Problems using Globalize 2 crud with rails 2.3 nested attributes

Hi to all !

Seems that none can help me on ruby-i18n group..., I hope someone can help me...
:-(

I''ve try to make a crud sample application using Globalize2 and Rails
2.3.2 nested attributes.

All works great for edit/update operation but on new/create I cannot insert
record, seems that when I save :globalize_translations nested attributes there
is a ghost record without values and the validations stop the saving process.

Can someone can help me ? (MANY THANKS IN ADVANCE !!!)

Here the example to reproduce the problem:

Model: app/models/article.rb

class Article < ActiveRecord::Base
   translates :title, :text
   validates_presence_of :title
   accepts_nested_attributes_for :globalize_translations
end

Migration: db/migrate/20090207200522_create_articles.rb

class CreateArticles < ActiveRecord::Migration
   def self.up
     create_table :articles do |t|
       t.boolean :published
       t.timestamps
     end
     Article.create_translation_table! :title => :string, :text => :text
   end

   def self.down
     Article.drop_translation_table!
     drop_table :articles
   end
end

Controller: app/controllers/articles_controller.rb (NOTICE THE BUILD ON NEW
ACTION...)

class ArticlesController < ApplicationController
   # GET /articles
   # GET /articles.xml
   def index
     @articles = Article.find(:all)

     respond_to do |format|
       format.html # index.html.erb
       format.xml  { render :xml => @articles }
     end
   end

   # GET /articles/1
   # GET /articles/1.xml
   def show
     @article = Article.find(params[:id])

     respond_to do |format|
       format.html # show.html.erb
       format.xml  { render :xml => @article }
     end
   end

   # GET /articles/new
   # GET /articles/new.xml
   def new
     @article = Article.new
     @article.globalize_translations.build

     respond_to do |format|
       format.html # new.html.erb
       format.xml  { render :xml => @article }
     end
   end

   # GET /articles/1/edit
   def edit
     @article = Article.find(params[:id])
   end

   # POST /articles
   # POST /articles.xml
   def create
     @article = Article.new(params[:article])

     respond_to do |format|
       if @article.save
         flash[:notice] = ''Article was successfully created.''
         format.html { redirect_to(@article) }
         format.xml  { render :xml => @article, :status => :created,
:location => @article }
       else
         format.html { render :action => "new" }
         format.xml  { render :xml => @article.errors, :status =>
:unprocessable_entity }
       end
     end
   end

   # PUT /articles/1
   # PUT /articles/1.xml
   def update
     @article = Article.find(params[:id])

     respond_to do |format|
       if @article.update_attributes(params[:article])
         flash[:notice] = ''Article was successfully updated.''
         format.html { redirect_to(@article) }
         format.xml  { head :ok }
       else
         format.html { render :action => "edit" }
         format.xml  { render :xml => @article.errors, :status =>
:unprocessable_entity }
       end
     end
   end

   # DELETE /articles/1
   # DELETE /articles/1.xml
   def destroy
     @article = Article.find(params[:id])
     @article.destroy

     respond_to do |format|
       format.html { redirect_to(articles_url) }
       format.xml  { head :ok }
     end
   end
end

Views: app/views/articles/

index.html.erb

<h1>Listing articles</h1>

<table>
   <tr>
     <td>id</td>
     <td>title</td>
   </tr>

<% for article in @articles %>
   <tr>
     <td><%= article.id %></td>
     <td><%= article.title %></td>
     <td><%= link_to ''Show'', article %></td>
     <td><%= link_to ''Edit'',
edit_article_path(article) %></td>
     <td><%= link_to ''Destroy'', article, :confirm

   </tr>
<% end %>
</table>

<br />

<%= link_to ''New article'', new_article_path %>

edit.html.erb

<h1>Editing article</h1>

<% form_for(@article, :html => {:multipart => true}) do |f| %>
   <%= render :partial => "form", :locals => {:f => f}
%>
   <p>
     <%= f.submit "Update" %>
   </p>
<% end %>

<%= link_to ''Show'', @article %> |
<%= link_to ''Back'', articles_path %>

new.html.erb

<h1>New article</h1>

<% form_for(@article, :html => {:multipart => true}) do |f| %>
   <%= render :partial => "form", :locals => {:f => f}
%>

   <p>
     <%= f.submit "Create" %>
   </p>
<% end %>

<%= link_to ''Back'', articles_path %>

_form.html.erb

   <% f.fields_for :globalize_translations do |trans| %>
     <p>Locale: <%= trans.text_field :locale %></p>
     <p>Title: <%= trans.text_field :title %></p>
     <p>Text: <%= trans.text_area :text %></p>
     <br/>
   <% end %>

show.html.erb

<p><%= @article.title %></p>
<p><%= @article.text %></p>
<%= link_to ''Edit'', edit_article_path(@article) %> |
<%= link_to ''Back'', articles_path %>

Routing map: config/routes.rb

map.resources :articles

rake db:migrate
script/server

Then try to insert a new article using: http://localhost:3000/articles/new
Locale: en
Title: Test title
Text: Test text

When try to create the record nothing happens, but if I create the record in
console:

Article.create(:title => "Test title", :text => "Test
text")

the edit and update operations works well...

I don''t understand why I can''t create new records with nested
attributes using the view...

Re: Problems using Globalize 2 crud with rails 2.3 nested attributes

Hi,

have you solved this now? Your idea of using the globalize
translations as a nested attribute
seems interesting. I was just wondering why you don''t just let
globalize handle the globalization
stuff transparently in the background. You can then simply create
events for different locales
by switching to the locale you want before creating the event. I do it
that way, storing the locale
as a hidden field in the form.

Best Regards,
Nico

Re: Problems using Globalize 2 crud with rails 2.3 nested attributes

The association name changed from :globalize_translations to 
:translations. Maybe is this is your problem?
