Hello everybody i'm new working with rails.

I want to creata new relation in my app but it fail. This is the code:

model profile.rb

class Profile < ActiveRecord::Base

  has_many :responsibles

end

model reponsible.rb class Responsible < ActiveRecord::Base

  belongs_to :profile, :class_name => 'Profile', :foreign_key => 'profile_id'

end

in the controller responsibles_controller.rb

class Member::ResponsiblesController < Member::BaseController

  def create     @responsibles = current_user.responsibles.build(params[:responsible].values)     @responsible.save!

    flash[:ok] = I18n.t("tog_picto.member.responsibles_created")     redirect_to profile_path(profile)   end

  def update     responsible.update_attributes!(params[:responsibles])     responsible.save     flash[:ok] = I18n.t("tog_social.profiles.member.responsibles_created")     redirect_to profile_path(profile)   end

end

and in the view to edit the profile i want to add if it's possible update the responsibles:

<%= error_messages_for :profile %>

  <% form_for :profile, :url => member_profile_path(@profile), :html => {:method => :put, :multipart=>true} do |f| -%>     <fieldset>       <legend><%= I18n.t('tog_social.profiles.member.profile_details') %></legend>       <div class="fields">         <!--Nombre del perfil-->         <p>           <label for="profile_first_name"><%= I18n.t('tog_social.profiles.model.first_name') %></label>           <%= f.text_field :first_name, :class=>"fieldbox" %>         </p>       <!--Apellidos del perfil-->         <p>           <label for="profile_last_name"><%= I18n.t('tog_social.profiles.model.last_name') %></label>           <%= f.text_field :last_name, :class=>"fieldbox" %>         </p>

What you want to use is :accept_nested_attributes in your models

class Profile < ActiveRecord::Base

  has_many :responsibles   accepts_nested_attributes :responsibles

end

And then you'll want to do something like this in your view

<% form_for @profile do |profile_form| %>

  <%= profile_form.label :name %>   <%= profile_form.text_field :name %>

  <% profile_form.fields_for :responsibles do |child_form| %>

    <%= child_form.label :name %>     <%= child_form.text_field :name %>

    <% unless child_form.object.new_record? %>       <%= child_form.check_box '_delete' %>       <%= child_form.label '_delete', 'Remove' %>     <% end %>

  <% end %>

  <%= submit_tag %> <% end %>

That's all

In order to use this, you have to ensure you're using rails 2 but I'm sure you are.
