Plugins - Custom Resource Name
Add to favoritesThe Custom Resource Name Plugin lets you add aliases for your routes. This is very useful if you are developing a software to a country that does not speak English and wants all URLs in the native language.
To use it is simpler yet. Open the file routes.rb of your project and include the following lines BEFORE the routes that should be translated:
# translate resources
map.aliases :resources, :posts => ‘artigos‘, :comments => ‘comentarios‘
# translate actions
map.aliases :actions, :new => ‘novo‘, :edit => ‘editar‘, :logout => ‘sair‘
# translate namespaces
map.aliases :namespaces, :admin => ‘administrativo‘
If you have any english route that should stay untouched, put it before the aliases definition.
