Rails - Jun 2008 - after_create callback in subclass

I have a User model with a protected method defined:

  def set_role(rolename)
    role = Role.find_by_rolename(rolename)
    permission = Permission.new
    permission.role = role
    permission.user = self
    permission.save(false)
  end

and a subclass with:

  after_create set_role(''client'')

This always fails for me with the error:

  undefined method `set_role'' for #<Class:0x2798838>

however, if I call it with a symbol:

  after_create :set_role

it finds the method, but fails with a "wrong number of arguments" (as
you would expect).

How can I call the method as a symbol and pass arguments at the same
time?

thanks

ok, I just reread the activerecord docs and found the answe:

''The callback macros usually accept a symbol for the method they‘re
supposed to run, but you can also pass a "method string", which will
then be evaluated within the binding of the callback''

So I used after_create ''self.set_role("client")'' and
it worked fine.
