Polymorphic models

[mongkok]

is possible to create an admin class with translation fields in parent django-polymorphic model?

This is an old issue but for anyone coming across this as I did, it's undocumented but it's doable.

My environment:

• Django 3.2
• django-polymorphic 3.0.0
• django-modeltranslation 0.17.3

models.py

class MyModel(PolymorphicModel):
    title = models.CharField(verbose_name=_("Title"), max_length=200)

class ChildModel(MyModel):
    link = models.URLField(_("link"), blank=True)

translation.py

class MyModelTranslationOptions(TranslationOptions):
    fields = ("title",)


class ChildModelTranslationOptions(TranslationOptions):
    """
    Leave it blank to translate the title (inherited from MyModel)
    or use `fields = ("link",)` if you want to translate the link too
    """
    pass

translator.register(MyModel, MyModelTranslationOptions)
translator.register(ChildModel, ChildModelTranslationOptions)

admin.py

@admin.register(ChildModel)
class ChildModelAdmin(TabbedDjangoJqueryTranslationAdmin, PolymorphicChildModelAdmin):
    list_display = ["__str__", "link"]

@admin.register(MyModel)
class MyModelAdmin(TabbedDjangoJqueryTranslationAdmin, PolymorphicParentModelAdmin):
    list_display = ["__str__"]
    base_model = MyModel
    child_models = (ChildModel,)
    list_filter = (PolymorphicChildModelFilter,)

Hope it helps
