After_create callback in subclass

Rails
1

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.
