Rails Building an Object that has a Parent? – ruby-on-rails, ruby-on-rails-3

I have the following two models in my app Spaces which are like projects & Permissions

class Space < ActiveRecord::Base
 has_many :permissions
 has_many :users, :through => :permissions

class Permission < ActiveRecord::Base
  belongs_to :user 
  belongs_to :space
  belongs_to :role
  validates_presence_of :space_id , :user_id, :role_id

So here’s what I’d like to do, in the Space Controller, when the user does DEF CREATE, I want to create a space, and a permission with role_id = 1, to ensure the space/project as the creator as a member…

Here’s what I have. It’s getting messy and not creating the permission

Space Controller:

def create
  @space =[:space].merge(:creator => => 1, :user_id =>
  respond_to do |format|

Thanks for your help
