我正在使用带有活动记录和 sqlserver 的 rails 3.2。我对嵌套表单有疑问。我有一个模型注册，其中包含许多注册详细信息，并且每个都有关联的人。

这是模型

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

        <span class="help-inline"><%=f.object.errors[:CCIUDADRESIDENCIA].join(", ")%></span>
        <% end %>
    </div>
</div>

最后是控制器

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

怎么了？首先，不会保存任何字段的更改，也不会显示验证。当我提交表单时，它返回到同一页面，并且似乎表单有错误但没有显示，并且数据丢失了。

希望您能够帮助我。

好吧，我不知道为什么，但我使用资源解决了。

在我的 routes.rb 文件中

resources :registrations

在我有这样的事情之前。

  match 'registration/(:event_date)/(:event_id)' => 'registration#index'
  match 'registration/save' => 'registration#save'

我认为问题出在我的自定义路线上。但我真的不知道。
