# Adding translated fields to an existing model

Create a proxy class:

    from django.contrib.sites.models import Site
    from parler.models import TranslatableModel, TranslatedFields

    class TranslatableSite(TranslatableModel, Site):
        class Meta:
            proxy = True

        translations = TranslatedFields()

And update the admin:

    from django.contrib.sites.admin import SiteAdmin
    from django.contrib.sites.models import Site
    from parler.admin import TranslatableAdmin, TranslatableStackedInline

    class NewSiteAdmin(TranslatableAdmin, SiteAdmin):
        pass

    admin.site.unregister(Site)
    admin.site.register(TranslatableSite, NewSiteAdmin)

## Overwriting existing untranslated fields

Note that it is not possible to add translations in the proxy class with the same name as fields in the parent model. This will not show up as an error yet, but it will fail when the objects are fetched from the database. Instead, opt for reading Making existing fields translatable.
