SQL request problem

[jsaray]

Hi, I am using your gem, I have the following class structure
MIGRATIONS ==============================
class CreatePeople < ActiveRecord::Migration
def self.up
create_table :people do |t|
t.string :personible_type
t.integer :personible_id
t.string :name, null: false
t.string :email, null: false
t.string :phone
t.string :picturepath
t.timestamps
end
end
end

class CreateGuides < ActiveRecord::Migration
def self.up
create_table :guides do |t|
t.integer :person_id
t.integer :price, null: false
t.integer :reputation
t.timestamps
end
add_foreign_key :guides,:people
end
end

MODELS=======================
class Person < ActiveRecord::Base
acts_as_superclass
end
class Guide < ActiveRecord::Base
acts_as :person, :as => :personible
has_many :availabilities
end
In Guides controller, I have the following statement
result = Guide .where("name = ?",name)

This query gives the following console output :

SELECT guides.id AS t0_r0, guides.person_id AS t0_r1, guides.price AS t0_r2, guides.reputation AS t0_r3, guides.created_at AS t0_r4, guides.updated_at AS t0_r5, people.id AS t1_r0, people.personible_type AS t1_r1, people.personible_id AS t1_r2, people.name AS t1_r3, people.email AS t1_r4, people.phone AS t1_r7, people.picturepath AS t1_r8, people.created_at AS t1_r9, people.updated_at AS t1_r10 FROM guides INNER JOIN people ON people.personible_id = guides.id AND people.personible_type = 'Guide' WHERE (name = 'Jhon')

So the SQL statement is ok. however in the object retrieved in the controller I get :

[{"id":1,"person_id":null,"price":40,"reputation":null,"created_at":"2014-08-23T08:09:06.000Z","updated_at":"2014-08-23T08:09:06.000Z"},{"id":2,"person_id":null,"price":321,"reputation":null,"created_at":"2014-08-23T12:28:38.000Z","updated_at":"2014-08-23T12:28:38.000Z"}]

As you can see the person parameters (name,email,phone etc) are not being retrieved.

Any clues ?.
