Internationalize NestaCMS

Internationalising Nestacms

See the following website to get an easy version of app.rb I needed a simple website that I could internationalise to support english, bahasa and tetum. I had some experience with rails but have been very happy using Nesta for simple sites. So I plugged away at getting this to work and eventually I only had to update the app.rb file to enable this.

gem

The updates to Nesta are getting the iI8N gem installed. The locale files are installed in config/locales (like rails but clearly you can change this below) Gemfile add: gem 'i18n' In app.rb add require 'i18n' require 'i18n/backend/fallbacks' configure do I18n::Backend::Simple.send(:include, I18n::Backend::Fallbacks) I18n.load_path=Dir[File.join(settings.root, 'config/locales', '*.yml')] I18n.backend.load_translations I18n.locale = 'en' end

Headers

Making sure that the page headers are translated before they are shown on the site (Nesta grabs the first h1 value on each page to set the headers on the website) I added the last two lines to the default Page.heading code. This evaluates the h1 command and currently ONLY WORKS for haml. (eg %h1 next line = = I18n.translate('index.heading') ) class Page def heading regex = case @format when :mdown /^#\s(.?)(\s#+|$)/ when :haml /^\s%h1\s+(.)/ when :textile /^\sh1.\s+(.*)/ end markup =~ regex val=Regexp.last_match(1) or raise HeadingNotSet val=eval(val[1..val.size]) if val[0]=='=' val end end

Language route

enabling a route to allow the language to be changed. This is obvious and stores the language in the session.
post '/lang/:id' do lang=params[:id] if ['en','tet','ba'].include?(lang) I18n.locale = lang session[:language]=lang end redirect to('/') end

Sessions

enabling sessions (app.rb) enable :sessions. And update the before do code so that the language is set automatically. I also had toe set the session secret to get this to work. set :session_secret, "somesecret" enable :sessions before do if request.path_info =~ Regexp.new('./$') redirect to(request.path_info.sub(Regexp.new('/$'), '')) end I18n.locale = session[:language] if session[:language]!=nil end

Entire File:

Putting it all together looks like: nesta

This was reasonably simple to do. Please check the following site for full details tl lotto. I have attached the update app.rb file below for full details. The key items were adding i8N o gemfile, using sessions and creating a post route for the language. I also had to update the Page class so that any translations would be added to the menus.

module Nesta
class App
not_found do
cache haml("404".to_sym)
end
enable :sessions
set
before do
if request.path_info =~ Regexp.new('./$')
redirect to(request.path_info.sub(Regexp.new('/$'), ''))
end
I18n.locale = session[:language] if session[:language]!=nil
end
configure do
I18n::Backend::Simple.send(:include, I18n::Backend::Fallbacks)
I18n.load_path=Dir[File.join(settings.root, 'config/locales', '*.yml')]
I18n.backend.load_translations
I18n.locale = 'en'
end
post '/lang/:id' do
lang=params[:id]
I18n.locale =lang if ['en','tet','ba'].include?(lang)
session[:language]=lang if ['en','tet','ba'].include?(lang)
redirect to('/')
end
end
class Page
def heading
regex = case @format
when :mdown
s*(.*?)(\s*#+|$)/
when :haml
s*%h1\s+(.*)/
when :textile
s*h1\.\s+(.*)/
end
markup =~ regex
val=Regexp.last_match(1) or raise HeadingNotSet
val=eval(val[1..val.size]) if val[0]=='='
val
end
end
end
