Devise: creating extra records on user creation - ruby-on-rails

Question

How do I create extra records when a user creates an account with devise?
Using a HABTM association between a User and Team model, I'm trying create a team that the user is associated with on there account creation.
Below is the code that I have attempted to use.
class RegistrationsController < Devise::RegistrationsController
def create
super
current_user.teams.create(:name => 'User Name')
end
end
I have also tried this
class RegistrationsController < Devise::RegistrationsController
def create
build_resource
if resource.save
resource.teams.create(:name => 'User Name')
if resource.active_for_authentication?
set_flash_message :notice, :signed_up if is_navigational_format?
sign_in(resource_name, resource)
respond_with resource, :location => after_sign_up_path_for(resource)
else
set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
expire_session_data_after_sign_in!
respond_with resource, :location => after_inactive_sign_up_path_for(resource)
end
else
clean_up_passwords resource
respond_with resource
end
end
end

Answer 1

I solved this by changing routes.rb to point to the customised controller.
routes.rb
devise_for :users,
:controllers => { :registrations => "registrations" }
registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
def create
super
resource.teams.create(:name => 'User Name')
end
end

You can use a before_save in your model like this :
class User < ActiveRecord::Base
# ... your code ...
after_create :set_user_on_team
# ... your code ...
private
def set_user_on_team
teams.create(:name => username)
end
end
