How to: Integrate with custom admins

All you have to do is to extend the custom admin you want to make translatable with the TranslatableAdminMixin functionalities.

Take django-nested-inline library for example.

To make it translatable you can do:

from django.contrib.contenttypes.admin import GenericStackedInline
from nested_inline.admin import NestedStackedInline, NestedModelAdmin
from translations.admin import TranslatableAdminMixin
from translations.models import Translation


class TranslationInline(NestedStackedInline, GenericStackedInline):
    """This can be used like our own `TranslationInline`."""
    model = Translation
    extra = 1

class TranslatableAdmin(TranslatableAdminMixin, NestedModelAdmin):
    """
    This can be used like django-nested-inlines `NestedModelAdmin` but
    it's translatable.
    """

    def get_inline_instances(self, request, obj=None):
        """Override this method in the custom admin."""
        inlines = list(
            super(TranslatableAdmin, self).get_inline_instances(
                request,
                obj
            )
        )
        # use `TranslatableAdminMixin.prepare_translation_inlines`
        self.prepare_translation_inlines(inlines, TranslationInline)
        return inlines

class TranslatableInline(TranslatableAdminMixin, NestedStackedInline):
    """
    This can be used like django-nested-inlines `NestedStackedInline` but
    it's translatable.
    """

    def get_inline_instances(self, request, obj=None):
        """Override this method in the custom admin."""
        inlines = list(
            super(TranslatableInline, self).get_inline_instances(
                request,
                obj
            )
        )
        # use `TranslatableAdminMixin.prepare_translation_inlines`
        self.prepare_translation_inlines(inlines, TranslationInline)
        return inlines
