Can't change locale in the URL? about routing-filter

[zackxu1]

After reading the source-code, I see what this gem is doing:

The Locale filter extracts segments matching /:locale from the beginning of
the recognized path and exposes the page parameter as params[:locale]. When a
path is generated the filter adds the segments to the path accordingly if
the page parameter is passed to the url helper.

incoming url: /de/products
filtered url: /products
params: params[:locale] = 'de'

You can install the filter like this:

in config/routes.rb

Rails.application.routes.draw do
filter :locale
end

To make your named_route helpers or url_for add the locale segments you
can use:

products_path(:locale => 'de')
url_for(:products, :locale => 'de'))

I added the needed logic to application_controller.rb so it's all working.

As a suggestion, maybe you want to add the above to the gem documentation so it's more clear what this gem is doing for persisting locale.
Thanks, this is a great gem!
