Thanks for your response.
But isn't this a polymorphic association?. I'am trying to do exactly
that with a polymorphic association, that is, create the user table with
all the common information, and with meta_type:string (that saves the
type of user) and meta_id:integer (that saves the id of the user on his
type of user table), and implement the associations y the models after,
like this:
class User < ActiveRecord::Base
...
belongs_to :meta, :polymorphic => true
end

class Chef < ActiveRecord::Base
has_one :user, :as => :meta
...
end
(more models)

So , each register user will have an entry in the user table, and on his
user type table.
The problem is that i don't know to modify the Registration controller
of Devise to do that.
Regards!
