Help with issue inserting associated field

[Tomás Rinke]

Hello, this is my first project with ror and netzke. I have two models Person and Interaction (one person can have many interactions) for a social worker office. 

i managed to show person last name in Interaction grid but when i click apply the id doesn´t persist, eventhough i see it noticed the change, but it cannot relate it to the person_id. I thought it would be kinda automatic. perhaps i´m breaking some convention. 

log:

Processing by NetzkeController#direct as HTML

  Parameters: {"path"=>"person_tab_panel__interactions", "endpoint"=>"postData", "data"=>[{"args"=>{"updated_records"=>"[{\"person__apellido\":2,\"id\":1}]", "base_params"=>"{}"}, "configs"=>[{"id"=>"person_tab_panel"}, {"id"=>"person_tab_panel__interactions"}]}], "tid"=>5, "authenticity_token"=>"eO8W5UpWgbbORsfzFycXgG85OxSiZqFJcOZgZkkrZU4=", "netzke"=>{"path"=>"person_tab_panel__interactions", "endpoint"=>"postData", "data"=>[{"args"=>{"updated_records"=>"[{\"person__apellido\":2,\"id\":1}]", "base_params"=>"{}"}, "configs"=>[{"id"=>"person_tab_panel"}, {"id"=>"person_tab_panel__interactions"}]}], "tid"=>5}}

  Interaction Load (1.5ms)  SELECT "interactions".* FROM "interactions" WHERE "interactions"."id" = 1 LIMIT 1

   (0.1ms)  begin transaction

   (0.1ms)  commit transaction

Components:

class Interactions < Netzke::Basepack::Grid

  def configure(c)

    super

    c.model = "Interaction"

    c.persistence = true

    c.columns = [

        { id:  :person__apellido, name: :person__apellido, header: 'Persona'},

        :voluntario

    ]

  end

end

Models: 

class Person < ActiveRecord::Base

  has_many :interactions

  attr_accessible :apellido, :documentoar, :documentoextra, :domicilio, :fecha_nac, :nombre, :sector, :telefono1, :telefono2

  validates_presence_of :documentoar

  def name

    "#{apellido}, #{nombre}"

  end

end

class Interaction < ActiveRecord::Base

   belongs_to :person

   attr_accessible :fecha_seguimiento, :propuesta, :situacion, :tipo, :voluntario

end

i´ve been playing a lot with this and could not figure it out...

my setup is: 

ruby 1.9.3p545

Rails 3.2.8.rc1

netzke-basepack (0.8.4)

netzke-core (0.8.4)

any clues?

thanks in advance

re did the models, and put only belongs_to, and worked fine. 

Thanks!
