Problem with has_many

[h0bit]

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| -%>

<%= I18n.t(‘tog_social.profiles.member.profile_details’)
%>

<%=
I18n.t(‘tog_social.profiles.model.first_name’) %>
<%= f.text_field :first_name, :class=>“fieldbox” %>

<%=
I18n.t(‘tog_social.profiles.model.last_name’) %>
<%= f.text_field :last_name, :class=>“fieldbox” %>

  <p>
    <label for="profile_situation"><%=

I18n.t(‘tog_social.profiles.model.situation’) %>


<%= I18n.t(“tog_social.profiles.model.select_situation”)
%>

  <p>
    <%= check_box_tag 'profile_demandante_de_empleo'%>
  <label for="profile_demandante_de_empleo">

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.

Thanks Luis

I did what you said me, but when I submit the form I see that the
field send well, but in the table of responsibles don’t appear the
responsibles, Could you tell me why? Is necessary to do something in
the profiles_controller?

I have the next code for your help:

<% form_for :profile, :url => member_profile_path(@profile), :html =>
{:method => :put, :multipart=>true} do |f| -%>

<%=
I18n.t(‘tog_social.profiles.member.profile_details’) %>

<%=
I18n.t(‘tog_social.profiles.model.pyme_name’) %>
<%= f.text_field :first_name, :class=>“fieldbox wide” %>

      <!--Tipo de empresa-->
      <p>
          <label for="profile_type_of_pyme"><%=

I18n.t(‘tog_social.profiles.model.type_of_pyme’) %>
