Nested model form problem, not saving, any help?

Rails
1

I have two models, Curso and Ementa

class Curso < ActiveRecord::Base

attr_accessible :nome, :descricao, :periodo_inscricao_inicio,

:periodo_inscricao_fim

has_one :ementa, :dependent => :destroy

has_many :turmas

has_many :publico_alvos

accepts_nested_attributes_for :ementa

end

class Ementa < ActiveRecord::Base

belongs_to :curso

end

One form for hadle both models

<% form_for @curso do |f| %>

<%= f.error_messages %>

<%= f.label :nome %>

<br/>

<%= f.text_field :nome %>


<%= f.label :descricao %>

<br/>

<%= f.text_area :descricao %>


<%= f.label :periodo_inscricao_inicio %>

<br/>

<%= f.date_select :periodo_inscricao_inicio %>


<% fields_for :ementa do |ementa_form| %>

<%= ementa_form.label :descricao, “Ementa” %>

<%= ementa_form.text_field :descricao %>

<% end %>

<%= f.label :periodo_inscricao_fim %>

<br/>

<%= f.date_select :periodo_inscricao_fim %>


<%= f.submit "Submit" %>

<% end %>

the controller

class CursosController < ApplicationController

def index

@cursos = Curso.all

end

def show

@curso = Curso.find(params[:id])

respond_to do |format|

  format.html {render :layout=>false}

end

end

def new

@curso = Curso.new

@curso.build_ementa

respond_to do |format|

  format.html {render :layout=>false}

end

end

def create

@curso = Curso.new(params[:curso])

if @curso.save

  flash[:notice] = "Successfully created curso."

  redirect_to @curso

else

  render :action => 'new'

end

end

def edit

@curso = Curso.find(params[:id])

respond_to do |format|

  format.html {render :layout=>false}

end

end

def update

@curso = Curso.find(params[:id])

if @curso.update_attributes(params[:curso])

  flash[:notice] = "Successfully updated curso."

  redirect_to @curso

else

  render :action => 'edit'

end

end

def destroy

@curso = Curso.find(params[:id])

@curso.destroy

flash[:notice] = "Successfully destroyed curso."

redirect_to cursos_url

end

end

The result is just one insert on curso table, why it is not inserting on
ementa table to the “descricao” field?

Console result:
