How I install multiple django apps on one host by re-using a recipe

recipie_default.rb

node.django_apps.each do |key,value|
    django_app = value
    djangoapp_build_repo django_app.branch do
      action :add
      settings django_app.settings
      repo django_app.repo
      app_name django_app.app_name
      env_root django_app.env_root
      app_user django_app.app_user
      not_if { File.directory?  "#{django_app.env_root}/#{django_app.app_name}-env" }                                                                                                                             
    end 
end.

roles.rb

default_attributes( "django_apps" => {"myapp" =>  {"site_domain" => "example.com",
                   "env_root" => "/var/www",
                   "app_name" =>"bloggyblogger",
                   "repo" => "alexlovelltroy/bloggyblogger",
                   "settings" => "bloggyblogger/__init__.py",
                   "app_user" => "ubuntu",                                                                                                                                                                        
                   "branch" => "master"
                    }})
