app to autogenerate a new Account and
login (using a generic password which will have to be changed)

 For the life of me I can''t seem to get this to work - my (admittedly
bad) logic so far looks roughly like:

 (in Staffmember controller)
 def create
        @staffmember = Staffmember.new(@params[''staffmember''])
        if @staffmember.save
            #once new staffmember has been created...
            @newUser = User.new
             #do some magic here to call the signup method in the
account model or some such...
            redirect_to :action => ''list''
        else
            render_action ''new''
        end
    end
