Rails - Dec 2005 - Multi language pages (access @session from a model)

Hi,

I''m creating a simple Ruby on Rails based CMS. It will support multiple
languages. Therefore I''ve a table ''pages'' and a table
''page_translations''. The table ''page''
contains a title and body in the
default language, the table ''page_translations'' contain a
title and body
for an other language.

Now I would like to have an easy way to retrieve the title and body of a 
page given the current language (stored in the session). I would like to 
put this logic in a model (the Page model, or maybe a new model like 
''TranslatedPage''). This way I don''t have to put ugly
code in my
controllers and views everytime to fetch the page for the current 
language.

However, it seems I can''t access @session from the model. Does anybody 
have a good  idea on how to implement this?

Thanks in advance!

Greetings,
- Matthias

Try dropping the @ -- use session instead of @session. Any good?

Yours,

My 0.02$: I think you should normalize your tables, and have

DEFAULT_LANG= ''en''

page_translations
  id
  lang         CHAR(2) DEFAULT en
  mycontent    TEXT

then in your controller you simply do

MyController.show
  @my_model = MyModel.find(12, :include => :page_translations,
                      :conditions => [''lang = ?'',
session[:lang]])
end

Why is this ugly ?
