Nested form does not validate association model - ruby-on-rails

Question

I'm using rails 3.2 with active record and sqlserver. I have a problem with nested forms. I have a model registration which has many registration details and each has a person associated.
Here is the model
class Registration < ActiveRecord::Base
set_table_name "dbo.EV_INSCRIPCIONES"
set_primary_key "Id"
belongs_to :category, :foreign_key => 'CategoriaId'
has_many :registrationDetails, :foreign_key => 'InscripcionEventoId'
#has_one :group
accepts_nested_attributes_for :registrationDetails
validates_associated :registrationDetails
validates :Refencia, :presence => true
#validates_presence_of :category_id
attr_accessible :registrationDetails, :category, :Eliminada, :FechaInscripcion, :CreationalDate, :Referencia, :PagoRegistrado, :Acreditado, :registrationDetails_attributes
#after_initialize :init
def init
write_attribute :Eliminada, false
write_attribute :Acreditado, false
write_attribute :PagoRegistrado, false
write_attribute :CreationalDate, DateTime.now
write_attribute :FechaInscripcion, DateTime.now
#write_attribute :Referencia, ''
end
def category_id
self.category.id unless category.nil?
end
def category_id=(id)
self.category = Category.find(id)
end
end
class RegistrationDetail < ActiveRecord::Base
set_table_name "dbo.EV_INSCRIPCION_DETALLE"
set_primary_key "Id"
belongs_to :registration, :foreign_key => 'InscripcionEventoId'
belongs_to :category, :foreign_key => 'CategoriaId'
belongs_to :person, :foreign_key => 'ParticipanteId', :primary_key => 'JUGADOR_ID'
attr_accessible :person, :category, :registration, :Eliminada, :person_attributes
accepts_nested_attributes_for :person
validates_associated :person
after_initialize :init
def init
write_attribute :Eliminada, false
end
end
class Person < ActiveRecord::Base
set_table_name "dbo.PKR_JUGADOR"
set_primary_key "JUGADOR_ID"
has_many :registrationDetails
validates_presence_of :CDNI, :CNOMBRES, :CAPELLIDO, :CSEXO,:CCIUDADRESIDENCIA, :DFECHANACIMIENTO
validates :CDNI, :length => { :minimum => 7, :maximum =>8 }
#validate :validate_birth_date
before_save :set_ids
def set_ids
if id.nil?
_id = Person.maximum(:JUGADOR_ID)
self.JUGADOR_ID = _id +1
write_attribute :CNROJUGADOR, _id+1
end
end
after_initialize :init
def init
write_attribute :TIPODOCUMENTO_ID, 1 if read_attribute(:TIPODOCUMENTO_ID).nil?
end
def full_name
self.surname + ", " + self.name
end
protected
def validate_birth_date
errors.add(:birth_date, 'must be a valid datetime') if ((Date.strptime(birth_date, "%d/%m/%Y") rescue ArgumentError) == ArgumentError)
end
end
My view
index.html.erb

And finally the controller
class RegistrationController < ApplicationController
def index
date = "20120729"
id = 1
#id = params[:event_id] unless params[:event_id].nil?
#date = params[:event_date] unless params[:event_date].nil?
#event = Event.find(date,id)
#groups = Group.all
#categorias = Category.where("DiaActividad = ? and TorneoId = ?", date, id)
#registration = Registration.new
#registration.registrationDetails.build( :person => Person.new)
end
def save
#registration = Registration.new(params[:registration])
if #registration.save
redirect_to :controller => 'home'
else
date = params[:event_date]
id = params[:event_id]
#event = Event.find(date,id)
#groups = Group.all
#categorias = Category.where("DiaActividad = ? and TorneoId = ?", date, id)
render :action => 'index'
end
end
end
What is happening? well first of all, the changes on any field are not saved, and the validations are not displayed. When i submit the form, it returns to the same page, and seems the form has errors but no one is displayed, and the data is lost.
Hope you can help me.
Thanks in advance

Answer 1

Well, I don´t Know why but I solved using resources.
In my routes.rb file
resources :registrations
Before I have something like this.
match 'registration/(:event_date)/(:event_id)' => 'registration#index'
match 'registration/save' => 'registration#save'
I think the problem was my custom routes. But i really don`t know.
