Problems using Globalize 2 crud with rails 2.3 nested attributes


#1

Hi to all !

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

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

Listing articles

<% for article in @articles %>

<% end %>
id title
<%= article.id %> <%= article.title %> <%= link_to 'Show', article %> <%= link_to 'Edit', edit_article_path(article) %> <%= link_to 'Destroy', article, :confirm => 'Are you sure?', :method => :delete %>

<%= link_to ‘New article’, new_article_path %>

edit.html.erb

Editing article

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

<%= f.submit "Update" %>

<% end %>

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

new.html.erb

New article

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

<%= f.submit "Create" %>

<% end %>

<%= link_to ‘Back’, articles_path %>

_form.html.erb

<% f.fields_for :globalize_translations do |trans| %>

Locale: <%= trans.text_field :locale %>


Title: <%= trans.text_field :title %>


Text: <%= trans.text_area :text %>




<% end %>

show.html.erb

<%= @article.title %>

<%= @article.text %>

<%= 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…

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

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